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 growing need to mitigate rainfall-runoff pollution, especially first flush, calls for accuratequantification of pollution load and the refined understanding of its spatial-temporal variation.The wash-off model has advantages in modeling rainfall-runoff pollution due to the inclusion of two keycharacteristics dominated by land pollution and rainfall pollution, respectively.The enhanced model can provide deeper insights into non-point pollution mitigation.
