摘要
为分析第二松花江下游洪水过程对河水-地下水交换的影响,以第二松花江下游德惠河段2016年10月15日~11月16日经历的一次涨洪—退洪过程为例,根据热示踪法,运用VFLUX2.0.0程序计算了该河段河水—地下水交换强度,探讨了洪水前和洪水过程中研究区河水—地下水交换模式及交换强度的变化。结果表明,洪水过程改变了河水—地下水交换模式,使交换强度增加。研究结果为该流域地下水资源的评价与管理、地表水与地下水的综合利用提供理论依据。
Taking a flood process happened at the lower reaches of the Second Songhua River in Dehui channel segment from October 15 to November 16,2016 for an example,in order to analyze the impact of flood process on rivergroundwater exchange at the lower reaches of the Second Songhua River,the VFLUX2.0.0 program was used to calculate the exchange flux between river water and groundwater based on the heat tracing method.The changes of river-groundwater exchange pattern and flux before flood and during the flood process were discussed.The results show that flood process altered the river-groundwater exchange pattern and increased the river-groundwater exchange flux.This study provides theoretical support for groundwater resources evaluation and management as well as comprehensive utilization of surface water and groundwater.
