Summary

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 [...]

Summary

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 Osage Creek near Cave Springs, AR, a total of 56 suspended-sediment samples were collected beginning on March 20, 2012 and ranged from 1 to 1480 milligrams per liter across a range of turbidity from 0.8 to 911 formazin nephelometric units and streamflow from 26.6 to 5640 cubic feet per second. There were 40 suspended-sediment samples used in the final model after removing samples associated with sampling or fouling errors and extraneous samples from the same storm event which would result in overfitting of the model.

Purpose

Sedimentation is one of the leading causes of stream impairment. However, consistent collection of sediment data is both time consuming and resource intensive. Turbidity is frequently collected where water-quality data is collected and is a useful surrogate for calculating suspended-sediment concentration (SSC). Turbidity can be measured continuously at a relatively low cost via in situ monitors with optical sensors. Instantaneous turbidity data and suspended-sediment samples were collected by the U.S. Geological Survey (USGS) at Osage Creek near Cave Springs, AR (gaging station 07194880) and used to quantify SSC. A time series of SSC at the stream site was produced via linear regression of instantaneous turbidity values and measured suspended-sediment data, providing SSC from unit value (15-minute) turbidity data. This study was conducted by the USGS in cooperation with the City of Rogers and Rogers Water Utility.
