Description

The U.S. Geological Survey’s (USGS) Multi-Dimensional Surface-Water Modeling System (MD_SWMS) is a pre- and post-processing application for computational models of surface-water hydraulics, morphodynamics and habitat assessment. Its development is an ongoing effort of the USGS National Research Program. MD_SWMS is designed to be generic, allowing the user to choose an appropriate model for their application from a suite of available models while working within a common model-independent framework. In this talk we will provide an overview of MD_SWMS’s capabilities, which include the development of topographic data sets from raw survey information, the interactive development of structured and unstructured coordinate systems, and visualization of model inputs and outputs in two- and three-dimensions. To illustrate these capabilities and the use of MD_SWMS on interdisciplinary problems, three example applications will be described: white sturgeon spawning behavior and habitat assessment in the Kootenai River, Idaho; bridge scour application that includes time-dependent morphodynamic evolution on the Knik River, Alaska; and a simple analysis of fish habitat assessment in the Green River, Utah. We’ll also briefly discuss future model additions including the unstructured finite volume model SToRM, and the large eddy simulation model, H2KE. MD_SWMS is freely available (http://wwwbrr.cr.usgs.gov/gstl/project-MDSWMS.html) and both the interface and modeling software are open-source.
