Résumé :
|
In order to improve water supply of certain villages in the regions of KOLDA and ZIGUINCHOR, where existing resources are insufficient, the Directorate of Rural Hydraulics of the Ministry of Hydraulics of the Republic of Senegal has established a reconnaissance programme including a geophysical survey which was awarded to Compagnie de Prospection Géophysique Française under supervision by B.R.G.M This survey was funded by the Saudi Development Fund.The regions surveyed are located in Casamance:zones in lower Casamance :SEDHIOU,OUSSOUYE-ZIGUINCHOR,zone in upper Casamance :BIGNONA DIOULOULOU, VILINGARA A total of 31 villages were thus surveyed. The geophysical survey was carried out by use of electrical methods. These methods measure resistivities of different earth layers up to depths function of the measurement spread.303 resistivity soundings, 3 resistivity panels and 4 480 metres of resistivity profiles were carried out from January to April 1986. Depth of investigation varied from 100 to 200 m.
