General Features


1D Module

  • 1D Module added back into SMS to support HEC-RAS 1D.

GIS Module

Map Module



  • Updates to the ADCIRC interface.
    Note: SMS 13.0 ADCIRC project files should not be imported into 13.1. Instead, use the native ADCIRC files to rebuild the project.




  • Tools available on simulation right-click:
    • Advanced simulation
      • Multiple scenario management
      • Automatic calibration (Parameter Estimation or PEST) using Manning's n and/or flowrates.
    • View Simulation Plots (see new plots discussion)
    • Statistical Analysis
    • Summary Report Generation. Generates an HTML report summarizing contents and attributes of the project. This is designed to be a first pass at model review.
    • Datasets to Rasters
  • SRH-2D specific floodway tools available on simulation right click (New): These are in addition to the general floodway delineation tool available on the 1D centerline coverage.
    • Generate Floodway Simulation: This generates a new simulation and a new boundary condition coverage.
    • Generate Floodway Cross Section: These cross sections can be used to evaluate rise and velocity comparing a floodway simulation to a floodplain simulation.
    • Compare Floodway Simulation Data: This generates a customized cross section summary table to compare water levels and velocities between a floodplain simulation and a floodway simulation.
  • New plots - displayed in the Run Queue as well as accessible in Tools|View Simulation Plots menu command when right clicking on a simulation:
    • Simulation plots:
      • Net Q (Outflow - Inflow)/Inflow
      • Mass Balance. This includes both mass balance for each time step and the cumulative mass balance
      • Simulation plot for number of wet elements
    • Structure plots available when right-clicking on a BC arc for Culverts, Weirs, Gates, and Links
    • Monitor line and monitor point plots available when right-clicking on these entities.
  • New boundary condition options:
    • Option to instruct SRH-2D to allow 2D flow for overtopping an HY-8 culvert
    • Option to specify boundary condition arcs as data lines and associate these lines with structures. This allows the controlling water levels used for structures such as weirs and culverts to not be right on top of the structure.
  • Option to define pressure zones as a dataset. This allows arbitrary bridge geometry. This is coupled with a tool that will convert 3D bridge objects into a "ceiling" dataset for this purpose,
  • New "Water Surface Elevation Dataset" initial condition option in the SRH-2D Model Control dialog.
  • Option to output spatial datasets of "maximums" and "times of maximum".
  • Updates to SRH-2D material coverage and material properties.
  • Sediment transport parameters are now set on in the SRH-2D Model Control dialog.
  • The Populate dialog has been replaced by the Channel Calculator dialog.
  • Improved management of HY-8 linkage.
  • Functionality to import "Model Native" files (srhhydro, etc.) and create representative simulations.
