2025 HEC-HMS- Virtual

Participants will gain a practical knowledge of methods for simulation of runoff from storm rainfall.  The methods covered relate to the processing of historical and hypothetical (design-storm) rainfall data; estimation of losses (infiltration); transformation of rainfall excess to direct runoff with unit hydrographs; routing of flood waves; calibration of model parameters; and modeling of runoff from watersheds.  Experience will be gained in applying the methods with the program Hydrologic Modeling System (HEC-HMS).  Where possible, applications will emphasize hydrologic computations for dam safety.

Key takeaways/learning objectives attendees will receive from this course: 

1. Methods to simulate runoff from storm rainfall.

2. Estimating hydrologic abstractions and transforming excess rainfall using unit hydrograph theory  

3. Evaluating dam and reservoir performance during flood events.

4. Running the HMS model on several real-world problems  

5. Estimating uncertainty in modeling runoff
