This advanced course assumes you understand the fundamentals of HEC-RAS, with 1+ years of experience. We encourage you to complete the HEC-RAS Essentials Course first, as it will prepare you well for the advanced topics we will cover.

Topics covered include:
- 1D vs 2D vs 3D theory for dam breach
- Level pool vs. dynamic reservoir drawdown
- Adding a dam as a 1D reach or inline structure
- Selecting dam breach parameters
- Setting up and running a dam breach model
- Diagnosing and troubleshooting a dam breach model
- Model calibration and sensitivities
- Exporting inundation and flood wave arrival results
