Bed load transport coefficient B

The bed load transport coefficient, B, is a proportionality factor in Bijker's total-load transport method. Therefore, it may be used as a calibration param­eter when calculating sediment transport rates.

You may specify the bed load transport coefficient as constant or spatially varying. If the coefficient is chosen as constant over the model area, you have to specify only one value for B. If you choose to specify a spatially vary­ing coefficient, a data file containing one item (B) must be specified. You may do this by typing the path and name of the data file (a .dt2 file in the old format and a .dfs2 file in the new format) or by clicking the mouse on the button to the right of the Data File entry. The grid spacing(s) and extent of the data file must be the same as in the HD data file.
