Computing time-series suspended-sediment concentrations and loads from in-stream turbidity-sensor and streamflow data
Patrick P. Rasmussen, John R. Gray, G. Doug Glysson, Andrew C. Ziegler
2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010: Hydrology and Sedimentation for a Changing Future: Existing and Emerging Issues: Las Vegas, NV, June 27-July 1, 2010
Over the last decade, use of a method for computing suspended-sediment concentration and loads using turbidity sensors—primarily nephelometry, but also optical backscatter—has proliferated. Because an in- itu turbidity sensor is capa le of measuring turbidity instantaneously, a turbidity time series can be recorded and related directly to time-varying suspended-sediment concentrations....
