Effect of rainfall hyetograph on pollutant loads in an urban catchment area

K. Michiokui, N. Wada & Y. Tsuji
Field measurements and runoff analysis of stormwater in a small urban area were performed. The effects of rainfall hyetograph on the pollutant runoff process were examined. Excellent agreement between SWMM simulation and field data were found not only with the runoff discharge, but also with the concentration and washoff rate of nutrients. A response analysis of pollutant runoff was carried out for design storms of single-peaked triangular hyetographs with various durations and peak intensities. The...
