Include/exclude effect of bed slope

You must also specify whether you want MIKE 21 ST to account for the effect of bed slope on the bed-load transport rates or not. The influence of the bed slope on the rates of bed-load transport is much more noticeable for a trans­verse slope than for a longitudinal one. This option is only available for the Engelund & Fredsøe and Zyserman & Fredsøe transport theories.
