Hydrochemical Properties of Shallow Groundwater along the Weihe River in Huaxian County and Huayin City, Shaanxi Province
摘要
Abstract
The Weihe River flows through Huayin City and Huaxian County. According to the analyzed results of shallow groundwater samples collected in Huayin City and Huaxian County, in this paper the spatial hydrochemical properties and their evolution of groundwater are studied systemically. The results show that shallow groundwater in the study area is mainly recharged by groundwater from the Qinling Piedmont, and it in the areas along the river-banks relies mainly on the lateral recharge of the Weihe River. The hydrochemistry type in the areas of groundwater recharge, runoff and discharge changes from HCO3 · SO4 - Ca · Mg to S04 · HCO3 - Na · Ca and then to SO4 · Cl - Na; the salinity and hardness of groundwater increase gradually and reach to their maximum values in the funnel-shaped zone of groundwater; Cl- , Mg + and Na+ are gradually accumulated, and groundwater quality trends to salinization. The study results can provide the references for understanding the effect of the Weihe River on ground-water quality in the areas along the river and for rationally utilizing groundwater resources in the study area.关键词
