HEC-RAS 1D-2D Course in Atlanta

Hey RAS Users-

This is a "Save the Date" notice for an upcoming 1D-2D HEC-RAS 3-day training course I'll be giving in Atlanta on May 7-9, 2019.  We'll be covering everything from setting up a 2D model, a 1D-2D combined model, RAS Mapper pre- and post-processing, viewing output, river restoration, to dam/levee breaching.  The class will consist of a mix of informative lectures focusing on practical aspects of 1D-2D HEC-RAS modeling and interactive exercises.

Come join me for a great opportunity to learn the tricks of 1D-2D modeling in HEC-RAS and to network with fellow HEC-RAS Users.

If you are interested, please follow the following link and express your interest.  We will send more details, including the venue and registration instructions as soon as they are available.

  1. Hi Chris;
    I am wondering if you have or will be considering holding your 1D-2D HEC-RAS course as a online webinar? It would potentially be useful for users who cannot attend the 3 day training course. Let us know. Thank you

  2. Hi Chris,

    You presented a course on HEC-RAS 2D modelling earlier this year (March, at the University of Pretoria) and I would like to ask for more information regarding performing a dam break analysis on a concrete arch dam. I've realised most information is on earth dams. We have been tasked, as students, to perform three dam break analysis. I have read that overtopping is unlikely to cause a concrete arch dam to fail so in HEC-RAS that leaves us with failure due to piping. How would one analyse failure due to erosion of the foundation/abutment, abutment sliding or seepage? Also is it correct to use a 2D mesh for the reservoir as well as the flow of water downstream while the dam is a '2D Area Connection' and the inlet and outlet 'SA/2D Area BC Lines', therefore I wouldn't have to use a mix of 1D and 2D?
