This session will provide a foundation for performing flood and hydrologic analysis with ArcGIS. We will build from the foundational tools and workflows through to web application examples. We will explain the principles behind the hydrologic tools in Spatial Analyst and the Arc Hydro toolbox and use those to derive a variety of hydrologic datasets for hydro landscape characterization. The demonstration will then provide an overview of hydrologic, and hydraulic modeling, and how to use ArcGIS to map future flood risk, concluding with flood mapping web application examples you can customize.
