Abstract

A preliminary investigation of the applicability of the CREAMS non-point source pollution model to British conditions was carried out by testing the erosion sub-model using field data from mid-Bedfordshire, England. With a sample of 31 storms a correlation coefficient of r=0.87 was obtained between predicted and observed values. This result is better than has been achieved using other models to predict erosion in mid-Bedfordshire and compares well with the results obtained by users of the model in the U.S.A. Three strategies are discussed and the results of the best one presented for operating the sub-model on a hillside where the overland flow and rill flow paths are approximately parallel. The results imply that the channel flow component may need to be redefined to include as channels convergent flow paths within the overland flow.
