Introduction to Hydrologic Modeling Using Geospatial Information: Download

The field of hydrology experienced its most dramatic period of development from the late 19th century to the mid-20th century. While the theory and equations used to estimate watershed runoff have remained relatively unchanged since that time, the availability of Geographic Information Systems (GIS) software and geospatial data has modernized the methods used to evaluate watershed characteristics and develop input parameters.  Today’s hydrologic engineer should understand the advantages and disadvantages of using geospatial data to support hydrologic analysis, recognize the type of spatial data that is available and needed for such analysis, and be aware of the steps required for building a hydrologic model based on geospatial data.

This webinar will provide an introduction to the application of geospatial information to hydrologic analysis.  After participating in the webinar, attendees should be able to:

• Understand what Geographic Information System can do
• List some advantages and disadvantages of GIS
• Understand the importance of datums, coordinate systems and projections
• Describe how GIS can be used to support watershed modeling
• Describe how HEC-GeoHMS can be used to develop a watershed model

Arthur C. Miller, Ph.D., DWRE

Distinguished Professor Emeritus

Dr. Miller is a nationally recognized expert in hydrology, hydraulic engineering, dam safety, and water resource management. His over 40 years of experience includes research, consulting, and publishing in hydrology, hydraulics, floodplain delineation, dam safety, bridge scour, river mechanics, sediment transport, and impacts of climate change. He is renowned for his expertise in numerical modeling of open channel flow; unsteady flow; hydraulic design techniques for dams, bridges and culverts; river mechanics; and sediment transport.  Dr. Miller teaches courses throughout the country on topics ranging from fundamental hydraulics to open channel flow to hydrologic processes. He regularly teaches courses for the National Highway Institute, Association of State Dam Safety Officials, Federal Energy Regulatory Commission, and Federal Emergency Management Agency.
