Data and Regression Model for Suspended Sediment for Iroquois River near Foresman, Indiana, March 20, 2015 to July 19, 2018

The primary data set consists of continuous water-quality data (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate plus nitrite, and streamflow) from in-situ equipment, and discrete water-quality samples (total nitrogen, total phosphorus, suspended sediment concentration, and suspended sediment sieve diameter) collected during site visits at the USGS streamgage Iroquois River near Foresman, Indiana, April 7, 2015 to July 19, 2018. These continuous and discrete measurements were used to develop a regression model which may be used to compute concentrations and loads of suspended sediment. The secondary data set consists of daily streamflow and daily turbidity values collected continuously by in-situ monitors at Iroquois River near Foresman, Indiana March 20, 2015 to July 19, 2018 which serve as input explanatory variables for the developed regression model to compute suspended sediment at Iroquois River near Foresman. The tertiary data set for March 20, 2015 to July 19, 2018 is the output data set that was developed by application of the regression model and includes the computed daily mean suspended sediment concentration (concentration, upper 95-percent prediction interval, and lower 95-percent prediction interval) and daily mean suspended sediment load (load, upper 95-percent prediction interval, and lower 95-percent prediction interval) estimates.
