Study on the Mathematical Model of Water Pollution and Solution Method by the Highway Transportation with the Poison to Leak Causes

YAN Xin-rong;College of Science,Engineering University of CAPF;  
Transporting of toxic traffic accidents cause the toxic leaks cause water pollution will be a serious impact.This paper first analyzes the characteristics and hazards of pollution incidents.Then according to the law of hydraulics and pollutant transport and transformation,the establishment of a toxic leak water transfer dispersion model,about to control the flow of the St.Venant equations and description poison migration of convection dispersion equation coupled.Low numerical dissipation semi-discrete central upwind scheme for solving equations,its results can predict the length and duration of the polluted river.Finally has carried on the simulation through an example
