Abstract: The urbanization is a recent enough phenomenon so much in the industrialized countries that in the developing countries. One of the most visible consequences of the urbanization is the impermeabilisation of soils, which influences considerably on the features of the hydrological response of the watershed and was often bets forward to explain the urban flooding by runoff. In this study, we used like model of simulation, the non-distributed one of linear reservoir, to determine the influence of the urbanization on hydrological response of the watershed. The obtained results show that in case of the urbanization, the lag time of the considered watershed is a lot shorter and also the peak flow increases considerably.
