Improving quantification of rainfall runoff pollutant loads with consideration of path curb and field ridge

Quantifying the pollutant loads in rainfall runoff plays a critical role in non-point source pollution control at the watershed level. However, the retention effect of path curb in urban areas and field ridge in farmlands on surface rainfall runoff volume and pollutant loads is still unknown and pai...
