Quantification of urban hydrologic response of catchments to rain fall is one of the most importantissues in urban hydrology. Despite its importance, there is scant information by means of whichrequired data can be obtained for quantifying hydrologic response. In this study, urban database wasdeveloped for a part of Baharestan City in Isfahan Province and using the information, the urbanunit hydrograph was determined through URBS-UH model for two catchments of Baharestan. Peakof hydrograph of the first and second catchment was estimated 0.0727m3/s and 0.096, respectively.Flood hydrograph of some rain occurred previously in Baharestan was determined through the unithydrograph. Peak discharge of flood was also measured and the efficiency of the developed modelwas examined based on the peak information. Nash–Sutcliffe coefficient of the first and the secondcatchment were estimated 0.89 and 0.79, respectively. The developed model showed good to verygood performance in the pilot area.
