The main objectives of the Canadian Streambank Erosion Study were to gain a better understanding of bank recession mechanisms and to characterize and quantify the material eroded on a representative number of sites such that actual contributions of sediment to study basins might be calculated. An intermediate goal of the research was to determine if, from their characteristics, the amounts of sediment produced from streambank erosion could be predicted. Evaluation and analyses of on-site erosion in the study watersheds also afforded a picture of the seasonality of streambank erosion and land management practices associated with problem areas. Lastly, it was projected that data obtained on the study watersheds could be extended to give rough estimates of the contribution by streambank erosion in the Canadian portion of the Basin to sediment and nutrient pollution in the Great Lakes. The objectives of the U.S. study were to evaluate the effect of material eroded from riverbanks on water quality of the Great Lakes, to determine measures for riverbank protection and the cost of such a program.
