dc.description.abstract Groundwater is the world largest freshwater accessible stock. It is available in aquifers distributed widely in Sudan. Gash aquifer is annually recharged by Gash River. It is the only source for perennial agriculture and domestic uses. This study aims to identify the risks associated with current uses of Gash aquifer. The geographical location of the study area was identified as well as the flow characteristics of Gash river. The irrigation development and phases of progress that took place in Kassala horticultural area during previous decades was also considered. Groundwater uses for both irrigation and domestic purposes were quantified. Analysis and evaluation are basically focused on the current situation of groundwater use; mainly the annual recharge of Gash River and pumping rates. During 2009 season, the annual recharge depth was 2.74 m representing the mean water table rise, through observation wells, that occurred during the recharge period (June-October). This rise is equivalent to 46 million m3 based on aquifer characteristics of Kassala section. The study also outlined the relationship between recharge and river discharge and verified that this recharge corresponds to the lowest river discharge of 452.75 million m3. Annual pumping rates for both irrigation water and domestic use were found to be 104.77 (106) m3 and 11.81 (106) m3, respectively, taking in consideration the seasonality. The budgeting verified that in 2009 pumping rates were 2.5 times greater than the annual recharge, yielding an annual over use of 70 (106) m3, lowering water table by 1.2 m. The study recommended the adoption of efficient irrigation system such as sprinkler and using of artificial recharge wells. en_US
