摘　　要：河流和含水层是水文循环中相互依赖的组成部分,两者间的相互作用会加剧污染物的传播与运移,目前缺乏适当的模型来模拟河流与含水层间的相互作用,无法获得污染物的运移情况。针对以上问题,基于独立河流和地下水流动与运移模型的完全耦合理论,提出了一种基于河流与地下水空间耦合分布的河流走廊污染物运移模型,根据实例解决方案验证了该模型的准确性。结果表明,与现有单一系统模型提供的结果相比,该模型能够更准确地模拟相连河流与含水层的相互作用及污染路径,有利于调查现有污染的影响,并可在考虑地表水和地下水相互作用的条件下为提出相应的管理策略提供依据。Rivers and aquifers are interdependent components in the hydrological cycle.The interaction between them will aggravate the transmission and transport of pollutants.At present,people lack appropriate models to simulate the interaction between rivers and aquifers,and cannot obtain the transport of pollutants.To solve the above problems,this paper proposes a pollutant transport model in river corridor based on the spatial coupling distribution of river and groundwater.The model is completely coupled from the modified version of the most advanced independent River and groundwater flow and transport model.The model is verified according to the analysis solution.The results show that,compared with the results provided by the existing single system model,it can more accurately simulate the interaction and pollution path between connected rivers and aquifers,is conducive to investigating the impact of existing pollution,and can provide a basis for putting forward corresponding management strategies under the condition of considering the interaction between surface water and groundwater.
