Spatial and Temporal Changes of Groundwater Storage in the Quaternary Aquifer, UAE

To study the temporal and spatial variations of groundwater quantity quality in response to intensive exploitation from Quaternary aquifer UAE, a water budget model with cell size one km2 was developed. The available historical records levels salinity have been used develop table maps UAE for years 1969, 2005, 2010, 2015. resources soil information system facilitate validity, cogency, consistency analysis. analysis module GIS define setting, saturated thickness, base elevation, effective porosity, at each grid cell. obtained results indicated that volume fresh has decreased 238 km3 1969 around 10 A major part these depleted replaced by brackish water, and, therefore, total storage this only 977 922 2015, respectively. If same continues, freshwater surficial might be totally agricultural areas. Most probably, will exploited. In such areas, more attention should devoted management avoid exacerbation saltwater intrusion problem. Despite fact indicate negative impacts improper small arid area, learned lessons are valid other countries, particular, using proper steady state boundary conditions initial modeling future alternatives.
