Instructor: Jeff Harris, P.H.
Course Length: 1 Hour
This webinar provides an overview of the use of gridded radar rainfall in the HEC-HMS software.
Purpose and Background
The Hydrologic Modeling System (HMS) software is a product of the US Army Corps of Engineers' (USACE) Hydrologic Engineering Center (HEC), hence the name HEC-HMS. The latest version is 4.0 and is available directly from the HEC website. It is free of charge to download and use. The latest documentation is also available. The HEC-HMS software is written in general terms so it can be used on a variety of basins. Basins can be large, small, urban, commercial, industrial, wet, dry, etc. It handles channel routing, soil moisture wetting and drying, snowmelt, precipitation, baseflow, diversions, and reservoirs, among many others. Users have the choice to select methods suitable for solving their specific problem. HEC-HMS also has the capability to use gridded radar rainfall to further enhance the computations to take into account detailed rainfall information. This webinar discusses the general aspects of HEC-HMS, then provides details on how to incorporate gridded radar data into the HEC-HMS Meteorological model process.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
