Suspended sediment yields were determined for 36 basins and dissolved sediment yields for 21 intermediate-sized stream basins in southern Alberta, Canada. Calculation of long term mean sediment loads was based upon the establishment of sediment rating-curves for gauging stations at the basin outlets and the construction of a sediment duration curve from sediment rating and flow duration curves. Mean yearly suspended sediment export ranged from 12.55 tons/sq. mile to 576.9 tons/sq. mile with 58% of the basins yielding less than 200 tons/sq. mile. Dissolved sediment yeilds ranged from 0.89 to 286.6 tons/sq. mile per year with 50% of the catchments contributing less than 50 tons/sq. mile per year. Relationships between sediment yeilds and geomorphic and hydrologic variables were subjected to regression analysis. Highly significant relationships were established between sediment yeilds, unit mean discharge, mean annual discharge, local relief, elevation and mean land slope.
