Model Archive Data for Suspended-Sediment Regression at Station 07355860, Board Camp Creek near Wolf Pen Gap Recreation Area near Nunley, AR

Metadata Updated: July 6, 2024

Data from an optical turbidity sensor deployed at the stream station were recorded at 15-minute intervals by a data logger and uploaded every hour to the U.S. Geological Survey (USGS) database (Anderson, 2005; Wagner, 2006). Suspended-sediment samples were collected using a suction pump autosampler, equal width increments, or grab sampling techniques (Edwards, 1999). The use of an optical sensor to continuously monitor turbidity provided an accurate estimate of sediment fluctuations without the collection and analysis costs associated with intensive sampling (Office of Surface Water Memorandum 2016.07; Rasmussen et al., 2009). Turbidity was used as a surrogate for suspended-sediment concentration (SSC), which is a measure of sedimentation and siltation. Regression models were developed between SSC and turbidity using turbidity data from the optical sensor and the SSC data collected from the suspended-sediment samples. For Board Camp creek near Nunley, AR, instantaneous turbidity measurements began on May 01, 2018, and ranged from 0.1 to 2760 Formazin Nephelometric Units (FNU). A total of 62 suspended-sediment samples were collected and ranged from 1 to 1800 milligrams per liter (mg/L) across a range of streamflow from 1.25 to 2060 cubic feet per second (cfs). There were 37 suspended-sediment samples used in the final model after removing quality assurance/quality control samples, samples corresponding with gaps in turbidity data, samples associated with sampling/fouling errors, and extraneous samples from the same storm event which would result in overfitting of the model.
