What skills and knowledge will you acquire during this course?During this course, participants will acquire the following skills and knowledge:
1. Computing peak runoff rates for rural watersheds: Participants will learn how to calculate the maximum amount of water that can flow out of a rural watershed during a storm event.
2. Computing peak runoff rates for urban watersheds: Participants will learn how to calculate the maximum amount of water that can flow out of an urban watershed during a storm event, taking into account the impact of impervious surfaces.
3. Delineating watersheds using maps and ground truthing: Participants will learn how to identify and delineate the boundaries of watersheds using both maps and on-site observations.
4. Understanding the differences between the three most widely used hydrology models: Participants will gain a comprehensive understanding of the EFH2, TR-20&TR-55, and rational method hydrology models, including their strengths, weaknesses, and appropriate applications.
5. Creating hydrologic models using GIS: Participants will learn how to leverage the power of Geographic Information Systems (GIS) to create hydrologic models of small watersheds. Parallel workflows will be presented for both ArcGIS (with the Spatial Analyst extension) and QGIS.
6. Utilizing EFH2 and HydroCAD software: Participants will be introduced to the EFH2 software for rural hydrology modeling and the HydroCAD (Free Sampler edition) software for urban projects.
7. Implementing conservation and stormwater management structures: The course will culminate in two design examples, allowing participants to apply their newly acquired skills and knowledge to design and implement conservation and stormwater management structures in small watersheds.

Who will benefit from this course?
This course will benefit soil and water district technicians and junior engineers who are involved in modeling small watersheds for conservation and stormwater management structures. Specifically, individuals who are interested in hydrology and want to learn how to create hydrologic models of small watersheds using GIS will find this course valuable.

The course is designed to teach participants how to compute peak runoff rates for both rural and urban watersheds. It also covers the process of delineating watersheds using maps and ground truthing. Additionally, the course focuses on the three most widely used hydrology models: EFH2, TR-20&TR-55, and the rational method.

The course includes a combination of GIS and by-hand analysis methods. For the GIS portions, parallel workflows are presented for both ArcGIS (Spatial Analyst extension) and QGIS. Participants will also learn how to use specific software such as EFH2 for rural hydrology and HydroCAD (Free Sampler edition) for urban projects.
