英文摘要	Groundwater recharge is one of the most important terms of water budget, and its assessment is crucial for groundwater management and protection. Several methods have been tested for different climatic and hydrogeological conditions for both diffuse and focused recharge. The present paper proposes to combine a geochemical technique and a numerical modelling method to estimate diffuse recharge rates in an arid region using climatic and soil dataset. Located in an arid region in Central Tunisia, the Kasserine Aquifer System (KAS) is a transboundary aquifer extending into the northeast of Algeria. The main regional reservoir of the KAS is the deep Miocene sandstone representing the main available source of water supply in the area. This research aims to estimate recharge in an arid context. Chloride mass balance (CMB) in both unsaturated zone and groundwater and numerical modelling are the retained methods to fulfil these objectives. The variably saturated model HYDRUS-1D was calibrated using field and climate data at a daily scale for a long period. CMB and model calculations showed that recent recharge rates were between 0.6 and 20 mmyr(-1), representing a groundwater recharge percentage between 0.2 and 6.7% of the rainfall. This work evaluates the groundwater recharge using geochemical and numerical methods which knowledge is pivotal for future investigations on groundwater resources management plans for the KAS.
