Masonry dam had quite a different problem which is just that there was too much water and it couldn't keep up, so water spilled over the side about 6000ft away from the dam. The problem with the Mosul dam is that it's built on soluble rock that could be swept away with enough pressure. Yes, too much water is the cause of both failures, but they're quite different.
- snowwindwaves 10y agodo you have a better link to information on Masonry dam? My information is second hand from a hydro electric turbine expert. He clearly stated to me that the dam was built in a location that was geotechnically unsuitable so water flooded underground channels due to the pressure of the water behind the dam and popped up all over the place. A nearby lake level raised a bunch. I might have got the wrong link. "masonry dam" is hard to google, as intended.
- mynameisvlad 10y agoHeh, I was originally going to ask you for more information before my comment because the link wasn't the most descriptive on that incident, but briefly mentions that it happened 6000 feet away from the dam, which got me curious. I think had some more luck searching for "Boxley Creek 1918" or "Boxley Burst" which was the name of the actual incident. http://www.historylink.org/File/2426 http://www.historylink.org/File/2426 was the first result on Google.
