That's all the more tragic if the purposes for which the dams were built may no longer be served by them. I'm pretty ignorant about engineering so I do not know to what extent either the initial destruction or the long-term effects could have been avoided or mitigated (or to what extent, from place to place, dams were unnecessary or, while necessary for development, arguably should not have been used to sustain development). But if the New Orleans levee system is at all representative, it's not simply a matter of engineering negligence but rather government's refusal to listen to the engineers about what should have been done -- always going for the quick and cheap that will satisfy voters' short-term demands (or those of the lobbyists) with little or no regard for the future -- i.e. anything beyond a few years.kladyhttps://www.blogger.com/profile/09526715552795733402noreply@blogger.comtag:blogger.com,1999:blog-457782610616273742.post-49643008079987763562008-03-09T21:56:00.000-04:002008-03-09T21:56:00.000-04:00As I read about it, the purpose of the release was...As I read about it, the purpose of the release was to allow the buildup of sandbars in the Grand Canyon. This suggests to me that the silt which is not flowing into the Canyon must be building up behind the walls of Glen Canyon Dam. At some point, the buildup will be so significant that the dam will have lost most of its capacity. We have some some dams in California which have lost over 90 percent of their storage capacity in this way. <BR/><BR/>I wonder what will happen then?John D Bassetthttps://www.blogger.com/profile/01716421788208143074noreply@blogger.com
