Hydrologic Modeling with GSSHA & WMS

Course Description

The 2D hydrologic modeling course begins with an overview of the hydrologic modeling capabilities available in the Watershed Modeling System (WMS). In the course, you will learn about the US Army Corps of Engineers Gridded Surface Subsurface Hydrologic Analysis (GSSHATM) model. GSSHA is a 2D hydrologic model that can be used to model basic watershed rainfall/runoff processes. GSSHA can also be used to model more advanced watershed processes. This course will introduce how to set up basic and advanced GSSHA models using WMS. You will also learn about a lot of the cutting edge post-processing tools available in WMS.

Course Outline - 4 Days

  • Learn about images and coordinate systems in 2D hydrologic modeling
  • Use geographic information system (GIS) vector data, elevation data, and other spatial data to create and parameterize the 2D hydrologic models
  • Easily obtain spatial data using web services
  • Delineate watersheds and gridded models using data obtained from web services
  • Modify basic GSSHA models to include more advanced watershed process such as land use change scenario modeling, wetland hydraulics, sediment erosion/deposition, spatially varying precipitation (RADAR rainfall), long-term simulations, regional-local model linkages, overland flooding scenario modeling and groundwater flow simulations
  • Learn about resources available to help you learn more about GSSHA and WMS

Course Requirements

Participants may be required to provide their own computer with the following specifications:

  • Windows XP, Vista, 7 or 8 operating system
  • 1 GB RAM (2 GB recommended)
  • CPU: GMS software is CPU intensive. Some models and utilities such as Parallel PEST can take advantage of multiple processor cores simultaneously.
  • Graphics Card: For all display features to be enabled, OpenGL 1.5 or higher must be supported. The use of a dedicated graphics card is strongly recommended. Integrated graphics can result in significantly reduced performance and may not support some visualization features.
  • 1024x768 resolution (1280x1024 or higher recommended)


To be announced


Attendees should fly into the Salt Lake International Airport (SLC), then drive, take a taxi or schedule a shuttle.
