I work for the Corps of Engineers out of Louisville, and I am performing a dam break analysis for one of our reservoirs with Boss DAMBRK and RiverCAD. The purpose of the model is to quantify downstream damages/loss of life expectancy in the case of dam failure. I'm having problems importing more than one DEM at a time into RiverCAD. It takes nearly twenty 30-meter DEM's to cover the downstream area, and I need to be able to import them, merge them, and create contours to be used to cut X-sections with.

Any help would be appreciated.

Thanks.
