Clean Dams Tool

Clean Dams

Given an elevation dataset, runs cleandam.exe to remove digital dams, which are depressions where the cell elevation is lower than its four neighbor cells. If a GSSHA boundary conditions coverage containing a stream network is provided, the cells where the streams intersect the grid are not altered. For more information on cleandam.exe, refer to the GSSHA Wiki.
