In this study, pollutant flushing characterizations of stormwater runoff were analyzed in a rapidly urbanizing area based on field monitoring. The results showed that both imperviousness and rainfall intensity have a positive impact on first flush effect. Significant end flush effect exists in rapidly urbanizing areas and it occurs more frequently than first flush effect under the condition of high proportion of agricultural land use and light rainfall intensity. Compared to urban areas, first
