Basic Hydrology ArcMap Edition

Soil and water district technicians will learn how to model small watersheds for conservation and stormwater management structures. Three hydrological models are presented: EFH2, TR-20/TR-55, and the rational method. A blend of GIS and by-hand analysis methods are shown. EFH2 software is presented for rural problems while HydroCAD is used for urban projects. The course culminates in a design example to allow students to implement what they've learned.
