Abstract

The object of this study is to locate the zones of groundwater discharge into the eastern shores of the Dead Sea. To achieve this object the electrical conductivity-temperature with a depth method was used. This study show ed that the Dead Sea divides into two layers relating to the electrical conductivity and temperature with depth. The upper layer subdivided into two members. The upper member extends from the sea surface down to a depth of 15-25 m. The lower member extends from a depth of 15-25 m to 40 m and it characterized with high TDS and low EC. The second layer extends from a depth of 40 m to the end of profiles. Laboratory expe riments carried out to find a relationship between the EC at a specific T and the TDS. These experiments indicate that the EC reaches its maximal 202 mS/cm at a salinity of about 267 g/l from where it starts decreasing with the increase of the TDS and it reaches about 175 mS/cm at a salinity of 404 g/l. The minimal of TDS was observed at about 460 g/l at EC about 156 mS/cm. The submarine groundwater discharged into the Dead Sea in the upper 16 m in Sweimah area. It is discharged in the upper 25 m in Zarka Ma’in area, in the upper 15 m in Zara.
