Abstract
Because of the need to establish a more reliable source for irrigation, National Irrigation Administration (NIA) Region IV-B MIMAROPA, approved the Bongabong River Irrigation Project (BRIP), which envisions to provide adequate water supply to about 6000 ha of agricultural land both during wet and dry seasons in Bongabong and Roxas, Oriental Mindoro. In order to device a model that would predict runoff or stream flow at which information such as peak flows, low flows, and monthly runoff volume may be achieved, Rainfall Runoff Library was used. Runoff was simulated using five models namely AWBM, Sacramento, SMAR, SimHyd and Tank model that were optimized using a series of optimizers such as Genetic Algorithm, Pattern Search and Rosenbrock Method, respectively. The performances of each model were compared using Nash-Sutcliffe Efficiency (NSE). Peak flows and low flows were assessed and the highest peak flow was compared with the maximum design discharge. Results showed that using Tank method yields the greatest efficiency for calibration equal to 0.902 and AWBM performed best during validation with NSE equal to 0.827. The optimum parameters for the Tank model were used in order to generate the streamflow data for the ungauged period. Results showed that the highest peak flow is still acceptable.
