Abstract.
This study investigates the seasonal changes of nutrients, BOD, temperature, and the dissolved oxygen (DO) concentration fluctuation in North Buffalo Creek in Greensboro North Carolina. The stream is a part of Haw River watershed in the Piedmont Triad area of NC. During low flow seasons, the flow in the creek is maintained by the North Buffalo Creek wastewater treatment plant effluent that almost doubles the water quantity in the creek.
The long-term time series data of water quality parameters were analyzed for its correlation using statistical methods and further investigated for “what-if” analysis using modeling approach. The seasonal changes in water quality parameters for the period of 2009 to 2016 were investigated by conducting a statistical analysis using MINITAB software. Generally, the correlation results showed a low statistical connection between the tested parameters and the DO content in the stream.
An instream water quality model was developed for the North Buffalo Creek using Water Quality Analysis Simulation Program (WASP) model. The model setup was calibrated and validated for steam flow and water quality variables. The well-calibrated model was then used to test various scenarios to understand the effect of nutrients loading on the creek’s water quality especially DO concentrations.
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) software package, developed and facilitated by the Environmental Protection Agency (USEPA) was used to build a stream network and segmentation.
Data handling and visualization were carried out using Water Resources Data Base (WRDB 6.1) program, which was used in conjunction with WASP model to view and analyze the model results.
The modeling application has potential to be used for total maximum daily loads (TMDL) studies, by predicting the water quality response to the loading changes. This study tested two scenarios of increasing daily loading to examine the DO response downstream of the creek. DO concentration was found to be sensitive and decreasing significantly as a result of increasing loadings.
