Datum Definition
The particle module compute grid dataset bin elevations dialog is accessed through the Compute grid datasets dialog. The bin elevations are specified according to the datum selected in the Compute grid datasets dialog.
Fixed Datum
When using a fixed datum, the bins have a constant z-elevation. Be careful if the model uses a depth dataset. For example, if the water surface is at a constant value of 0.0 meters and the depth is a constant value of 10.0 meters, the bins should range from 0.0 to -10.0 meters.
Bathymetry as Datum
When using the bathymetry as a datum, the bins are offsets from the specified bathymetry dataset. This is useful when determining the effects of concentrations on bottom dwelling species, oyster beds, etc. Offsets should always be positive values.
Water Surface Elevation as Datum
When using the bathymetry as a datum, the bins are offsets from the specified bathymetry dataset. This is useful when determining the effects of concentrations on fish migrating at a specified depth, etc. Offsets should always be positive values.
