The objective of this project was to determine the quality characteristics of stormwater draining from an urban land drainage basin in North Carolina as influenced by the nature of land use on the basin. A number of areas in North Carolina and elsewhere are confronted with the need to require high degrees of water quality management. Urbanization of a region has an effect on the quality of its stormwater. The purpose of this study was to determine quantitative relationships between different land-use patterns and consequent differences in the water quality. The drainage basin selected has an area of 1.67 square miles and is in the upper portion of the Cape River Basin of North Carolina. Residential, commercial and industrial activities on the selected basin are representative of the urban land-use pattern in North Carolina cities and towns. During the first year a gaging and sampling station was installed on the outlet of the major basin. Sampling and analyses were initiated to characterize the quality of water draining from the basin and its two major constituent basins. In the second year, the major basin was divided into a number of subsidiary basins to characterize the quality of water draining from each sub-basin and attempt correlation of its qualities with land use.
