This Model Archive Summary (MAS) describes the development of a turbidity derived suspended-sediment concentration (SSC) time-series computation model. The MAS includes all the methods and techniques used to develop the model for USGS stations 11447903 Georgiana Slough Near Sacramento River, Ca. The time-series suspended-sediment concentration data are representative of the cross section and are adequate to compute suspended-sediment flux, to help managers and others to track the movement of sediment in the Sacramento-San-Joaquin Delta and to better understand habitat dynamics.
