Mosul is hardly an example of a well engineered dam though built in 1984 and falling to pieces. The Hoover Dam was built in 1933 and is not in need of pulling down.
- JoeAltmaier 10y agoIf maintenance were interrupted (social upheaval) then Hoover too would fail. It take maintenance to keep it running - in particular mussels would foul and stop the turbines in a few seasons.
- masklinn 10y ago> If maintenance were interrupted (social upheaval) then Hoover too would fail. Probably not in your lifetime let alone in a generation. Mosul's an issue because the substrate is not suitable for dam building (it's soluble gypsum, so it just keeps eroding because dam foundations kind-of tend to be around water) so the dam has to be continuously grouted to prevent it from failing.

- cr1895 10y agoThey're not really comparable are they? It's not whether the turbines in the dam will continue to generate electricity, but whether or not the dam itself is structurally sound. My limited understanding is that the Mosul dam is not, while Hoover will outlast us.
- dredmorbius 10y agoThe risk in the case of Mosul is failure of the dam face itself. Not merely the generating equipment. Hoover faces no threats of similar magnitude.
