摘要
Natural and anthropogenic stresses such as climate change,drought and deluge,increasing water use,land use and agricultural practices affect surface and groundwater resources globally.A small change in the hydrological cycle may have a significant socio-economic impact,which,for example,has recently been observed in the form of groundwater depletion in northwest India probably leading to reduction of agricultural output and shortages of potable water.It is thus of importance to determine the spatial and temporal variability in continental water storage.
