The diffuse pollution of phosphorus is one of the problems of the eutrophocation at reservoirs and costal area. The purpose of this study is measurements of concentrations of dissolved phosphorus (DP) and particulated phosphorus (SS-P) in urban river and the examination of the runoff processes of DP and SS-P. AS a result of investigations, the peak concentration of DP occurred before the peak of discharge and that of SS-P occurred at that of discharge at the flood event. The source of SS-P at the flood event might be the sedimentation on the streambed.
