Three urban runoff models (the Road Research Laboratory hydrograph method, the Storm Water Management Model, and the Cincinnati Urban Runoff Model) were applied to two urban catchments in Australia. The Road Research Laboratory method generally performed well if runoff from previous areas was insignificant. The Storm Water Management Model was best of the three models but also required the most computer processor time. The Cincinnati Urban Runoff Model contained several deficiencies which caused poor performance. Degree of catchment subdivision was found to be an important factor in the magnitude of the peak predicted.
