Register for the below online courses in HEC-RAS:

This webinar demonstrates the use of rain-on-grid modelling in HEC-RAS, including theoretical background, common practices for model adjustments and improvements to infiltration and roughness parameters that are under development and the additional capabilities they will provide in future versions of HEC-RAS.

Topics covered includes:

  • Basic demo or animation of a rain on grid setup and results
  • Discussion of rain on grid principles and how it’s conceptually different from regular flood modeling (roughness, tolerances, sheet flow paths, etc.)
  • Introduction of what’s coming in 5.1 to improve rainfall-runoff modeling in HEC-RAS (infiltration, spatially varying patterns, etc.)
  • Where the industry is heading with using hydraulic models as rainfall-runoff models (gridded radar data, etc.)
