HEC-RAS 5.0 2D Modelling Course

This intensive course will prepare the engineer or water resource professional to use the newly released HEC-RAS 5.0 software for modelling two-dimensional (2D) flow. The course curriculum is an intensive combination of lectures and workshops focussed on 2D model development in HEC-RAS. All electronic and printed course materials are provided under license agreement with WEST Consultants, a contracted U.S. Army Corps of Engineers training provider.

Our inaugural Melbourne course was taught by former HEC programmer and code writer Chris Goodell, a highly regarded expert in two-dimensional modeling whose experience includes code writing and model development for the U.S. Army Corps of Engineers Hydrologic Engineering Centre. Additional courses across Australia will be taught by Krey Price, a widely experienced hydraulic modeller who spent fifteen years of his career developing hydraulic models for the U.S. Army Corps of Engineers. Krey has recently completed and presented benchmarking studies comparing the results of HEC-RAS 5.0 2D models to TUFLOW for Australian river systems.

This course assumes a rudimentary prior knowledge of one-dimensional HEC-RAS model development. The course is intended to prepare participants to construct, run, view, and interpret 2D models and combined 1D/2D models for unsteady flow conditions and will provide an introduction to sediment transport capabilities within HEC-RAS. All attendees build, run, and animate a 2D model from scratch by the end of the course.

All course days run from 8:30 am to 5:00 pm. Following is an outline of the course proceedings:
