Floods
« on: April 13, 2017, 05:44:09 PM »
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.

This used to go in the Weird Weather thread, but I see no harm in a thread of its own. So, thanks for opening, Archimid.

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.
