Description :
This paper describes modifications made to the MMF model to allow the effects of vegetation and crop cover on erosion to be expressed through measurable properties of plant architecture instead of empirically derived coefficients. Tests with this modified model using field measurements under a range of slope, soil and crop covers from Bedfordshire and Cambridgeshire, UK, give good predictions of mean annual soil loss.
