Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Snake River at Weiser, ID – USGS site ID# 13269000. The model can be used to develop a time series of suspended sediment concentration based on acoustic backscatter and tributary flow data to determine the suspended sediment concentration at the site in real-time. The suspended sediment time series will help enable science entities, managers, and others, track the movement of sediment in the Snake River above Brownlee Reservoir.
