spillway

The problem with the old spillway was, that it was just put on top of the soil.

We have a spillway with same beaver situation.

If they’d cut down that one tree in time we probably would still have the original spillway.

There is all reason to assume that this new spillway will hold up much longer than the old one, which did work for 50 years.

On top of that they built the new spillway, up to modern standards and much thicker than the original one.

The new spillway may outlive the life of the containment structure its designed to protect.

The line is shut down right now because the flood relief spillway is open near New Orleans and water might possibly swamp the trestle.

As a side note, I watched this channels videos of the spillway failure, and then randomly a very good video of the 737-max debacle.

I think in someone else's link there was a figure about the rejected 2005 improvements to the emergency spillway being $100M.

The flood of feelings and nostalgia are beginning to creep over the spillway of my hastily constructed dam.

Over the decades, the soil got eroded away by water in some places, destabilizing the spillway.

Large parts of the spillway had to be replaced in a couple of months, laying enough concrete to build a pyramid - I have to look up the exact numbers to see how large exactly.

While it was being repaired, historic levels of monsoon rains flooded the reservoir behind it, requiring the use of the spillway at volumes it was not designed to handle.

In Ontario, Canada, if the plant doesn't run at capacity, generally the water is sent through the spillway without generating power.

Given that, there's no reason to suspect that upgrading the spillway prior to failure would have seemed like a higher priority than many other remediation projects.

To see what modern technology can achieve, look at modern construction sites, like skyscrapers or especially the work done at the spillway of the Oroville dam after it broke.

There was not an a priori way of knowing it was going to fail, instead of a bridge abutment or whatever else was presumably repaired first, and would have had to wait if the spillway work had happened first instead.

The end of the spillway with the enormous waterfall makes me uncomfortable since erosion back from that point working backwards along fissures to undermine the spillway basin seemed to be an aspect of design contributing to the previous failure.

Truly if we were spending on levees and spillways at engineer-recommendations, recent hurricanes and floods would have caused notably less damage [1].I guess my only point is that while I concur that it's careless to try to draw conclusions from this data, I don't think we can clearly assume that progress alone shows us which direction the data is skewed and why.[1] Would we have even had to open the Morganza spillway if Louisiana's levees had been maintained and updated over the years?
