Developement of watershed and reference loads for a TMDL in Charleston Harbor System, SC.

Informally Refereed

Abstract

It is essential to determine point and non-point source loads and their distribution for development of a dissolved oxygen (DO) Total Maximum Daily Load (TMDL). A series of models were developed to assess sources of oxygen-demand loadings in Charleston Harbor, South Carolina. These oxygen-demand loadings included nutrients and BOD. Stream flow and nutrient concentration data fi-om watersheds draining to the Charleston Harbor System were used to establish land use specific watershed loadings to assess existing watershed conditions. Nutrient and DO data collected from 15 stations were grouped into two categories: dry weather and wet weather. Then, he data were evaluated with respect to different types of land use. It was found that nutrient concentrations and DO correlated with percentage of urban land use and percentage of forest reasonable well.
