The calculation requires the sediment characteristics for the given location (point/profile).
The grain size is regarded as a representative grain size for a specific grid point in the modelling area. This means that the sediment properties can vary spatially across a profile. On coasts with wave impact, coarser sediment is often found on the beach and on shallow water while finer sediment are found in deeper waters.
