| Abstract | A modeling approach with Agricultural Non-point Source Pollution Model (AGNPS) used to
simulate runoff, sediment and nutrient yields from Huai Nong Prong watershed in
Southeastern Thailand. The objective was to verify the applicability of the AGNPS model
(Version 5.00) for the simulation of runoff, sediment and nutrient yields from the selected
watershed. Extensive field and observed data were collected and the model was calibrated
and validated.
Calibration and validation results showed that the AGNPS model could be used successfully.
It revealed that the runoff volume, calculated by the SCS curve number method, and the
nutrient yields are simulated with better accuracy than that of sediment yield. The peak flow
calculated by CREAMS equation is overpredicted by the model and needs modification in
the model component itself.
This study revealed that the cell subdivision in the AGNPS is more sensitive to sediment and
nutrient yields than that of runoff volume and that the peak flow simulated by the model is
not sensitive to the cell subdivision. |
