If you are interested in a more detailed dive into HEC-HMS, our HEC-HMS Essentials course covers basic model set up as well as advanced features like gridded rainfall. The course includes three 3-hour sessions with workshop exercises:

• Session 1: Covering data wrangling, GIS delineations, and model setup
• Session 2: Covering the application of gridded rainfall, loss sensitivities, interpreting and calibrating results
• Session 3: Covering the application of Australian Rainfall and Runoff in HEC-HMS using Storm Injector (temporary license provided)

The course is currently available to attend online on-demand. Registration link here. Use coupon code “hydroschool-10” to receive a 10% discount at checkout.
