The hydrodynamic circulation model CMS-Flow is a component of the Coastal Modeling System developed by the US Army Corps of Engineers Coastal and Hydraulics Laboratory. CMS-Flow is a two-dimensional, finite-difference numerical approximation of the depth-integrated continuity and momentum equations. Cells are defined on a staggered, rectilinear grid and can have constant or variable side lengths. The momentum equations are solved in a time-stepping manner first, followed by solution of the continuity equation, in which the updated velocities calculated by the momentum equations are applied. The model simulates currents, water level, sediment transport, and morphology in the coastal zone. CMS-Flow was designed to model navigation channel performance and sediment exchanges between the inlet and adjacent beaches in the coastal zone.
CMS-Flow Model Features and Highlights:
Robust flooding and drying
Efficient grid storage in memory
Time-varying wind and wave stress forcing
Time-varying water level, tidal, and flow-rate forcing
Variably-spaced bottom friction
Independently turn on or off advective terms, mixing terms, salinity, sediment transport, morphology, and flooding/drying calculations
