Floods

I did a search and couldn't find a floods topic in the consequences section. If there is one, my apologies.

That said:

How can Peru prepare to withstand more devastating floods and landslides?

https://www.theguardian.com/global-development-professionals-network/2017/apr/13/peru-prevent-floods-landslides-climate-change

Extract:
More than 100 people have died, nearly 158,000 are displaced and 210,000 homes are damaged, according to Peru’s emergency operations centre. The country’s infrastructure took a big hit: 260 bridges collapsed and nearly 3,000km of roads are unusable, cutting off hundreds of villages and towns.

Flooding Leaves Millions Without Water in Santiago, Chile

https://www.nytimes.com/2017/02/27/world/americas/santiago-chile-flooding-mudslides.html

Extract:
The mudslides and floods in turn contaminated the Maipo River, a main source of drinking water for much of Santiago and the surrounding metropolitan region. The water utility Aguas Andinas, whose plants draw from the river, suspended service on Sunday for about 1.5 million customers, affecting a total of about five million residents.

Thanks Wili


Where I'm at no more floods is the new norm. Spring flood here had been a yearly occurrence.
Ice would break up, form dams, and downtown was accessible by canoe or rowboat.


Today the river doesn't freeze over, There hasn't been a week in ten years that I haven't seen my grass, and millions of dollars worth of flood control infrastructure goes unused.


I spoke with an archaeologist who was working a Pre-Columbian site a few miles down the river close to the present riverbanks. It had never been flooded until settlers cleared the forests and drained the swamps. Perhaps, in this one instance we're returning the river to it's former state.


But at what a price.

The Ottawa River is flooding extensively. It is clearly at record heights as evidenced by water over topping a retaining wall at the almost completed new hydro electric generating station built in Ottawa. Structures like that are designed for expected high water conditions and it wasn't sufficient. The red arrow in the photo points to where a wall should have been 5+ feet above the water level.

They used the excavator to pile fill to keep the water out and move the shoreline that was eroding back.

Climate change -- and overbuilt levees, and land-use changes -- have led to multiple recent floods around St. Louis, Missouri.

Two catastrophic floods in less than two years wasn't just a case of bad luck
Residents of waterlogged communities along the Meramec River and other swollen area waterways have experienced something unusual for the region.

In a span of just 16 months, the people of cities like Eureka, Pacific and Valley Park have twice braced for and dealt with so-called “100-year” floods that have left damage, financial loss and heartache in their wake. Now, as the floodwater recedes in some communities, residents are left wondering how soon the next catastrophic flood will arrive.

Urban flood mitigation in Tokyo.

G-Cans Project, Tokyo – Japan’s $2.6 Billion Flood Tunnel
The Metropolitan Area Outer Underground Discharge system was built to handle flooding from monsoon-season typhoons, not storm surges from the ocean, and has been used over 70 times, says Takashi Komiyama, head of the pump station. He adds that the system has proven itself effective, reducing damage in terms of the number of homes and area flooded by two-thirds.

cross post:
So much for the seed vault being built for eternity...  :-\

Arctic stronghold of world’s seeds flooded after permafrost melts

https://www.theguardian.com/environment/2017/may/19/arctic-stronghold-of-worlds-seeds-flooded-after-permafrost-melts

Abstract:
"It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.

The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”.

But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. “It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that,” said Hege Njaa Aschim, from the Norwegian government, which owns the vault."

Arctic ice is healthy for children and other living things.

Why Rains and Flooding Are Plaguing America
- Weather pattern pumped moisture across U.S. throughout season
- Warmer Gulf of Mexico waters allowed storms to recharge
To understand why heavy rains and widespread flooding have plagued the U.S. this spring, go to the Pacific Ocean.

Last winter, a pool of cool water set up next to a warm patch across the northern Pacific, said Paul Pastelok, lead long range forecaster at AccuWeather Inc. in State College, Pennsylvania. “This led to an avenue for storms that came off the East Asian coast. Instead of dying out, they traveled along that avenue and maintained their strength.” It’s the same phenomenon that delivered a warm winter and ended California’s unprecedented drought....

How Rising Seas Drowned the Flood Insurance Program

http://www.climatecentral.org/news/how-rising-seas-drowned-the-flood-insurance-program-21484

Extract:
Recently, the U.S. Army Corps of Engineers pumped more than ten million cubic yards of sand from offshore dredges to widen Long Beach Island’s beaches and dunes – part of a Sisyphean-like effort to protect the island’s $15 billion of high-calorie real estate. But there is a problem. The sand keeps washing away. A series of storms over the last two years gouged the neatly groomed beaches, costing tens of millions in additional repairs. When all is said and done, the project will cost more than half a billion dollars, most of the money paid by U.S. taxpayers.

Fighting against the sea in such a manner is sheer idiocy. At such costs, it is the very definition of unsustainable, especially given accelerating sea level rise. Sometimes you just have to cut your losses, the earlier the better.

I agree. I think their experience tells them that this too shall pass, as it always have. They think they just have to ride the rough times and then things will get better.  In this case that experience is our worst enemy because with SLR and CC this is only going to get worse.

At least for now, global sea level rise continues it's multi decade pattern of reverting to the trend of 3+ mm of rise per year. https://www.aviso.altimetry.fr/en/data/products/ocean-indicators-products/mean-sea-level.html  After a big jump in late 2014 and 2015, there has been a decline in global sea level over the past two years. Will we get a bounce back year with an unusually large rise in sea level during the Trump administration, and a related increase in sunny day flooding?

Given how big a "nuisance" sunny day flooding is already, how severe will the problem become if we get a couple of years of abnormally large increases in sea level rise? How much deeper underwater will the National Flood Insurance Program (NFIP) get once sea level begins to rise again

Cyclone Mora: Bangladesh tries to evacuate one million
Bangladeshi authorities are trying to evacuate up to a million people before a powerful cyclone makes landfall.

Cyclone Mora is likely to hit the eastern coast early on Tuesday, the meteorological department said.

Port cities in the south-east have been asked to display the highest warning system known as "great danger level 10". Ports further west are on level 8.

The cyclone formed after heavy rains in Sri Lanka caused floods and landslides that killed at least 180 people.

The worst flooding in 14 years on the island has affected the lives of more than half a million people. More than 100 people remain missing....

"The monsoon rains are the the worst to hit Sri Lanka since 2003. They come after two months of drought, which had grown severe enough to warrant aid from the World Food Programme."

Sri Lanka floods: Battle to rescue stranded as death toll mounts
(CNN) Severe flooding brought on by monsoon rains across southwestern portions of Sri Lanka has resulted in the deaths of at least 169 people, according to the country's Ministry of Disaster Management.

As many as 112 people are still missing, and the death toll is expected to rise, as authorities battle to rescue those still stranded and warn of the possibility of crocodile attacks.

"It was only the next morning that troops arrived in boats, and took us to safe ground," Banakiyanage Gnanawathie, who lives in the badly hit town of Matara, told CNN by phone.

"I have never seen such floods though I have spent my entire lifetime in Matara. We have lost all our belongings and remain in the clothes we wore. I am still happy we escaped the floods and even the crocodiles," she said.

She said that they won't be able to return home for days.  "There is only a roof and building. We have lost everything else."

The heavy rain occurred over a very short period of time, leading to the displacement of 112,000 people, according to Pradeep Kodippily, spokesman for Sri Lanka's Disaster Management Center. Almost half a million people have been affected by the flooding.

The bout of severe weather has also triggered landslides throughout the country.

The southern coastal city of Galle has seen 223 millimeters (8.78 inches) of rainfall over the past 48 hours, and Ratnapura, further inland, has experienced 453 millimeters (17.8 inches) of rain over the same period.
