秦皇岛河流-海岸水动力和水质耦合模拟分析
Coupling simulation and analysis of hydrodynamics and wa-ter quality in Qinhuangdao rivers and coastal waters
摘要
Abstract
By coupling a one-dimensional model of river with a two-dimensional model for coastal waters in Qin-huangdao, a model of hydrodynamics and water quality was established based on the MIKE FLOOD. The charac-teristics of flow currents and distribution of pollutants in Qinhuangdao estuaries and coastal waters were subse-quently analyzed. Numerical results show that 1) the tidal current in coastal water is semidiurnal, and although there is considerable change in the current speeds of the north and south branches of the Shihe River estuary, the water level is basically the same. 2) There is a positive correlation between chemical oxygen demand (COD) concentra-tions and current speeds in Qinhuangdao estuaries. 3) The direction of COD transport in coastal waters corresponds to the direction of the tidal current, and the COD concentration is higher in the ebb period than that in the flood period. The above results provide a scientific basis and technical support for research into the red-tide outbreak mechanism and emergency treatment thereof.关键词
