| Soils in arid or semi-arid areas often have salinity problems, so the quality of irrigation water plays an important role in agricultural production. Groundwater quality analysis includes the determination of chloride ions, which are toxic to plants in high concentrations. A total of 1358 groundwater samples were collected and analyzed in the period 1980-2008. Water electrical conductivity [EC] and chloride ion concentration values were related by the linear equation [Cl-] = 4.928 EC (R> 0.94), to estimate the concentration of chloride ions as a function of the electrical conductivity of water in the study area. A geophysical survey was conducted through 34 Vertical Electrical Soundings (VESs) to calculate the water electrical conductivity from the... |

| The results obtained from the erpretation of the V.E.S.’s gave information regarding the geological situation in the Nuweiba Harbour, Gulf of Aqaba south Sinai, Egypt. A total of 20 vertical electrical soundings (V.E.S.’s) were conducted along 6 profiles. The geoelectrical field emphasis some knowledge about structural geology and lithology of the subsurface formations of the study area. In this work, the Schlumberger array with maximum current electrode half spacing (AB/2) of 75 m was applied. This spacing is sufficient to reach adequate depths for this study. The established geoelectric sections reveal the presence of the following geoelectric units: (a) A superficial unit characterized by electric resistivity value ranging from 2.47 to 106 ohm-m., and... |
