The Soil and Water Assessment Tool SWAT model was applied to the Canale d Aiedda Puglia, Italy , a Mediterranean temporary karst river basin. Different basin delineations and model parameterizations were adopted that include i cutoff of the karst areas configuration A ; ii basin set up including the karst areas configuration B and iii model parameterization considering a bypass flow in karst sub basins configuration C . The model performance was satisfactory for daily streamflow for configurations B and C and good for A. A better simulated large floods. C presented the best fit for monthly streamflow from May to July. Regarding the water balance, C showed higher values of surface runoff and lower values of total water yield than A and B. Bypass flow proved to be a valid option to improve the simulation of the hydrological processes in karst areas.
