WM-99-16 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering Thesis (M.Eng.) - Asian Institute of Technology, 2000 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.
