This important aspect of the catchment emphasizes to use Global Climate Models (GCM) extensively rather than gauge products for various hydrological investigations. The main goal of this study was to apply the bias correction technique on GCMs and to evaluate them for a hybrid topography and determine how well they may be used for predicting the stream flows. A strong relation was found to be existed between the gauge and the model. The amount of error and the performance of the model was evaluated by using the statistical and performance parameters for point precipitation, average basin rainfall and entire study area. Flow routing was done to predict the stream flows for gauge, ACCESS 1.0 and adjusted ACCESS 1.0 products for the years 2014 to 2019. The upstream boundary condition, to accommodate the flows from upper basin, was provided at Kohala station in the form of monthly hydrograph. The model showed comparatively good results after applying the bias correction factor and the stream flows were close to the gauge data.enBias correction of cmip5-based precipitation for hydrologic investigationsA case study of lower jhelum river basin, pakistan.Thesis
