Surface-water Modeling System (SMS)

The Surface Water Modeling System (SMS) is a comprehensive environment for one- and two-dimensional models dealing with surface water applications. Hydrodynamic models include CMS-Flow, ADH, FESWMS, ADCIRC, 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 and sediment transport (FESWMS). Wave models in SMS include CMS-Wave, STWAVE, BOUSS2D, and CGWAVE and include both spectral and wave transformation 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.
