GRACE, GLDAS and measured groundwater data products show water storage loss in Western Jilin, China.
Water storage depletion is a worsening hydrological problem that limits agricultural production in especially arid/semi-arid regions across the globe. Quantifying water storage dynamics is critical for developing water resources management strategies that are sustainable and protective of the environment. This study uses GRACE (Gravity Recovery and Climate Experiment), GLDAS (Global Land Data A...
متن کاملGlobal-scale modeling of groundwater recharge
Long-term average groundwater recharge, which is equivalent to renewable groundwater resources, is the major limiting factor for the sustainable use of groundwater. Compared to surface water resources, groundwater resources are more protected from pollution, and their use is less restricted by seasonal and inter-annual flow variations. To support water management in a globalized world, it is ne...

متن کاملRegional-scale stable isotopic signatures of recharge and deep groundwater in the arsenic affected areas of West Bengal, India
r a 200 .004 esent ad Geoscien ox X, A +1 512 4 kherjee@ Summary Samples of deep groundwater, river water and rainwater were collected for dO and dH analyses from an area of 22,000 km in the arsenic-affected districts of West Bengal, India, in order to examine groundwater recharge. A plot of dO versus dH of groundwater falls subparallel to the constructed local meteoric water line (dH = 7.2 dO ...
