دراسات جيوكهربية لمنطقة ميناء نويبع جمهورية مصر العربيةAbstract
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 with a thickness ranges from 0.7 to 9.7 m. (b) A second unit with electric resistivity values (0.82 - 24 ohm-m.) and of depths from 0.35 to 5.8 m. (c) A third unit characterized by electric resistivity values ranging from 0.7 and 6.5 ohm-m. This third unit has a maximum thickness of 22m. which disappears at some localities. (d) A basal unit characterized by lower electric resistivity values that ranging from 0.2 to 0.6 ohm-m. Location for cathodic protection necessary for construction of civil engineering harbour project is determined by the lowest values of resistivity values.Journal
