Abstract: A site specific model for water and sediment yield was developed to estimate water quality aspects of the Tucannon River Basin. In this paper, the relation of water and sediment yield to upstream land use, land management, and soil and water conservation measures are reviewed. Simulation results of water and sediment yield in the Tucannon River are presented and compared to longterm observed values near the outlet of the Tucannon River Basin. These results reflect 1980 land use conditions and represent base line conditions for a proposed alternative analysis. The results compared well and the computer program was found to be an effective tool to estimate water and sediment yield of the Tucannon River.
