More on the India Monsoon flooding/weather.

India Flooding Death Toll Doubles Again in Kerala State; More Than 320 Killed
Quote
More than 320 people have died in the last nine days in floods triggered by intense monsoon rainfall in the southern Indian state of Kerala, the latest tragic flooding event in what has been a devastating season for the country.  Officials told the Associated Press that the floods have left more than 220,000 people homeless over the course of several months. Schools and Cochin International Airport – one of the country's busiest – have been closed because of the disaster.  Many of the victims were killed in mudslides triggered by the heavy rainfall, according to BBC.com.

"We're witnessing something that has never happened before in the history of Kerala," Chief Minister Pinarayi Vijayan told the media. "Almost all dams are now opened. Most of our water treatment plants are submerged, motors are damaged."

Other officials have said this is Kerala's worst flooding since 1924, when more than 11 feet of rain fell during the monsoon and flooded much of the state, India Today reported. India's met department said the state has received nearly 7 feet of rain since June 1, all of which has been attributed to the monsoon season, the report added.


The state is trending some 30 percent above average, and forecasters fear Kerala will approach the 1924 rainfall total before the monsoon season ends in September, India Today also said. With more rain expected, India's met department placed the entire state under a red alert, and state officials held emergency meetings with Prime Minister Narendra Modi late Wednesday night, according to Al Jazeera.

"There are heavy rains every year, but the city has never been flooded so badly," district official Mini Eldho, who left her home in the city of Cochin and fled to a relief camp, told BBC.com.  Since the monsoon season began, more than 1,000 people have died in flooding and mudslides across India.  Kerala state, located in southern India, is home to some 35 million people.

Kerala is a beautiful land. High rates of literacy, fine marijuana, and the local hooch (arack, made from coconut milk) is surprisingly palatable. Matriarchal society, and a communist state government.

The one saving grace here is that the people are natural watermen, the land has many rivers, and children grow up as much in the water as out. Even so the death toll is quite horrific.

To fill in some detail, kerala is a sliver of the south west deccan peninsula facing the arabian sea. There is a ridge five to eight thousand feet parallel to the coast, against which the monsoon hurls itself yearly. Heavy rain is familiar, what set this event apart was the duration.

I forgot to mention, among its many other admirable products, the coffee is to die for.

Just reporting in from visiting family in Saalbach, Austria. After a record hot, dry summer, the promised thunderstorms arrived last night, flooding the valley and destroying stretches of the road; some villages are cut off. Luckily looks like no-one has been injured, at this stage, but numerous hotels must have been inundated along the banks. There are some Youtube videos appearing, like this one:


The damage is largely due to the long hot, dry spell leading to extremely rapid runoff resulting from unusually intense thunderstorms (torrential rain for around 5 hours, lightning everywhere, hail...). Based on how much mud is being carried, there's been a lot of erosion, and probably landslips. More heavy rain is promised for  the next three days, which is going to make rebuilding the road difficult.

"Houston, too close to New Orleans ...."

" ... savoring his $30,000 floodproofing investment ..."

"But if the water that had once sat on the golf course went downstream, where would it end up? "

"He used to work as a seismic engineer in oil and gas ..."

" ... rainfall is up 26 percent over the past 40 years—but runoff is up 204 percent. From 1996 to 2011, impervious surface in Harris County increased by a quarter, and from 1992 to 2010, the area lost almost a third of its wetlands—nearly 16,000 acres."

"Engineers who sign off on developments, assuring the public they will not contribute to flooding, bid for work from developers, who hire engineers who can make things pencil out. "

"the county must find a way to end this cozy relationship between engineers and their dual masters, developers and (according to state licensing) the public."

"Houston’s long-term strategy must simply be to evacuate the 100-year flood plain. It’s the equivalent of demolishing a midsize American city. "

From Weather Underground's Cat 6:
Quote
From the NWS in Houston: "Our local flash flood decision tree is indicating a high risk of flash flooding with maximum rainfall totals by Monday evening between 8-10 inches. What is worrisome is that the TT WRF is showing a boundary and training cells over Galveston/Brazoria and southern Harris counties Monday morning (09-18z). A Flash Flood Watch will be required tonight and Monday for a large part of SE TX."
NOAA's 7-day precipitation projection shows over 7" (18 cm) of rain near Houston.

Millions More Americans Face Flood Risks Than Previously Thought

A New Approach to Calculating the 100-Year Floodplain
Over the past 5 years, researchers across the globe have started to develop a set of these alternative top-down approaches to flood inundation modeling over vast areas, taking advantage of increasingly available large data sets and high-performance computing resources. These methods take available digital elevation models (DEMs), river hydrography, and gauging station data and use them to automatically create flood inundation models of whole regions, countries, or even the world.

Such approaches do not currently outperform local bespoke modeling, but many flood management questions can be answered only by consistent flood maps with the type of complete coverage that these top-down methods produce. For many flood management questions, it may also be acceptable to sacrifice a small amount of local accuracy to achieve a national-scale view.

The consequence of Florence was mainly FLOODS. The article shows how there was building development where one shouldn't including draining wetlands, the response to floods is to build higher & bigger & more levees and dams and drain the swamps, but the real solution is to move to higher ground and restore wetlands, i.e. retreat.

Perhaps one can call it an example of geoengineering syndrome? (see "geoengineering-another rush for money" and "what's new in Antarctica" for larger examples ?)

https://www.washingtonpost.com/national/we-need-help-nc-towns-plead-for-dam-levee-upgrades-after-second-major-flood-in-two-years/2018/09/18/1792b788-bb61-11e8-a8aa-860695e7f3fc_story.html?utm_term=.7143d120dbb4&wpisrc=nl_green&wpmm=1

‘We need help’: N.C. towns plead for dam, levee upgrades after second major flood in two years


Quote
When it inundated North Carolina in 2016, meteorologists called Hurricane Matthew a “500-year rain event,” the kind of downpour that was likely to occur once every half-millennium. But then, just two years later, here came Florence, a “1,000-year event” that hit all the same places in all the same ways, if not harder.......

.....The mayor wants to clear the area’s swamps and canals of fallen trees and debris from Matthew and past hurricanes, which he said would allow storm water to drain out of neighborhoods faster.......

.....Ryan Emanuel, an environmental scientist at North Carolina State University who studies the Lumber River, said that dredging and levee projects are not long-term fixes for the escalating problem. Canals and levees have allowed people to build homes on river margins and in swampy areas over the decades, yet research shows that wetlands can mitigate flooding by temporarily storing water after storms. Emanuel said that moving to higher ground and restoring swamps to their natural state are better ways to alleviate the problem.

I have posted here before on the floods in Kerala. Here is something on the aftermath and the remarkable resilience of women. It is not coincidental that Kerala has a strongly matriarchal society.

Those women's meetings can get quite ... rambunctious. Some of the more obscene jokes I have heard in Malayalam have been at predominantly women's gatherings in Kerala.

Welcome to the new normal:

Title: "Old age, neglect and a changing climate are rendering US dams dangerous"

https://www.dailyclimate.org/us-dams-are-in-disrepair-2609229574.html

Extract: ""If you have more intense storms, more frequent storms then those deficient dams can't handle that. And you're going to see more problems where dams are under stress due to the high waters levels or the overtopping," Ogden said.

There are more than 90,000 dams in the U.S., according to the National Inventory of Dams, which is kept by the Army Corps of Engineers. Approximately 15,500 of them are classified as high hazard, meaning in the case of failure, at least one life could be lost.

According to the Association of Dam Safety Officials, the average age of dams in the U.S. is 56 years old. By 2025, seven out of 10 dams will be 50 or older.

It would take approximately $22 billion to rehabilitate the most critical dams, according to the Association.

While the Army Corps keeps track of the amount of high, significant and low-hazard dams in the country, the individual hazard potential for each dam is not available for the public, Kathryn Van Marter, a spokeswoman with the Federal Emergency Management Agency, told EHN in an email."
“It is not the strongest or the most intelligent who will survive but those who can best manage change.”

Majorca flash flood kills at least six on Spanish island

At least six people have died and nine are feared missing in flash flooding on the Spanish island of Majorca.

A huge wave of muddy water engulfed the town of Sant Llorenç des Cardassar, in the east of the island, after a river burst its banks following heavy rain.
Vehicles were swept away, some with their headlights switched on, as water gushed through narrow streets.

...

The area was hit with more than eight inches of rainfall in just a few hours on Tuesday, according to Spanish meteorological agency Aemet.

A northward buckle of the jet stream in the West has left behind an upper-level low-pressure system over the southwestern U.S.

In absence of a jet stream to kick the low out, it has stalled out over the region, pumping in moisture from Mexico and Central America.

This moisture will continue to wrap over the chillier air that has engulfed Texas, ensuring the rest of the week will be shrouded in clouds and rain.

sorry if i appear as a PIA but generally one should be more specific. there are so many statements and talks about americans, germans, spain as cold as norther europe while that's madrid and a few mountains only etc. etc. the flooding has been on the east coast between valencia and barcelona with a surge inland from the coast, all the large rest of spain was not prone to that flood.

further, floods and rainfalls being heavier in that region is at least a bi-annual event, hence some kind of normal with slight variations on scale and exact region. valencia however is almost always involved, has to do with topography as well as prevailing winds from the warm ocean air rising up the mountain slopes and cooling/discharging in the process.

so please forgive me, it's not personal and not post specific but a general observation that most such generalizations don't really draw an accurate picture of what happened and how people and things are. not even in small switzerland people in bern, zurich, mountainside or romandie are the same and by far not. ;)

Hey Magnamentis .. the detail was welcome .

if those like you with fine computer skills etc had filed the original rather than GW , then he would have not needed to do the obviously thankless task of providing the information that he did.

However bare the bones , they gave an opportunity for us all to inform ourselves further and/or as you did .. bring more to the table !

Hey Magnamentis .. the detail was welcome .

if those like you with fine computer skills etc had filed the original rather than GW , then he would have not needed to do the obviously thankless task of providing the information that he did.

However bare the bones , they gave an opportunity for us all to inform ourselves further and/or as you did .. bring more to the table !
 
It is also interesting that this weather is a late display of the combined energies of the late Hurricanes Leslie and Michael .... b.c.

hey, thanks for the feedback. even though i read every thread out of general interest i never posted in this thread except perhaps in respons. for me floods have happened and will happen most of the time so i have no special interest and to measure the scale is a bit futile without proper longterm stats in locations where there are quite frequent. this is why i did not post myself.

in case i was not clear a gladly say it again, it was an opportunity to point at something general and not specifically on topic and by no means personal. somehow i even felt uncomfy and was afraid it would come across wrong, which is why i relativated it, thought to take the sting out of the post that way.

basically i had the pic ready because i sent it to my friend near valencia to make him aware of his luck and how close it was (he's living at the very southern edge of the area with super heavy rains.

BTW, where i live at the "costa del sol" the color shown was yellow and it was horrible enough.

i had to clean the drainage of the terrace 3 times and listened very carefully at the wall whether the roof is indeed draining, 3 years ago i had 30cm of water on the roof due to blocked drainage and that was freightening considering the weight imposed on the roof above our heads.

again sorry for any inconvenience and hope i was able to still convey the part that i thought is worth to bring it up. ;)

Austin Urged to Boil Water as Texas Flood Shuts Down Treatment Plants – Wettest Autumn on Record in Dallas



Silt and debris from floodwaters have overwhelmed Austin’s ability to produce clean water, prompting an unprecedented citywide alert Monday that urged residents to avoid drinking tap water without boiling it first.

By Monday evening, the situation led to a run on bottled water supplies at grocery stores throughout the region — and appeared to be worsening. City officials warned that water use was outpacing the amount of water being treated, and that residents needed to cut their personal water use by 15 to 20 percent to keep the city from running out of water altogether.

“Austin water treatment plants can currently produce 105 million gallons of water per day. Current customer use is about 120 million gallons per day,” officials said. “Water reservoir levels are reaching minimal levels.”

The current problem is twofold.

The water is so murky and full of silt, measured Tuesday at 250 NTU (normal is about four NTU), that city engineers worry they won’t be able to clean the water to meet federal standards.

Additionally, that dirty water is slowing down the cleaning process, putting the city’s ability to meet customer’s water demand in question. As a result, the city is asking people to continue conserving water.

"We've been providing water for 100 years, this has never happened to us," Meszaros said

Councilmember Troxclair questions why the city didn't see this coming

A flash flood watch remains in effect for Central Texas, including Travis County, through tonight. The area could see an additional 1 to 2 inches of rainfall.

https://www.cnn.com/videos/us/2018/10/23/austin-texas-water-quality-boil-notice-presser-bts-vpx.cnn



A weather pattern stalled over Texas has produced the worst flash flooding since 1935 in Llano County in the central part of the state. The area got as much as 13.24 inches of rain in just the past two days.

The Llano River rose from about 10 feet to nearly 40 feet in less than 24 hours.

Also, Dallas broke the record for the wettest autumn on record -- just halfway into the season. The city has received almost 2 feet of rain so far this fall.

More rain is on the way for Texas on Wednesday and Thursday as flood watches and warnings remain in place for a large part of Texas.

Changes in the occurrence of extreme precipitation events at the Paleocene–Eocene thermal maximum

- Modelling shows a shift in the frequency–intensity relationship of precipitation.
- Incidence of extreme events increases by 70% in some regions.
- Changes in extreme precipitation are often decoupled from mean annual changes.

While the most extreme precipitation rates tend to relate to increases in convective precipitation, in some regions dynamic changes in atmospheric circulation are also of importance.

In New California Disaster Era of ‘Fire-Floods,’ Where Will Deadly Debris Flows Strike Next?
https://www.sacbee.com/news/weather/article219881260.html
https://www.sacbee.com/news/state/california/big-valley/article220570100.html

California is entering what experts call the “fire-flood” era: a formidable one-two punch prompted by warmer temperatures, bigger wildland fires, and more intense winter rain dumps, even in drought years.

Fall fire season sets the table by denuding millions of acres of hillsides and baking the soil surface so that it becomes non-absorbent, or, in scientific terms, hydrophobic. When heavy winter rains hit, the water cannot penetrate the burned soil, and instead rolls downhill in the form of a mud and ash soup, similar to a flash flood, carrying boulders and trees with it.

We know where things are headed,” climate scientist Daniel Swain of UCLA said. “We are just entering this era, and it is only going to get more interesting from here.”

A severe hailstorm hit Rome on Sunday evening, bringing a dramatic end to a long spell of hot weather and covering the streets of the Italian capital in hail and floodwaters.

Drivers found themselves stranded in high waters, while the runoff poured into underground stations. The temperature around the city dropped by 10C during the storm.

An area of low pressure moving south from northern Europe to Italy over the weekend brought disruption to most of the country, with other Italian cities – such as Milan and Palermo – experiencing floods as well.

The region has seen 119 mm (4.7 in) of precipitation in six hours. Countless buildings have been flooded, railway and road communication have been interrupted. Many local residents were left without electricity and gas supplies. More than 350 people were evacuated.

Everyone knows that this will pass and things will return to normal. It happened that way since the beginning of history. Bad times followed by good times. That’s the way it works and everyone knows it.

Except that the climate changed, and the changes are just beginning. I doubt we will have much recovery time from now on. I hope we get a few years to rebuild and regain strength, but I doubt it.

Humanity should be seriously preparing for climate change, but we are not.

Largest Flood Barrier In World Proposed for Texas
https://www.wbtv.com/2018/10/27/largest-flood-barrier-world-proposed-texas/

Quote
GALVESTON, TX – The U.S. Army Corps of Engineers have released their plan to build the largest flood barrier in the world along the Texas coastline.

The Corps of Engineers released their idea for a floodgate system Friday to protect the Galveston region, which could cost as much as $30 billion. (... probably 2-3x that)

The groundbreaking plan includes almost 30 floodgates, which will form a protective barrier to the oil refinery businesses, homes and business owners.

The proposed barrier system would cover 70 miles of coast, starting near High Island, down Bolivar Peninsula, across the entrance to Galveston Bay, and down the Island to San Luis Pass.

Once complete, the main gate across the ship channel would be the largest flood gate in the world at 2,800 feet wide, big enough for two tankers to pass through at once.

The study will be completed by 2021 and submitted to Congress for funding approval.

almost  nauseating to see how those military heads and their fellows from the industry try to find ways to fight the effect by protecting the cause, if it were not sad it were funny.

i'm referring to protecting refineries and allowing two tankers to pass :-(

It would be best if we don't. I hope we have a period of unrelenting damage from weather. One of these category 4 or 5 storms needs to be a direct hit on D.C., flooding and severely damaging our historic monuments and buildings.

Humanity should be seriously preparing for climate change, but we are not.

If we continue to have communities decimated by devastating storms caused by climate change, this will happen sooner.

i've always been of the opinion that things are ultimately self-regulating, only that transitions are painful and destructive for some and that we should be smart enough not to boost but to reduce such effects.

ultimately population of planet earth will be decimated for recovery, the means of decimation there are plenty of them and most probably they will happen in succession. wars famines, floods, earth-quakes and epidemias etc.

Remnants of Hurricane Willa strike the East Coast.

For some, Saturday's flooding almost as bad as Hurricane Sandy

Quote
https://twitter.com/twitter/statuses/1056205668313690113

The coastline of the mid-Atlantic and New England endured the worst of the storm as strong winds led to tree damage in many communities. Wind gusts of up to 67 mph were recorded.

The strong winds blowing the ocean’s water onshore led to moderate to major coastal flooding at high tide from New Jersey to Long Island Sound on Saturday.

In terms of coastal flooding, this storm will rank up there as the one of the worst in recent memory. Tidal gauges at Cape May reached major flood stage. Ocean City, Atlantic City and Barnegat Light were in moderate flood stage.

In my home town, high tides were running ~3.5 ft above normal - significant flooding along the shore (11.1 ft vs 7.8 ft)

The U.S. Army Corps of Engineers is not the military. While they also work for the military (building bases, or support infractructure at war) the main job is large scale civil engineering like building dams and stuff.

If they build a 30+ billion $ thing, it must be worth it in an economic sense. Thus they protect refinieries who are strategically vital for the economy (plus, are a pollution hazard), and not (directly) the house of Joe Sixpack.

Europe will eventually spring to build a sea wall across the Straits of Gibraltar to address flooding of coastal cities across the Mediterranean.

while i generally think that humans should restrain from such things in general, in that case one can consider whether it makes sense because:

a) it's definitely feasible and affordable once needed and compared to flooding costs

b) whatever eventual downsides could be and considering that the dam would not be hermetic
...(not entirely closed but able to let water through into both directions) the benefits would be huge
...once we put the number of cities and infrastructure into account. after all the coastline that would
...be protected with kind of a relatively minor intervention, is several thousand kilometers long.

c) the number of countries to contribute in their own interest would be huge ( affordability)

of course some would argue that they won't follow up adolfs dreams of "atlantropae" ever ;) [JK]

Terrible idea. Once the dam is in place you will have hundreds of millions of people at risk of death in case of a catastrophic failure, dependent on continued maintenance forever after, even in case of major war, civilizational collapse, need for expensive refurbishment and whatever not, not to mention vulnerable to major terrorism or bombing.
It will be the Mosul Dam a hundred times over.
The good news being that by the time humanity realizes the imminent total loss of all coastal cities and infrastructure, there will not be enough cooperation and resources left to attempt such a project. (The same applies to geoengineering).
Another point - damming Gibraltar will raise global sea level faster. Will America, China, India, Northern Europe sit idle? No way.

Think of the cable news ratings from the dam collapse -- the ad dollars alone would pay for construction. Sounds like an argument to build, baby, build!
