Sediment calculation
FunctionSlope sediment generationSlope sediment transportationGully sediment generationStream sediment erosionStream sediment transportation
Meaning of parameter and its value range ACM: coefficient of hydraulic erosion capacity on slopes (0.001–1) : scour and deposition coefficient (0.01–1) CGM: average sediment yield concentration in gully (>0) KXD: dynamic nonlinear coefficient of scouring and deposition (0.1–0.999) KXG: average propagation time of sediment particles in river reach (0.2–3) 
CM: maximum sediment concentration of slope streamflow in the whole basin (5–2000) CSS: rill erosion coefficient (0.1–250) XS: proportion coefficient (0.1–0.55) 
REMM: maximum erosion resistance of watershed (>0)
BS: distribution curve index of erosion resistance (0.1–5)
