摘要: A combined critical source area and flow accumulation model is described that predicts the spatial distribution in risk of diffuse nutrient losses from agricultural fields reaching surface waters. The applied to a number under range different land management scenarios. output highlights importance features such as tramlines, tracks field drains concentrating towards receiving waters increasing delivery pollutants derived sources watercourses. allows scenario analysis likely impact path mitigation on loads.
