Stream and catchment delineation with GIS theory

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=ZLUjSEK-nbg

This video show how to derive streams and catchments from a DEM using geographic information systems (GIS). The whole workflow will be presented, which includes, DEM aquisition, mosaic, reprojection, void filling, filling of sinks, Strahler order, D8 flow direction and much more. • This video is part of IHE Delft OpenCourseWare.
