Gridded Surface Subsurface Hydrologic Analysis (GSSHA) Model Training for EWN Project Design

Multi-day Event (September 6-
7, 2023)

Purpose

This training event took place on 6-7 September 2023 in Norman, Oklahoma, sponsored by the U.S. Army Corps of Engineers Hydraulics and Hydrology (H&H) Set and the Engineering With Nature Program.

The training workshop introduced the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model and the Department of Defense Watershed Modeling System (WMS). Instructors included the GSSHA developers Drs. Aaron R. Byrd, Charles W. Downer, and Nawa Pradhan USACE-ERDC, Dr. Chris Smemoe from Aquaveo, and GSSHA application expert Mr. Stephen J. Turnbull USACE-ERDC.

This course was intended for anyone interested in watershed hydrology as it relates to design of EWN projects. Experience with hydrologic modeling and numerical methods are a plus, but not required. Some college-level background in hydrologic science and/or engineering is required.

Students learned the basics of:

  • Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model, developed at the U.S. Army Corps of Engineers, Engineering Research and Development Center and the University of Wyoming
  • Dept. of Defense Watershed Modeling System (WMS), developed by Aquaveo LLC
  • Spatial data needed to estimate distributed GSSHA model parameters, including data requirements, basics of GSSHA/WMS and how to find and use spatial geographic data to develop GSSHA models using the WMS Hydrologic Model Wizard.
  • How to utilize GSSHA and WMS to design EWN projects.
