Sediment and Nutrients Loadings from the Upper Pearl River Watershed

Author(s): Parajuli, P.

Sediment and nutrients loading from the non-point sources of agricultural and non-agricultural activities contribute to water quality degradation. Developing Total Maximum Daily Loads (TMDLs) for the sediment and nutrients require quantifying pollutant load contribution from each potential source. Quantifying pollutant loads from each source will help in developing pollutants reduction strategies to meet applicable water quality standards. The objective of this research was to monitor sediment and nutrients concentrations and quantify daily, monthly and annual pollutant loadings from the Upper Pearl River watershed (UPRW-7,885 km2) in east-central Mississippi. Analysis of average NCDC rainfall, USGS stream flows, observed sediment, and nutrient data from the watershed will be presented. Preliminary results from the model simulations will also be presented using appropriate statistics.
