Constituent Load Estimation In The Lower Ouachita-Smackover Watershed, Zach P. Simpson, Erin E. Scott, Brian E. Haggard
Technical Reports
Water quality was monitored at 21 sites in the Lower Ouachita‐Smackover Watershed from 2013 November through 2014 September. The U.S. Geological Survey maintains discharge monitoring stations at two of these sites, Moro Creek (USGS 07362500) and Smackover Creek (USGS 07362100), which were sampled during base flow and storm event conditions, whereas the other sites were only sampled during baseflow. The Arkansas Water Resources Center (AWRC) estimated constituent loads for nitrate‐N (NO₃‐–N), total nitrogen (TN), soluble reactive phosphorus (SRP), total phosphorus (TP) and total suspended solids (TSS) using the U.S. Geological Survey LOADEST software. LOADEST creates regression models between constituent concentrations …
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Sediment At The Arkansas Highway 45 Bridge On The White River Just Above Beaver Lake, Marc Nelson, Wade Cash, Keith Trost, Jennifer Purtle, J.V. Brahana
Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Sediment At The Arkansas Highway 45 Bridge On The White River Just Above Beaver Lake, Marc Nelson, Wade Cash, Keith Trost, Jennifer Purtle, J.V. Brahana
Technical Reports
Automatic water sampler and a U. S. Geological Survey gauging station were established in 1995 on the main stem of the Illinois River at the Arkansas Highway 59 Bridge. Since that time, continuous stage and discharge measurements and water quality sampling have been used to determine pollutant concentrations and loads in the Arkansas portion of the Illinois River. This report represents the results from the measurement and sampling by the Arkansas Water Resources Center -Water Quality Lab for January 1, 2005 to December 31, 2005.
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus In The Bayou Bartholomew At Garrett Bridge, Ar And Near Portland, Ar, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus In The Bayou Bartholomew At Garrett Bridge, Ar And Near Portland, Ar, Marc A. Nelson, L. Wade Cash, G. Keith Trost, Jennifer Purtle
Technical Reports
Water quality sampling stations were installed at the Bayou Bartholomew at Garrett Bridge, AR and near Portland, AR. These stations are coordinated with USGS gauging stations at the same locations. These stations are instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus in the River. Bayou Bartholomew watershed is about 1.08 million acres and is located in the south east corner of the state. The land use in the watershed is mostly in forest and cropland agriculture with some urban area. High turbidity levels and excessive silt …
