The dramatic increase in space-borne sensors over the past two decades is presenting unique opportunities for new and enhanced applications in various scientific disciplines. Using these data sets, hydrogeologists can now address and understand the partitioning of water systems on regional and global scales, yet such applications present mounting challenges(More)

To address a nation’s or a region’s water-related sustainability problems, one of key elements is to characterize and quantify renewable water resources for a better management. In the arid and semiarid areas, it has been a great challenge to quantify the renewable water resources due to limited access and monitoring systems on the land. This study(More)

Radium isotopes (226Ra and 228Ra) were analyzed in 18 groundwater samples from the Nubian Sandstone Aquifer System (NSAS) and the shallow alluvial aquifers overlying the basement complex of the Sinai Peninsula, Egypt. Groundwater samples from deep Nubian aquifer wells (total depths 747 to 1250m) have 226Ra and 228Ra activities ranging from 0.168 to 0.802(More)
Recharge of the alluvial aquifers flooring Wadi El-Arish in central and northern Sinai, Egypt was investigated. A hydrological model that combined the spatial and temporal distribution of rainfall, suitable infiltration parameters, and appropriate sub-basin unit hydrographs to estimate rainfall excess, transmission losses along stream networks, and(More)
