Surrogate regression models for computation of time series suspended-sediment concentrations, Chester County, Pennsylvania (2020)

In cooperation with the Chester County Water Resources Authority (CCWRA), USGS collected discrete stream samples for analysis of suspended-sediment concentrations at seven gaging stations where near real-time continuous data on stream discharge, and turbidity have been collected since 2005. Regression models were developed to estimate suspended sediment from turbidity measurements at each gage...
