Discussion: Pair Of 70-Year-Old Reservoir Dams In Houston Overflow Amid Harvey

Houston and southeast Texas is now a humanitarian and national security crisis. Time call for UN assistance?

Donald wants nothing to do with the UN, those silly fools believe in climate change! Maybe Putin will offer assistance.

“Good luck to everybody,” Trump said on the way to the Marine One
helicopter for a weekend trip to the Camp David retreat. “They’re going
to be safe. Good luck to everybody. Good luck.”

Nawww… Trump has it in hand. Everyone’s going to be safe.

Water in the Addicks reservoir exceeded 108ft (32.9m) on Tuesday, geological data shows, causing it to flow over the top of defences.
Officials said the overspill could cause further flooding in nearby communities but the exact impact was unknown.
"This is something we’ve never faced before, so we’re trying our best to wrap around what exactly this water is going to do," Jeff Lindner said.

This is a really scary statement.

And will the overflow cause a hole to start? 70 years ago they may have over built it but probably not with that long a life and subject to flow over the top.

Hard to say. When we almost lost Glenn Canyon Dam in 1983, the BOR was down to erecting plywood panels along the crest of the Dam to keep it from spilling over. Luckily, the waters receded. Otherwise, the dam would have gone.

And although that helps keep flow from eroding the top you’re adding to the pressure. Tough call.

Infrastructure bill? Can we get an infrastructure bill now, please? Bueller?

It wasn’t the top, it was the sides. Water flowing around the sides would have eroded out the sandstone adjacent to the abutments. The dam is set into erodible sandstone. Glenn Canyon dam leaks like a sieve and they have to stabilize the abutment rock with rock bolts. Rock spalls off regularly.

A catastrophe waiting to happen.

Didn’t know that. That is pretty damn scary.

That infrastructure thing sounds like a real good idea, but it can wait until Democrats get back in power.
We desperately need dams, bridges, roads, airports, rail roads, water supplies, a new power grid, schools, hospitals, waste treatment plants; and what do republicans build? Prisons, lots of prisons.

If only.

If only we had someone who could seize this moment to marshal the resources and rally the nation around the urgent need to do this vital work, and use his/her powers of persuasion to convince the legislative body of the stimulative effect of this necessary work and reassure the donor and investor class that these massive expenditures will also benefit them through job creation and a revitalized middle class with purchasing power.

That person is the president. We used to have one of those.
