Abstract
Stormwater runoff models using the dynamic wave method, diffusion wave method and kinematic wave method were applied to an urbanized lowland basin which was the pump drainage area of the Shinkomatsu River. The simulation was carried out for fourteen rainfall events in 1991. The results confirmed that the simulated hydrographs of the dynamic and diffusion wave method were shown to compare favorably with the observed hydrographs rather than the kinematic wave method. Further, it was found that the diffusion wave method was a proper model for an urbanized lowland basin, because of its shorter analyzing times and simple form of equations, compared with the dynamic wave method.
