Hydrogeological conditions and groundwater level dynamics characteristics of Hi-tech Industrial Development Zone in Tongnan
摘要
Abstract
In order to explore the dynamic changes of groundwater level in Tongnan High-tech Industrial Devel-opment Zone from the dry season to wet season,the authors in this paper combined traditional hydrogeological sur-vey methods to analyze the groundwater types and distribution and obtain the hydrogeological parameters,based on 35 water geological drilling data and 5 existing monitoring well data.Three hydrogeological units were divided ac-cording to the interpolation analysis of the static groundwater level data,and the groundwater level variation char-acteristics of hydrogeological boreholes and monitoring wells within each unit were analyzed.The results are as fol-lows.① Shallow groundwater level responds quickly to precipitation infiltration recharge,with an increase in wa-ter level amplitude,but there is also a time lag.Partial areas receive rainfall replenishment for approximately 2 days.② Daxigou,Lusi Creek and Fujiang River are the erosion base level for the three hydrogeological units re-spectively.For boreholes near the erosion base level,the variation of groundwater level is slightly affected by rain-fall.③ The elevation of the borehole in Zone Ⅰ is almost positively correlated with the groundwater level inside the borehole,while boreholes with soil layer thickness exceeding 5.0 m in Zone Ⅲ have the same correlation.④ For boreholes with soil layer thickness greater than 5.0 m in Zone Ⅱ and Ⅲ,and greater than 10.0 m in Zone Ⅰ,the variation of groundwater level shall not exceed 0.40 m.The research results have guiding significance for the as-sessment of groundwater environmental impact in Tongnan Hi-tech Industrial Development Zone.关键词
