Effect of tidal flow-runoff coupling on the diffusion of pollutants(COD)discharging by Yellow River
A numerical model of Chemical oxygen demand(COD)transport and diffusion in the Yellow River Estuary is established to study the effect of tidal flow-runoff coupling on the transport and diffusion of pollutants discharging by Yellow River.It is found that with the increasing of discharge,the reducing velocity of COD decreases along the way,and the reducing velocity of true north is the largest.The influence range of runoff on COD diffusion is also given.This paper can be used as a reference for the study of pollutant diffusion in Yellow River Estuary and environmental protection in the surrounding waters.
