Abstract:
A method for analyzing the behavior of pollutant through the calculation of a transverse diffusion coefficient utilizing the basic hydraulic information of a river is provided to be applied to various geographical conditions and hydraulic conditions by utilizing the universal transverse diffusion coefficient formula with only the basic hydraulic amount of the river. River information is examined and stored. A transverse diffusion coefficient is induced by arranging only dimensionless factors which influences the transverse mixing in a natural river. The hydraulic amount and transverse diffusion coefficient data of domestic/international rivers. Through the regression analysis, a mathematical formula is derived from the transverse diffusion coefficient. An estimate value of the transverse diffusion coefficient is obtained. The numerical model is constructed.
