2021 Fall Workshop Series

Reviewing HEC-RAS 2-D Models: Pretty Colorful Animations are Not Always Accurate - Wed, Nov. 3, 10:00 am - 3:00 pm MST, Eligible for 4 PDHs

For past five years, the H&H community is delighted to use HEC-RAS 5.0 and its subsequent versions, which are public domain, free, and meticulously tested software from HEC and include fully 2-dimensional (2-D) and combined 1-dimensional (1-D) and 2-D unsteady flow modeling in addition to its traditional 1-D modeling capabilities.  In this period, use of HEC-RAS for 2-D modeling has increased exponentially.  HEC-RAS version 6.0, released in May 2021, has many added capabilities and features over previous versions including faster speeds, variable time step, and pre-processing tools.  This will attract even more users using this software.  There are many advantages of using a 2-D HEC-RAS model, including the ease with which a 2-D model can be set up. Does that mean all 2-D models that run and provide results are justified and correct? That is the most important question when tasked with reviewing a 2-D model. This workshop will discuss good modeling practices and identify common mistakes that are overlooked in creating a 2-D HEC-RAS model.  The workshop will include a live interactive demonstration of HEC-RAS 2-D during which participants will play a reviewer’s role in finding model problems.  This workshop is not intended to teach attendees how to use HEC-RAS 2-D; instead, it will focus on providing information for those who review HEC-RAS 2-D models. The workshop will also cover best practices for conducting dam breach analysis and discuss new pre-processing and advanced modeling features of HEC-RAS version 6.0. All participants will receive a checklist for HEC-RAS 2D model reviews.

This workshop will be of interest to Engineers, H&H modelers (all levels), government employees (model reviewers), dam owners.

Eligible for 4 PDHs
