摘要

On the supposition that the runoff on the catchment of each gully flows into the gully itself, a model of surface storm-water runoff at urban gully was presented and the rainfall event, runoff-generated event and runoffconverged event were characterized by instantaneous rainfall intensity, runoff coefficient of integrative area and the principle of equal time of flowage, respectively. The idiographic form of the model at two gully inlets in Shapingba District of Chongqing was determined. The model was calibrated with the research results, which come from the synchronized measurements of water quantity and quality at the two gully inlets obtained from July to September 2000. The relative error was calculated by comparing the model predictions with the field-measured results.
