Degradation is represented by lumped 1st-order kinetics. Distinct biological and chemical transformation processes are not included. Degradation products are currently not simulated. Suspended sediment is held constant in a link or is a function of discharge as specified in a user supplied rating curve. Unsteady flow hydrodynamics are not represented.
Erroneous results can occur if stability criteria are violated.
Limited - will be increased in future versions. Free if under an undefined deadline. Otherwise, under corporate fee structure. Sediment properties include initial suspended sediment concentration, settling velocity, resuspension velocity, porosity of bed sediment, and bulk density of bed sediment. A time history of unit drainage area discharges are also required.
