Bed Load Transport Coefficient B

The coefficient B is a proportionality constant in the expression for the total load transport in Bijker's Transport Method (p. 41), and can therefore be used as a calibration parameter.

You will be asked to specify this parameter (together with the relative sedi­ment density s and the water temperature T) only if Bijker's Transport Method (p. 41) has been selected.

A value of the transport coefficient B has to be assigned to every grid point within the model area. This value can be specified in two different ways:

·         a constant value for all grid points

·         a map with a value for every grid point

A value of B between 1 and 5 is expected by MIKE 21 ST. B = 1 is suggested for simulations outside the surf zone, whereas the use of B = 5 within the surf zone is advised.
