The Surface Water Modeling System (SMS) is a comprehensive environment for one- and two-dimensional models dealing with surface water applications. Hydrodynamic models include TABS (RMA2, RMA4), FESWMS, ADCIRC, CMS-Flow, and TUFLOW. The hydrodynamic models cover a range of applications including river flow analysis, rural and urban flooding, estuary and inlet modeling, and modeling of large coastal domains. Additional functionalities include advection/diffusion (RMA4) and sediment transport (FESWMS). Wave models in SMS include STWAVE, BOUSS2D, and CGWAVE and include both spectral and wave transformational models. The Particle Tracking Model (PTM) tracks particles added to the water column to help evaluate sediment transport and environmental impacts. In addition, the generic model interface allows users to use the powerful mesh building tools with numeric engines that do not have custom interfaces. SMS can import data from a variety of files including text, CAD, and GIS files. SMS contains many visualizations options including contours (filled or linear), flow/velocity vectors, creation of animations, and exporting to Google Earth or GIS.

Product Overview

The numeric models supported in SMS compute a variety of information applicable to surface water modeling. Primary applications of the models include calculation of water surface elevations and flow velocities for shallow water flow problems, for both steady-state or dynamic conditions. Additional applications include the modeling of contaminant migration, salinity intrusion, sediment transport (scour and deposition), wave energy dispersion, wave properties (directions, magnitudes and amplitudes) and others.

New enhancements and developments continue at the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University in cooperation with the U.S. Army Corps of Engineers Waterways Experiment Station (USACE-WES), and the US Federal Highway Administration (FHWA).
