A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through use of the Meyer-Peter, Mueller relation. The velocity of the bed load is estimated from a theoretically developed and empirically calibrated equation. Continuity is applied to determine the thickness of the moving bed layer, and the local sediment concentration is derived assuming a logarithmic velocity profile for the water flowing within the bed layer. An updated Einstein procedure is then applied for integration of the suspended load.
