How to set the value of surface erosion rate in sediment.in?

[leon]

Dear all,
I am using the sediment model now. However, I'm confused about the value of surface erosion rate in the sediment.in file. Actually, a lot of factors influence the surface erosion rate, such as sediment diameter, current speed and so on. Other values can be caculated using the Sediment Particle Property Calculations (http://woodshole.er.usgs.gov/staffpages ... Calcs.html). However, the calculation is only about the non-cohensive sediment. What about the cohensive sediment? ANd how can I caculate or estimate the surface erosion rate? And the bed load transport rate coefficent? Any references?
Thank you very much~
