Are All Disasters a Conspiracy? (Russian Floods)

Earlier this month a flood in the Black Sea region of Krymsk struck in the middle of the night killing close to 200 people. Nearly a foot of rain fell in the mountains and a 20 foot tall wall of water rose in the cities in 15 minutes. Yesterday, Krymsk’s mayor, its district leader and the local emergency services chief were taken into custody for failing to warn the victims. I include background on the issue and some discussion at the end.

A Russian Federation government report on reliefweb.int gives extensive facts and figures of the disaster and response (e.g. “Emergency psychological aid has been provided in… 11,351 cases”) but vivid narratives can be found in the New York Times:

“Lyudmila Dmitriyevna, 64, said she awoke early Saturday to the sound of voices, stepping onto her third-floor balcony and peering into the gloom.

“It was as if I were looking at a stream of clay,” she said. “It was so loud, there were people screaming in the water, and metal barrels, and animals. It boiled and boiled, it covered the streets and the yards, it was all you could see.”

Like many residents interviewed, she said she suspected that the raging flow was a result of an official decision to release some water from a swollen reservoir in the hills above the city — a theory rebutted by scientists from Russia’s environmental monitoring service, who said Friday’s rains swelled nearby rivers with the equivalent of six months’ average precipitation.

But those explanations, like the overtures of officials, have done little to win back Ms. Dmitriyevna’s trust. “Putin came, Tkachev came, the mayor came,” she said. “They deny everything. They are protecting their own interests. Why would they protect ordinary people?”

Her husband then took her by the hand and pulled her away from a reporter, saying that if she gave her full name, “they’ll take you out and shoot you.”

The Times also reported:

Survivors erupted in angry shouts when they learned, during a conversation with Gov. Aleksandr Tkachev, that officials received warning of the danger three hours before the wave hit, but had made no attempt to evacuate sleeping residents.

At the time, Mr. Tkachev — an ally of President Vladimir V. Putin — responded sarcastically to the notion that officials should have taken any action, addressing the hecklers as “my dears.”

“What, are you saying we should have gone to everyone?” he said as he struggled to be heard over the angry responses, according to video of the meeting. “That’s impossible. First of all, with what resources? Secondly, what would you have done — just stood up and left your houses?”

The frustration of the residents comes through in quotes from The Guardian:

"No one told us anything," said one woman standing at the city administration building, who asked not to be named. "Our officials say the dam had nothing to do with it, but everyone here knows otherwise."

A spokesman for the prosecutor general's investigative committee said the reservoir was not involved in the intense flooding. Local prosecutors earlier admitted the gates had been opened, but it was too early to say if that caused the flooding. Nearby towns were untouched….

Many if the dead were elderly. Loskutova described how she saved her 76-year-old mother: "I was screaming, 'Mama mama!' The water came in so fast and hard, we could barely break through the windows. I prayed and screamed for her not to let go."

The two women climbed on top of furniture where they stood until the water almost reached the ceiling, then finally they climbed through broken windows and on to the roof, she said.

"Then I sat with her, wet and naked, for 12 hours on the roof." No emergencies officials came, Loskutova said, and eventually her son arrived with a boat and ferried them to a hospital. "Are we not people?" she asked.

“When the whole life just floats away”

The International Herald Tribune has a good analysis of conspiracies around the idea that the reservoir purposefully released water to flood the town. Here is the text of a social media post fueling one of these theories

“Everyone is keeping quiet about this now, but last night my father was working and he says that they called an emergency meeting in the middle of the night to decide whether to open the floodgates of the Neberdzhaevskoye Reservoir,” Andropova wrote. “And what do you think? Of course they decided to open the floodgates! They sacrificed Krymsk and still didn’t manage to prevent the flooding of Novorossiysk. Good job. But at least they should have warned people the water was coming! Why didn’t they send the police ahead with warnings? Why didn’t they turn on the sirens so people would wake up? Now the stores are closed, we have no electricity or food. Krymsk is surrounded by troops, though there is no longer a Krymsk to speak of — just ruins. Many old people died. My friend’s parents have disappeared: they weren’t home when the rescue crews came, but they haven’t been found in the morgue either.”

Russian media has been contending that the reservoir couldn’t have caused the flood:

The dam of this reservoir is… located on the opposite side of Krymsk. Moreover, the emergency discharge of the reservoir is of a glory-hole spillway design which excludes the discharge of any considerable quantity of water.

The local authorities have reported that there was a discharge of water from the reservoirs, but whether they could have contributed to the flood in any considerable manner is a question that remains to be answered. However, the likelihood these reservoirs were in fact sources for the hundreds of thousands of tons of water that flooded Krymsk remains highly questionable on purely technical grounds.

The basin, located deep in the mountains, may have secured the town from total immersion, it appears. Waters levels in the reservoir jumped from 3 million to 8 million cubic meters overnight, so the storage worked as a “safety bag” for the city, securing it from an even worse flood, the Neberdzhaevsky press service says.

Moreover, “Krymsk was flooded much earlier than the reservoir started draining excessive water,” the press service told RIA Novosti. On Sunday the Investigative Committee confirmed that it does not consider a water discharge from the Neberdzhaevsky reservoir as the primary cause of the deluge…Local authorities insist that the true reason for the flood was the record level of precipitation in the region.

Anger was originally directed at the national government but Russian state media has deflected that back to the regional level:

The regional emergency services reported that local authorities had received weather warnings two days before the disaster. They also say the Emergencies Ministry sent out weather warnings by text message through mobile operators.

Pravda goes so far to say that provocateurs are deliberately spreading false information to undermine support for Putin:

Any cataclysm causes a great deal of rumors and the most controversial speculation. For example, victims of the earthquake in Armenia in 1988 sincerely believed that right before the shocks a silver plane appeared in the sky and something was dropped from it. This is a simple property of the human psyche - to try to explain blind violence of nature by human actions and find the cause that triggered the cataclysm. You cannot flog the ocean for drowning the ship.

The events in and around Krymsk go far beyond the standard reactions of shocked people to a disaster…Today, despite all rebuttals, despite the fact that an independent group from Krymsk has circled Neverdjayevskaya dam reservoir on an airplane, the attempts to fully refute the belief of the people that a wave was directed at them intentionally, have failed. People started talking about other reservoirs in the region from which the water could go to town. They began to look for other causes of flooding, understanding that the "Novorossiysk" theory had failed. Other theories included "drained water from the site of Grushevka Rosneft", "tried to save Putin's dacha in Praskoveevka," etc.

…On July 9 unidentified vehicles in the streets were announcing to the local residents that the second wave of floods was coming. Allegedly, the dam at the reservoir Neverdjayevskaya broke down and another multi-meter wave of water was approaching the city.

These "warnings" have generated a serious panic in the city, people rushed to the roofs of the houses, traffic jams emerged on the exits from Krymsk. Local authorities tried to calm the citizens down for hours, let the police cars on the streets urging people not to give in to provocations, explained that there was no second wave and the reservoir was fine.

Provocateurs were not found. In a dilapidated, panic-ridden city, the search and identification of criminals has become a real problem. However, the mere appearance of such "warning vehicles" is remarkable. It means only one thing - there is an organized group of provocateurs in Krymsk seeking to undermine the situation, politicize the disaster, and direct anger and frustration of people in the direction advantageous for the manipulators.

The Moscow Times puts a finer point on it (my emphasis added):

This is a well-known psychological phenomenon and very bad news for the authorities. It is common for victims of natural disasters to believe that they were victims of an evil plot of some sort. The famine of 1317 was blamed on Jews, and the black plague epidemic of 1347 was blamed on Jews and witches, who were subsequently burned at the stake.

This is bad news for the authorities because the people of Krymsk do not blame their troubles on Jews, witches, U.S. State Department, foreign agents or anti-government protesters. These once-steadfast supporters of Putin place the blame squarely on the Russian government.

The Christian Science Monitor also calls this a “familiar pattern”:

"There is a by now familiar pattern that repeats itself every time there's an accident," says Nikolai Petrov, an expert with the Carnegie Center in Moscow. "People blame officials, often with good reason, for failing to protect them. Central authorities look for someone on the local level to attach the fault to, and local officials squirm and lie to evade responsibility."

Is it true that victims of natural disasters often believe they were victims of an evil plot? The theme of “Flooded residents direct anger at reservoir operators” was one that I heard commonly this year, such as during the Queensland Floods and in the Manila Typhoons. I heard stories in the Philippines of citizens believing a dam was flooding their city, an idea easily refuted by looking on a map and noticing that the dam was over in the next valley and had no control over the local rivers.

Compare this headline “In terrorist attack, Putin destroyed whole town in Caucasus to save his Black Sea palace” with this story from Bangkok a few months agoThe king refused his palace to be protected from the flood, arguing that the water would just go around it, and it wouldn’t do any good to anybody else. No wonder they like the king here. But there is resentment in the outer provinces of Bangkok, about the suspicion that their neighbourhoods were sacrificed in order to save central Bangkok.” (read more about politics and floods in the US, Bangkok and Jakarta).

The IHT article touches on the central problem with muddling natural and man-made disasters:

“We shouldn’t be making up crimes where there were none,” Shultz added. “Especially since there are plenty of specific and true reasons to be mad at the regime.”

To a Russian, both versions of events are believable — except that a story imputing malice to the authorities is probably more plausible than a sudden natural disaster. We Russians no longer believe anyone who addresses us in the public sphere: the president, the television, the newspapers, the police or bloggers we don’t know personally.

Thus in addition to the tragedy of the people who died in Krymsk, there’s the tragedy of having no hope of ever knowing what really happened to them.

UPDATE: A new theory emerges…Is this also a part of the “familiar pattern”, that a scientist armed with data (measured from outer space, no less) would waltz into a messy and contentious politicized issue? From the financial times

Lev Denisov, head of the Laboratory of Remote Sensing at the Institute of Geography of the Russian Academy of Sciences, has another theory which many experts say offers a more probable explanation. The flood’s force, he said, was caused by water being channelled through small openings in a raised highway south of the city.

Using photographs taken from the International Space Station, his team pieced together the path of the flood waters, which he said built up behind a 7m-high road embankment south of the town, as well as a raised railway, by late evening on July 6. The waters were held back by logjams of debris which temporarily clogged eight narrow bridge openings.

“When the pressure became too high, the debris clogs burst, unleashing this wall of water,” Mr Denisov told the FT.

He pointed out that the height of the wall of flood water was roughly similar to the height of the highway embankment – 7m – and dismissed the theory that the floods were caused intentionally….

Suren Gazaryan, an ecologist based in southern Russia who was one of the early champions of the artificial cause theory, announced last week on his blog that he had changed his mind. “I came to the conclusion that discharge of water from the Neberdzhaisk reservoir could not be a major cause of the flood, although residents [of Krymsk] adhere to this version,” he said. He said on twitter on Saturday that the highway construction was “an obvious reason” for the floods.

Largest Area Natural Disaster in US History

The UK daily mail has this headline America burning: Drought devastating 26 states is the largest natural disaster area in U.S. history. Here is a picture of the weekly monitor of drought status across the US. In the history of the drought monitor product, this is the first time such a large area has been covered in drought.

drmon

Here’s my chart of how the area in drought has changed over time:

DroughtMonitorAreaSmall

They say that drought is a creeping disaster. This was two years in the making, but has rapidly accelerated in just the past few weeks.

Today the USDA formally declares over 1,000 counties in 26 states as agricultural disaster areas. The map of those areas is here:

Which US Cities Have The Best Weather?

Climatologist Jan Null created a “Camelot Index” to measure which cities have the ideal weather. From his page

“In this 1960's musical King Arthur professes that Camelot has a perfect climate all the year; and by royal decree at that! But actually an "ideal" climate is extremely subjective, with one person's idea of perfection being met with disdain by others. Some individuals may want warm beach weather all year round, while four distinct seasons are most desirable for others. What follows is just one person's (the author's) idea that an ideal climate is sunny and relatively mild with few extremes in temperature, humidity or precipitation.”

Here’s the map of the index, with higher numbers meaning better weather:

 camelot_climate

Here’s the top 10 best weather cities in the US

1 San Diego CA
2 San Francisco CA
3 Los Angeles CA
4 Sacramento CA
5 Eureka CA
6 Las Vegas NV
7 Fresno CA
8 Redding CA
9 Galveston TX
10 Key West FL

Not that surprising that California holds 7 of the top 8 spots.

And here’s the bottom 10 worst cities

Colorado fires hit home, literally

Three days ago, my wife’s parents’ home in Colorado Springs was consumed by the Waldo Canyon fire. The news came as a brief note:

“The alarm company just called and the whole house exploded. All of the window alarms went off.”

Within a day, an image was emailed showing the property as a smudge of white ash. 

Pic of Subdivision

The house was in the upper left of the yellow box

Later it appeared in the middle of a channel 9 video:

ColoSpringsPhoto

Other video from channel 9 shows homes turning into fireballs at night against the dark silhouette of the mountain:

ColoSpringsPhotoNight

The reporter describes: “This is really very close to that worst case scenario that so many people in Colorado Springs talked years and years about. This is why people were so adamant talking about mitigation efforts… and that when you have to evacuate, you may have to do it quickly. And that happened for tens of thousands of people today.”

A fleeing resident describes leaving irreplaceables behind

My heart was pounding as I made one last sweep through our little house in Raven Hills. I wondered if my family would ever celebrate another birthday here. I paused at the window where we saw so much wildlife in the woods outside. Where we always put up our Christmas tree.

In the garage, I stopped at the wall where we traced our kids’ profile, measuring their heights to document their growth over the years. I took one last picture of the shark mural in my youngest son’s bedroom, grabbed my oldest boy’s high school letterman’s jacket, took a photo of my daughter at Disney World and began our escape.

He then witnessed hell in the rearview mirror:

Intersections were blocked by panicked drivers trying to escape. Sirens wailed all around. I felt trapped in a horror movie… I had to go west, toward the flames, to escape. But that route was blocked as well.

Finally, I went into four-wheel-drive, hopped a curb, blasted down a hill, across a soccer field and over a trail to reach Rockrimmon Boulevard where six lanes of traffic were headed east on both sides of the median.

And there I sat in traffic. It’s a memory I’ll never forget. I teared up as I scanned the surrounding cars. Everywhere were children, scared and crying, their parents looking deathly afraid and, in my rearview mirror, a view of the gates of hell.

A friend on facebook shared this photo of the fires above Boulder

That kind of disaster never seems to happen to someone you know, until it does.

“It was like a scene from Armageddon” Cork, Ireland Floods

Yesterday 50 mm of rain fell in about 3 hours near Cork, Ireland.

The #corkfloods twitter feed is a good source for the latest information and the Irish Examiner has several stories of the resulting floods, such as this one with the headline “Everything is just destroyed again — for the fourth time”.

Cian Coleman had to help emergency services take his pregnant girlfriend Michelle McCarthy to safety: "I went downstairs and the dog was swimming around the kitchen. It was coming in through the door and I was trying to push the door in. Michelle has only two weeks to go, they took her out in a boat, which was floating in water above the front wall outside."

As [someone whose house had been destroyed] started to wade back through the drive to her front door, her daughter Fiona returned from a check on their neighbours.

"Look what someone’s after giving me," handing her mother a pink-covered photo album that was found in a nearby green area. It had clearly been among the items from their front room carried out the door in the early hours.

"They just came up and asked did I know who it might belong to. I opened it up and there was a picture of myself," said Fiona, laughing at the coincidence and irony of an otherwise disastrous morning.”

The Irish Examiner also has this eye witness account:

“The first inkling I had that something was wrong was sometime before 5am when I heard a car go through the estate — Meadowbrook in Glanmire — with the driver beeping and roaring out the window.

I was all set to give out to him until I looked out the window and saw what looked like a river running through the estate.

I rushed downstairs and tried to stop it coming through the door but at that stage, it was too late. It was a strong torrent of water and there was nothing I could do to stop it.

The power of it had to be seen to be believed. It flowed straight into the estate. It was covering the floor of our cars at that stage.

We all managed to get out, we got our dog Sophie out, and we were lucky enough to save our cars. Then all we could do was lock the door of the house and leave…

It was as high as five or six feet in some parts of the estate. The fire brigade rescued those who couldn’t get out of their homes, and helped others move upstairs.

By the time I got back to my house, it had been ruined. All the floors had come up, the furniture was destroyed, but we were no different to anybody else. Luckily, no one was injured or killed.

I managed to wade to other parts of the estate where the water was even higher. I knew there was an elderly man living nearby who slept on the ground floor of his house, so myself and two firemen managed to wake him up and move him upstairs in his house.

It was like a scene from Armageddon. The fire brigade had brought a RIB [Rigid Inflatable Boat] and punts to rescue people, water was nearly covering the cars. It was something else…

One woman on the estate had her goldfish bowl washed away but the goldfish were found swimming around the garden and rescued by hand, which was pretty amazing.

Ironically, I got a text message telling me of a flood warning in Bandon. I was standing up to my waist in water when I got the message, thinking ‘What about bloody Glanmire’s warning?’

It felt a little bit like the blitz in England during the war. Everyone pulled together. The community centre was offering teas and coffees to people and Liam Griffin from SuperValu sent across a load of grub.

It was a hairy few hours. It will take weeks to clean up. Looking around, what was a sea of water just a few hours ago is now a sea of mud.”

More animals in the streets/The cone of uncertainty

Following on the recent post about a seal running around in Duluth, a twitterer tweeted this photo of an alligator using a crosswalk recently during Tropical Storm Debby in Florida.

Croc2

Like that other post, there are lots of photos of submerged cars in Florida:

  Croc

Perhaps the most interesting to me though was to see the hurricane path forecasts of Debby. Here’s South Florida Water Management District’s plot of the computer model guidance from 3 days ago (22 of June 2012):

storm_96

Each line is the possible track of the eye of the hurricane, as predicted by 15 different forecasting models run by various agencies. Things seem sure for the first 2 days that the storm will head north, but then after that it was anyone’s guess if it would head west to Texas, north or east across Florida.

Here’s the actual path (in purple) with another way of displaying the most recent forecasts (i.e. as a cone of uncertainty, than a spaghetti of possible scenarios).

track

And then here’s the equivalent spaghetti plot for the most recent model runs:

storm_04

Notice a tighter clustering of the model runs now, they all head off in the same general path. The important thing to take away from this is that sometimes weather models give confident results with high certainty, but in some situations the results can be all over the map (literally). In theory, sometimes the cone of uncertainty should be narrow, sometimes fat.

Do notice, however that the legend for the graph labels the orange cone “historical std dev [standard deviation]”, a measure of the typical error versus leadtime for all the historical predictions, averaged over a number of years. The width of this cone then, in practice, doesn’t change, even if the forecasters know that a particular situation is more uncertain than another. That said, requiring the forecaster to predict both the center of the cone and its width every time is an extra operational workload, and it’s something that takes extra training to do accurately.

Flood causes seals in the streets of Duluth

Photos are coming from Northeast Minnesota, US, showing record or near record flooding. One of those includes a seal waddling down Grand Avenue:

20120620_duluth_seal_53

The original caption reads “This seal is one of two that escaped from the Lake Superior Zoo in Duluth during last night's floods. Zoo officials say the seals were returned safely.”

Strangely enough, this is the second story I’ve read today about exotic animals run amok during a flood. Earlier today I discovered the story behind a photo of a lion holed up in a church during a Texas flood a few years ago. That article includes a quote from a local “When you think you've seen everything, you find something else”.

NPR’s audio story from Duluth describes how aging water pipes have cracked, burst, then sucked down gravel to form sinkholes that have swallowed cars, like so:

20120620_duluth3_53

Some of the pipes and a manhole cover are visible in the above picture. Original caption: A car fell into a huge sinkhole in Duluth, Minn. on Wednesday, June 20, 2012. Duluth Mayor Don Ness said he would declare a state of emergency after the deluge of up to 9 inches of rain that he said caused extensive damage to the port city of about 86,000. Ness said the order would start the process to obtain federal aid. Gov. Mark Dayton said he would travel to Duluth on Thursday to discuss how the state can help.

Hydrologic Oddities: Turf blisters

There is a recent video from Portland, Oregon showing someone jumping up and down on a patch of grass like a trampoline:

 

CBS News says that a reader explains:

Depending on where exactly this is, often times, landscapers will lay down plastic sheet on bad soil then plant sod on good soil laid on the plastic. If this is the case, a water line may have broke and now you have water under the plastic liner, hence the bubble. If it's not liquid, natural gas could also be a cause. The safe bet is though, there is a plastic liner under the sod and whatever is under the liner has caused the bubble.

There's an animated gif of someone walking on a turf blister:


20eb78ef9a38d49b89381ad30f474f52173323df

Easily, the most impressive example comes from Greywolf Golf Course where this 18" high blister formed because of a pipe that broke under “creeping bentgrass on our fairway that has two much thatch.”

 GrWolfGC

 

Greywolf also has this video of the blister popping:

 

But for a further introduction, here's an enthusiastic place to start with videos of bubbles under grass:

 

 

This dog didn’t quite know what to make of the bubble:

Because of the combination of artificial grass and underground pipes, these things seem to happen at golfcourses, such as this video:

Here some golfers laid down on the blister like a waterbed:

 

At around 0:16, a golfer lanced one of the boils with a club:


After popping this blister, water gushed out:

Hug a climate scientist day

June 10th is hug a climate scientist day. According to “Crikey”,

Did you know that our own decent hardworking Aussie Climate Scientists regularly receive death threats and are sent pictures of dead animals? It is true…. This situation got so bad at he Australian National University, they had to move their climate scientists to a secret location… We need to let our climate scientists know that we love them and appreciate their hard and very important work.” 

 

HugAClimateScientist

Find a climate scientist, give them a hug and let them know it’s going to be alright.

After that, maybe you want to post a photo on the “I *heart* climate scientists” facebook page.

Hydrologic oddities: The loss of happiness in France

The happiness is lost in France.

Specifically, “The Happiness River” (Le Bonheur) in southern France flows along the surface for a bit until it reaches limestone rocks. From there, the river disappears underground at a place called “The Loss of Happiness” (La Perte du Bonheur).  

Perte_bonheur

Where The Happiness disappears

Hydrologist Vazken Andréassian (a fellow fan of strange rivers, which he calls “monsters”) indicated to me that there was something uniquely French about a place where happiness is literally driven into the ground.    

Where the river emerges is called Bramabiau, named after the word for ox. From one description (google translated) “During high water, this resurgence with its waterfall is loud, which is amplified by the walls of the canyon, like the cries of an ox”.

wp8ef14f86

Shortly downstream, the river comes back to the surface at “The Abyss of Bramabiau” (l'abîme de Bramabiau).

We can only hope that the French spirit is just as boisterous when the happiness returns.

56 Years of Tornado Tracks

For the storm chasers (and streamchasers) out there- here is IDV's map of tornado tracks across the US using freely available information from data.gov. Each streak connects tornado's touchdown and lift-off location (the actual tornadoes meandered around a bit more than is shown here). The brightness is how violent it was. There is also a high resolution version.

Tornado tracks
The National Weather Service also has plenty more visualizations of this tornado data including maps of the tornadoes that happened in each year. It would be interesting to animate this like has been done with paths of airplane flights.

How much money are US hydrologists earning?

How many hydrologists and meteorologists work for the US federal government? Which agencies do they work for? And how much money do they get? How does this compare to weather forecasters?

The bottom line first

For the busy readers, here’s my overall impression: the typical mid-career NOAA river forecasting hydrologist makes about $100k (US dollars per year, which is about 80k euros). This is a few thousand dollars per year more than meteorologists. Hydrologists that work outdoors earn less than those with desk jobs (e.g. the typical Forest Service hydrologist earns $70k). The positions (i.e. hydrologic technicians) that don’t require a degree, earn about $30k less than otherwise.

salary

I hope those numbers are in metric. (source)

The database

Let’s take a tour of the online database of what nearly everyone in the US government is earning. The database is a good source for statistics so I wrote a little computer program to pull down the numbers and see what was there. That said, it can seem voyeuristic to be able to search for individual employees by name and find out their salaries and bonuses. In three clicks you can find out who the highest paid hydrologist in the government is. In four clicks you can find some of the lowest paid workers (Soil Conservation Technicians in Wyoming, we feel for you!)

Job titles for hydrologists

Here is the government’s job description of a Hydrologist (series GS-1315):

This series includes positions that involve professional work in hydrology, the science concerned with the study of water in the hydrologic cycle. The work includes basic and applied research on water and water resources; the collection, measurement, analysis, and interpretation of  information on water resources; the forecast of water supply and water flows; and the  development of new, improved or more economical methods, techniques, and instruments.

The “Meteorologist” position is similar, except substitute “weather” for “water” in the above paragraph. There is also “Hydrologic Technician”… Technicians are typically the people that install, maintain and repair instruments out in the field, but also spend time in the office reviewing and cleaning up data. Hydrologists typically need to have an advanced degree, whereas technicians do not.

Note that this doesn’t capture all the people that may work on water topics but are not themselves hydrologists, such as computer specialists, economists, natural resource conservationists, or people doing “general physical science”.

Also, while all river forecasters are hydrologists, there are many hydrologists that are not river forecasters. There are hydrologists that are focused on water quality and groundwater and many other sub-fields. This analysis does include river forecasters that work for federally owned hydropower companies (such as Bonneville Power) but not those in the private sector (such as Salt River Project). It also doesn’t include state and local government, only federal. 

It is easy to get distracted by all the other government job titles like “Sewing Machine Operator” or “Nuclear Materials Courier”. I can only imagine what a “Wiper” or an “Oiler” does, or if they get along with each other? How about the “Messengers” (of which there are 10 serving a city of 5,000 people in Arizona)? There are “Barbers”, “Buffers”, “Bakers” and even “Bulk Money Handlers”.

How many hydrologists are there?

For a country of 313 million people, there are 2.6 million federal employees, 177 thousand of which work in natural resources. There are 2,342 hydrologists, 2,789 meteorologists and 1,602 hydrologic technicians. It’s a rare profession indeed- if you introduced yourself to 20 strangers a day in the US, it would take on average over 18 years to meet a government hydrologist. Strangely, the government hires about as many Meteorological Technicians (371) as it does Funeral Directors (345).

What agencies do these people work for?

Far and away, the Geologic Survey (USGS) is the largest federal employer of hydrologists (60%) and hydrologic technicians (78%). This is the agency that maintains the stream gage network in the US and also works on mapping groundwater, among other things. 

Similarly, if you want to be a government meteorologist, the National Oceanic and Atmospheric Administration (NOAA) is where 98% of the jobs in that field are. NOAA contains the National Weather Service. Meteorologists outnumber hydrologists 9 to 1 at NOAA.

Other places where a good number of hydrologists work include the USDA, National Parks Service, Bureau of Land Management, Forest Service, the Bureau of Reclamation and the Environmental Protection Agency.

How much money do they make?

Salary and bonuses of Hydrologists, by government agency, sorted by median income per year in 2011. Redder colors mean relatively more money.

The columns on the left and right give a range of the salaries within the agency. For example, if you look at the first row, 8 in 10 hydrologists at the Environmental Protection Agency make between $69k and $135k per year, with half of the people making more than $113k. For reference, median income of all wage earners in the US in 2010 was about $26k per year (not including bonuses). Bonuses for hydrologists are typically not much, often less than a thousand per year.

In other words, EPA and NOAA hydrologists earn about $30 thousand a year more than those at the Forest Service. Another standout is the Agricultural Research Service (ARS). It only employed 33 hydrologists but many of them were very well compensated. Two of the top three highest paid hydrologists in the country work for the ARS, making more than $170 thousand per year.

Here’s the same table, except for hydro techs (for agencies with substantial numbers of them). All in all, hydrologic technicians make a little more than half what regular hydrologists make. Again, the main difference is that hydrologic technicians typically do not need an advanced degree.

Hydrologists versus Meteorologists

If you remove the top 25% of earners in each category (i.e. you just consider the typical employee and those just starting) meteorologists earn about $5-$10 thousand more per year than hydrologists. This is likely because meteorology is more of a desk job and there are many hydrologists (e.g. at the National Park Service and Forest Service) that spend about half their time outdoors collecting data.

Therefore, it would be more apples-to-apples to compare hydrologists and meteorologists only within NOAA. These hydrologists are likely to be operational forecasters working for the National Weather Service (NWS) River Forecast Centers. Here, the median salary for hydrologists is more than meteorologists ($100k and $97k respectively). The difference gets bigger towards the low end, i.e. 1 in 20 NOAA hydrologists earn less than $69k, whereas 1 in 20 meteorologists make less than $50k). I suspect that there’s a large pool of junior meteorologists within the NWS and some of them branch out into a hydrology specialty. The difference in pay may reflect a difference in seniority and time with the agency.

More resources

The US Geologic Survey employs the most hydrologists of any agency and have a description of what hydrologists do. Elsewhere on the web are also descriptions of salaries of hydrologists (in 2010), advice on how to become a hydrologist. My top pick is stateuniversity.com’s page of hydrology career facts. The salary numbers on those pages may be lower than what I mention because they may only include entry-level positions?
