20090150088 | METHOD OF ANALYZING BEHAVIOR OF POLLUTANTS THROUGH PREDICTION OF TRANSVERSE DISPERSION COEFFICIENT USING BASIC HYDRAULIC DATA IN STREAM - Disclosed herein is a method of analyzing the behavior of pollutants in a stream through the prediction of a transverse dispersion coefficient. The method includes the steps of (a) surveying and storing stream data, including the flow velocity, depth, sinuosity, width and longitudinal dispersion coefficient of a target stream; (b) deriving a transverse dispersion coefficient by arranging only dimensionless factors that influence transverse mixing through dimensional analysis, and assuming that the transverse dispersion coefficient is a product of power functions; (c) collecting hydraulic data and transverse dispersion coefficient data of domestic and foreign streams; (d) deriving the predicted value of the transverse dispersion coefficient from the transverse dispersion coefficient through regression analysis; (e) obtaining a numerical solution by constructing a numerical model using the flow velocity, depth, sinuosity, width and longitudinal dispersion coefficient of the stream and the transverse dispersion coefficient. | 06-11-2009 |
