Characterization of the Vulnerability of Urban Streams to Nutrient Pollution under varying Flow Regimes
Nutrient pollution is a primary cause of water quality impairment in streams in the United States and throughout the world. Regulatory approaches under the Clean Water Act, such as water quality standards and the Total Maximum Daily Load program, aim to improve water quality. In this study, novel probabilistic methods are developed to characterize vulnerability to nutrient pollution along urban streams and to assess risk of water quality impairment under varying hydrologic conditions. Vulnerability is defined as the probability that ambient conditions exceed desired water quality standards. Both ...
