Spatially varied data, or spatial datasets are integral to the use and application of the CMS-Flow numerical engine. The engine uses spatial data for input and each process simulated by the engine creates spatial datasets that can then be visualized and used for post processing in the SMS.

Input Datasets

CMS-Flow has several spatially variable input fields. The inputs are sorted by process and labeled with units below.

Hydrodynamics

Variable Units Symbol Description
Bottom Friction NA (none) Roughness of the bottom used to simulate resistance to flow. For example, this could be based on a Manning value.

Sediment transport/Morphology change

Variable Units Symbol Description
D50 milimeters (mm) Median grain size for particles in each cell of the grid domain
Hard Bottom meters (m) Constraint for maximum erosion for each cell of the grid domain

Salinity

Variable Units Symbol Description
Initial Concentration parts per thousand (ppt) Initial salinity concentration for each cell of the grid domain

Output Datasets

Hydrodynamics

Variable Units Symbol Description
Water Surface Elevation meters (m) Elevation above mean sea-level computed at the centroid of each cell.
Current Velocity meters per second (m/sec) Velocity components in the u and v directions computed at the top and right side of each cell. The SMS interface interpolates these values over the cell, converts them to global world (x, y) values and displays these as vectors.
Flow Rate cubic meters per second (m3/sec) Flux over each cell.

Sediment transport

Variable Units Symbol Description
Concentration Capacity kilogram per meter cubed (kg/m3) Total transport capacity for flow in the cell. Computed for LUND-CIRP, van Rijn, and Watanabe transport equations.
Sediment Concentration kilogram per meter cubed (kg/m3) Computed suspended sediment concentration at the centroid of each cell
Sediment Transport Rate cubic meters per second per meter (m3/sec/m) Computed transport rate across the right and top faces of each cell. Displayed as a vector quantity in SMS

Morphology change

Variable Units Symbol Description
Bed depth meters (m) Depth below mean sea level to current floor of the model (positive values measured downwards)
Change in depth meters (m/sec) Change in the depth at each cell since the start of the simulation

Salinity

Variable Units Symbol Description
Salinity Concentration parts per thousand (ppt) Concentration at each cell centroid
