Boundary and Initial Conditions for 2D Flow Areas Running a Model with 2D Flow Areas

HEC-RAS has a 2D flow area pre-processor that processes the cells and cell faces into detailed hydraulic property tables based on the underlying terrain used in the modeling process.

Using HEC-RAS to perform 2D modeling or combined 1D/2D modeling is very easy and straight forward. The following are the basic steps for performing 2D (or combined 1D/2D) modeling …

The HEC-RAS website provides a number of resources, which include helping the user download software, learn how to use HEC-RAS, resolve problems, report bugs, and suggest …

The home page contains User's Manuals, Hydraulic References, Application Guides and more covering topics in 1D, 2D and sediment hydraulics. This documentation can also be accessed …

The HEC-RAS 2D computations will use as many CPU cores as there are available on the user’s machine (which is the default mode for running). However, HEC-RAS provides the option to …

HEC-RAS has been developed for the U.S. Army Corps of Engineers (USACE). However, software developed at the Hydrologic Engineering Center is made available to the public …

Two Dimensional Flow Areas (2D Flow Areas) are regions of a model in which the flow through that region will be computed with the HEC-RAS two dimensional flow computation algorithms. …

In this workshop, you will learn how to create how to generate a 2D Mesh within a 2D Flow Area with HEC-RAS. This workshop will require you to use import a terrain model, develop a 2D …
