Abstract: Erosion within a watershed can cause extensive damage to the land and adjacent properties. It is a common problem throughout the United States, and has become severe in many areas of the country. Management of in-stream sediment and removal of sediment from reservoirs costs millions of dollars each year, and the loss of agricultural land increases the annual cost. A continuing need exists for development of computational tools to evaluate sedimentation problems effectively so that their impacts can be estimated. This paper explains the development of a sediment transport computer model, data collection, calibration, and effects of the resulting water and sediment discharges as applied to the North Fork Feather River (NFFR) watershed.
