Arc Hydro is a community, data model, set of tools, and workflows to support the GIS side of hydrologic and hydraulic (H&H) analyses. Learn how to apply the Arc Hydro data model while running workflow-driven tools in a watershed modelling application. Starting with a good quality digital elevation model (DEM), you will conduct terrain preprocessing to hydrologically condition the DEM. The next step will involve input into stream drainage network identification, followed by catchment delin...
