ENHANCING RAINFALL-RUNOFF POLLUTION MODELING BY INCORPORATION OF NEGLECTED PHYSICAL PROCESSES

Frontiers of Agricultural Science and Engineering 2023, Volume 10, Issue 4,   Pages 553-565 doi: 10.15302/J-FASE-2023519

Abstract: The wash-off model has advantages in modeling rainfall-runoff pollution due to the inclusion of two keyphysical processes, build-up and wash-off.This study integrated the Soil Conservation Service curve number (SCS-CN) into the wash-off model andThe enhanced wash-off model was validated in a typical rural-residential area.The results showed that the model performed better than the established wash-off model and the commonly-used
