Stormwater hydrographs from the typical urban impervious subcatchments are analyzed theoretically using the nonlinear reservoir method and the sector method. The peak flow rates of hydrographs from the impervious rectangular subcatchments are 0.774 times less using the nonlinear reservoir method comparing the sector method for all investigated input parameters.
