Satellite-Based Estimates of Groundwater Storage Changes at the Najd Aquifers in Omana significant decreasing were observed from 2010 to 2014. The groundwater storage over Najd aquifers was decreased by about 0.44 and 0.46 km./year as calculated from GRACE data and groundwater levels, respectively. We also found that groundwater storage was affected by the strong storm events as obs

Evaluation of Water Erosion Risk in Tunisian Semi Arid Areae layering on rainfall, soils, topography, vegetation cover provides synthetic card distribution rate to erosion in t/ha/year. From results, we can conclude that the hilly lake is characterized by low erosion with siltation rate about 1.8 t/ha/year. The evolution of water and soil conservation works
