ABSTRACT:

The AGNPS model was tested on a small Quebec watershed to evaluate the model's applicability and performance with respect to hydrologic conditions in this province. Sediment yield was simulated for 12 rainfall-runoff events. SCS curve numbers and USLE factors were adjusted to produce better simulations. The antecedent precipitation index was used as a soil moisture indicator. AGNPS storm types and channel scouring parameters were adjusted for the relatively large events. An average error of 28.2%, and a coefficient of performance of 0.01 was observed for predicted values.
