In order to take measure to reduce flood damages resulting from urbanization, a large number of detention basins have been constructed in many urban catchments.
In the present paper, a simplified method to calculate the runoff from a urbanized river basin with many detention basins using a linear reservoir model is proposed, and the hydrodynamic effect of detention basins can be expressed by an equivalent roughness.
