Course Information

Name:Use of HEC-RAS 2D for Disaster Preparation and Response

New Course:No

This presentation will demonstrate various techniques and considerations for utilizing the 2D modeling functionalities of HEC-RAS 5.0x for modeling large, complex areas for flood inundation and forecasting activities.


Specifically, the presentation will focus on ways in which these techniques can be used to assist municipal agencies in resource staging and dissemination before, during and immediately after a storm event.


  • Discuss internal and external data requirements for executing rain-on-grid modeling
  • Demonstrate use of refinement regions and breaklines to gain computational mesh detail or maximize computational efficiencies
  • Discuss the usage of inflow hydrographs to minimize the extent of the computational area where possible

No upcoming dates for this course.
