Get as many cores as you can afford, but not at the expense of processor speed. But for large numbers of cells, you’re going to want as many cores as you can get your hands on. “All Available” may not necessarily be the fastest. For smaller datasets, I suggest experimenting with this to optimize computation speed. Fortunately, HEC-RAS has an option to change the number of cores you wish to use in the Computation Options and Tolerances window (from the unsteady flow analysis window…Options…Calculation Options and Tolerances…2D Flow Options tab). The reason behind this is that there is a level of computing overhead used just to transfer data between cores. less than 10,000 cells or so), 8 cores may indeed run slower than 4 or 6 cores. In fact, it has been found that for smaller 2D areas (e.g.

More processing cores is not always better.

WEST has developed numerous stand-alone and HEC-RAS supporting software including WinXSPRO, WEST-EDI, and the RIPRAP Design System. WEST is a contractor to the USACE Hydrologic Engineering Center (HEC) and is the on-site HEC-RAS instructor for the American Society of Civil Engineers (ASCE). WEST Consultants is internationally recognized as an expert on HEC-RAS, with extensive experience applying HEC-RAS to thousands of projects on behalf of the United States Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), the Federal Highway Administration (FHWA), the Federal Regulatory Commission (FERC), and many other federal, state, and local clients.

Manning’s roughness (channel and overbank).

SimRAS is applied risk assessment. By directly simulating the probability distributions for all key parameters, risk analysis of dams and levees can be rapidly determined, allowing risk-based floodplain mapping that accounts for every identified uncertainty and is easily shown through standard mapping procedures. SimRAS is optimized for levee and dam breach studies, with work currently underway to extend the capabilities to simulate all types of river models.

The results will be used to reassess the hazard classification of the dam. WEST worked with the Federal Energy Regulatory Commission (FERC) to define the breach outflow parameters and then used SimRAS to successfully map the 1% flooding risk by rapidly computing thousands of different, randomized scenarios. Recently, WEST Consultants used SimRAS to complete a probabilistic breach outflow analysis on a major dam in Montana. Truncated distributions fully supported.Utilizes HEC-RAS standard database (HEC-DSS) for all parameter and results storage.Python based program allows easy modification to individual projects.Instant results reporting through dynamic tables and figures.Facilitates statistical distribution type and parameter selection with dynamic plots.Easy-to-use GUI interface minimizes learning curve, allowing efficient, error-free simulations.When complete, the results can be used to determine the risk of a particular event occurring, evaluate parameter sensitivity, and/or determine most likely outcomes. Completely automated, SimRAS runs the HEC-RAS model multiple times, selecting randomized values of the key parameters for each run (consistent with a Monte Carlo analysis). It allows the user to assign a statistical distribution to one or more key parameters in the chosen HEC-RAS 1-D or 2-D model. SimRAS is a multipurpose HEC-RAS simulation tool with a simple graphic interface.
