I know that a theory has often been brought up that .... if a levee system increases the volume of a section of the river, then it will scour the channel, keeping it clear. But I thought that civil engineers could not prove it, and the theory has always been dismissed. Aren't levees for flood protection, and dredging for navigation?" No, I wasn't thinking about that at all, I was thinking about River meander and that levees because of flood control keep the river in course. For those interested, here is a nice short history on levees, and river control: [url]http://mshistory.k12.ms.us/features/feature25/msriver.html[/url] Also, here is a link to the Army Corp of Engineer's site: [url]http://www.usace.army.mil/[/url] Jim
