Methods for Calculation of Water Environment Capacity of Small and Medium River Channels
Abstract:
Methods for calculation of water environment capacity can be divided into two types in general, one type is ideal water environment capacity method and the other is pollution source generalization method. This paper proposes another way of generalization, uniform generalization method, assuming that distribution of the amount of pollutants discharged is uniform in the lengthways direction. In consideration of the practical demand for administration of water resources protection, a formula for calculation of water environment capacity for different combinations of environment function regions is presented,based on the water quality targets of function regions, with the numerical or analytical methods of 1-D water quality model. The proposed method provides a simple and effective method for water resources management and planning.
