N2  - The study area is located between latitudes 13o 58{u2019} 21.56{u2019}{u2019} {u2013} 14o 51{u2019} 14.59{u2019}{u2019} N,  and longitudes 32o 47{u2019} 35.65{u2019}{u2019} {u2013} 33o 40{u2019} 4.44{u2019}{u2019} E. Due to its location in the largest agricultural projects of Gezira and El Manaqil areas of Central Sudan, the groundwater regime was investigated using modern GIS tools. The impact of land  use/land cover on groundwater quality was studied using supervised classification  techniques of multi-dates (multi-temporal) satellite images. In addition, the relation  between the surface water resources of the Blue and White Niles and the Nubian  aquifer was carried on. The major ions, nitrate, ammonium, heavy metals and stable  isotopes (e2H and e18O) were measured to achieve these goals. The results of  hydrochemical data were mapped using ArcGIS 10.3©, aquachem and excel  softwares. The results indicated that there are no any evidence for the groundwater pollution resulted from the anthropogenic activities in the study area. Although the  agricultural projects were started with full capacity, since 1960, the pollution traces were absent. The stable isotopes of the 2H and 18O confirmed that the groundwater  of the Nubian aquifer in the study area is recharged indirectly from the Blue Nile  through the Gezira aquifer near the river. Moreover, away from this river, the  influence of recharge is negligible, but the water of the Nubian aquifer still mixed  with water of heavy isotopic composition (recent water), which indicate a specific  recent recharge for the aquifer system
