Abstract

The rainfall-runoff analysis is extremely imperative in planning and developing water resources. In the present study, Rainfall-Runoff models based on artificial neural networks were developed for the Khanpur dam watershed Pakistan. The meteorological data used for this model was collected by the Water and Power Development Authority (WAPDA). Seven different types of rainfall-runoff models were designed using a daily meteorological parameter (Rainfall, Evaporation, Temperatures, and discharges). For each case, data sets were trained using fifteen neurons and two no of delays, and the data sets were distributed as (80, 10, 10) percent for training, testing, and validation respectively. These parameters were set using trial and error procedures. The above-constructed models were trained using the ANN lavenberg Marquard (trainlm) function. ANN models were validated using cross validation approach for generalization and best model is calibrated using actual data. All models performed well, the NS and R range between (62%-70%) and (0.69-0.82) respectively. the performance of the all models is in satisfactory to good.
