The wadi dahab delta is in a dry, arid coastal zone within Egypt’s south Sinai Peninsula’s eastern portion. The prim.ry water source is the Quaternary coastal alluvial aquif.r. The groundwater salinity varies f.om.890to 8213 m./L, with a m.an value of.3417 m./L. The dissolved m.jor ions have been used to calculate the seawater m.xing index(SWm.) using a linear equation that discrim.nates the groundwater m.stly af.ected by water–rock interaction(SWm. 1>) and other sam.les m.xed with Seawater(SWm. m.osition of.groundwater f.r specif.cally chosen groundwater sam.les ranges f.om.0.645‰ to +5.212‰ f.r δ^(18)O and f.om.9.582‰ to + 22.778‰ f.r δ^(2)H, where the seawater represented by a Red Sea water sam.le(δ^(18)O + 1.64‰-δ^(2)H + 9.80‰) and reject brine water are considerably enriched the isotopic groundwater values.
