SMS is better than ever with the new features added to v11

1. New Raster Module
   • Work with raster (DEM) data in SMS without converting to a scatterset (TIN)
   • Raster data require less memory and draw faster than TIN data
   • Interpolate raster elevations to a scatterset, mesh, or grid
2. ADH Model Interface
   • SMS seamlessly interfaces with the 2D shallow water component of the US Army Corps Adaptive Hydraulics Modeling system (ADH)
   • Key features of the ADH model include wetting/drying of elements, boat effects, wind effects, and an adaptive mesh, where element resolution is dynamically adjusted as needed
   • The ADH interface in SMS was developed in collaboration with the Coastal and Hydraulics Laboratory at the USACE Engineer Research and Development Center
3. WAM Model Interface
   • WAM is a third generation wave model that predicts directional spectra as well as wave properties such as significant wave height, mean wave direction and frequency, swell wave height and mean direction, and wind stress fields corrected by including the wave induced stress and the drag coeffieient at each grid point at chosen output times
   • Build WAM grids, create simulations, nest grids, view solutions, and generate spectra for STWAVE model input
4. Bouss2D Run-up & Overtopping
   • Run Bouss2D in 1D mode to simulate run-up and overtopping of waves
   • Extract transects, position gages, specify roughness zones, and define multiple wave cases
   • Create 2D profile plots along transects, time-series plots of gage output, and generate summary statistics such as height of peak waves within a percentile range and the point of furthest encroachment on each transect
5. TUFLOW Advection-Diffusion Module
   • The new TUFLOW AD Module is fully supported by SMS
   • TUFLOW AD simulates depth-averaged, two and one-dimensional constituent fate and transport
   • Simulate both dissolved and particulate constituents
   • Create spatially varied initial concentrations and transport coefficients
6. Generic Model Interface Enhancements
   • Boundary condition and material property templates have been expanded to include more data types
   • Assign multiple boundary conditions to a single node, element, or nodestring
   • Create templates that show/hide parameters based on a selected option
   • Define multiple material groups
7. CMS Model Updates
   • Couple of flow and wave models without the steering module using the CMS inlined version
   • Implicit solution scheme in CMS Flow allows for larger time steps and parallel computing across multiple processor codes..
   • CMS wave new features include muddy bed definition, non-linear wave effects, infragravity wave effects, spatially varied wind field, XMDF output, and a Gauss-seidel solution scheme which utilizes multiple processor cores
8. TUFLOW Model Updates
   • Import TUFLOW projects created outside of SMS
   • Output datasets to XMDF
   • Create and manage irregular culverts
   • New manhole features
9. STWAVE Model Updates
   • Support for the new STWAVE v6.
   • Extract boundary conditions from a WAM model
   • Improved iteration control for the full-plane version
10. Particle Module Updates
    • Estimation guidance for the number of particles that will be generated by a PTM source coverage
    • Create virtual gages to compute concentrations and other data around a point or within a polygon
    • Use particle filters to display a subset of particles to use for display, selection and compute grid datasets
11. ArcGIS Map Server Layers
    • With a license to ArcGIS and an internet connection, utilize ESRI's database of maps and open ArcGIS map server layers in SMS
    • Background maps are updated on-the-fly as the display is zoomed and panned
12. Other New Features
    • Assign native projections to cartesian grids and project grids on-the-fly to the working projection.
    • SMS now saves a world file and projection file if appropriate when saving the graphics window as an image file
    • Export mesh elements to a shapefile using the Mesh->Map command
    • Import TINs from LandXML files
    • Use the "Zoom to..." feature to easily zoom to the extents of a mesh, grid, scatterset or bounds of selected objects
