Abstract
This paper is part of the special publication No.162, Uplift, erosion and stability : perspectives on long-term landscape development. (eds: B.J. Smith, W.B. Whalley and P.A. Warke). Sediment transport data from 189 gauging stations on rivers in eastern USA and eastern Canada were used to estimate sediment yields. The length of record ranged from one to 42 years. Most stations had marked fluctuations in tonnage from one year to the next. Yields ranged spatially from 1.5t km-2 a-1 to 3157 t km-2 a-1 when the full length of record was used. Multiquadric surfaces were generated to show time-averaged yields using five-year, ten-year, and total intervals of record. The patterns of suspended sediment yield changed when different lengths of record were used, suggesting caution when generating results from a limited record of suspended sediment data.
