SMS - Surface-Water Modeling System V 8.0

SMS Quick Tour (continued)

FHWA Model

SMS includes interfaces to models supported and used by the United States Department of Transportation Federal Highway Administration.

The FHWA models with interfaces in SMS include:

FESWMS - FESWMS is a finite-element hydrodynamic modeling code that supports both super and subcritical flow analysis including area wetting and drying. The FESWMS model allows users to include weirs, culverts, drop inlets, and bridge piers in a standard 2D finite-element model.
BriStars - BriStars is a one-dimensional model designed to predict water surface elevation, velocities and sediment transport.

Generic Model

Any two-dimensional finite-element model can be run using SMS as the preprocessor and postprocessor through the Generic Model. Model parameters are set up including model control and boundary conditions. SMS then saves generic geometry and boundary condition files which can be used in the desired model.

Coordinate Conversions

SMS has coordinate conversions that allow for converting any data contained in SMS to/from several coordinate systems including:

Horizontal Coordinates

Geographic
UTM
State Plane
User Defined System

Vertical Coordinates

NGVD 29
NAVD 88

Scattered Data

SMS supports a powerful array of options for interpolation in the Scatter Point module. The following interpolation options are supported:

Linear
IDW
- Constant, gradient-plane, and quadratic nodal functions
- Multiple search/subset schemes
Natural Neighbor
- Constant, gradient-plane, and quadratic nodal functions

Filtering

Filtering reduces dense scattered data by removing redundant points in planar regions.

Calibration

Model calibration involves changing input parameters until the model results match field observations. SMS provides a suite of options for model calibration including calibration targets and plots of calibration statistics.
