On-Demand Webinar: Introduction to Hydrologic Modeling Using Geospatial Information
Association of State Dam Safety Officials, 2015
This webinar will provide an introduction to the application of geospatial information to hydrologic analysis. 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.
Key Take-aways:
- Understanding of Geographic Information Systems.
- Advantages and disadvantages of GIS.
- Understanding of the importance of datums, coordinate systems, and projections.
- Knowledge of how GIS can be used to support watershed modeling.
- Understanding of how HEC-GeoHMS can be used to develop a watershed model.
