摘要
岩溶含水层非饱和带在地下水补给过程中起着重要作用。全面了解岩溶地下水结构和水动力功能是更好地评价和管理岩溶地下水资源的关键。在这篇扩展摘要中，我们介绍了在法国南部Fontaine de Vaucluse喀斯特水系内的低噪声地下实验室(LSBB)进行的为期2年的表面核磁共振(SNMR)监测结果。这项为期2年的特殊SNMR监测首先证明了SNMR在评估和验证岩溶水文系统UZ中地下水的永久存在以及监测其时间变化方面的效率。与钻孔相比，SNMR在不干扰介质的情况下提供了对地下水动态的综合而准确的估计。
Groundwater Dynamics in Karst Hydrosystem Unsaturated Zone; Evidences from a 2-years SNMR Monitoring
Summary The unsaturated zone (UZ) of karst aquifers plays an important role in groundwater recharge processes. Comprehensive knowledge of UZ structure and hydrodynamic functioning is a key to better assess and manage groundwater resources in karst. In this extended abstract we present the results from a 2-year long Surface Nuclear Magnetic Resonance (SNMR) monitoring implemented in the Low-Noise Underground Laboratory (LSBB) site located within the Fontaine de Vaucluse karst hydrosystem in south-France. This exceptional 2-years SNMR monitoring demonstrated the efficiency of SNMR firstly to assess and validate the permanent presence of groundwater within karst hydrosystem UZ and secondly to monitor his temporal variations. Compared to boreholes, SNMR provides an integrated but accurate estimation of groundwater dynamics without disturbing the media.
