HEC has released a new HEC Research Document called “Benchmarking of the HEC-RAS Two-Dimensional Hydraulic Modeling Capabilities”.  This research document summarizes how the Hydrologic Engineering Center’s (HEC) River Analysis System (HEC-RAS) software performed in the two-dimensional (2D) modeling benchmark tests developed by the United Kingdom’s (UK) Joint Defra (Department for Environmental Food and Rural Affairs) Environment Agency.  These Benchmarking Tests are widely used to compare 2D models over a wide range of flow situations.

Here is the link to the document on the HEC-RAS web page:

Please foreword this post to anyone you know that would be interested in this document.
