Fall velocity

For uniform sand you must specify the fall velocity of the material for each point in the bathymetry. The fall velocity can be specified in two ways

·         Constant

·         Varying in domain (for Littoral drift only)

For the case with values varying in domain, you have to prepare a data file containing the fall velocity. The file must be a line series file with the same grid spacing and number of grid points as the cross-shore profile.
