Invasion saline au niveau de la nappe côtière Lota - Souk El Tenine

Abstract

In recent years, coastal areas have developed a strong demographic, leading to an intensification of needs in all areas, which reflected directly on water resources, especially as coastal water tables do not have significant extensions. It is for this reason that we have chosen to study the saline invasion at the level of the coastal plain of Souk el Tenine.The combination of geological, geophysical, hydrogeological, piezometric and hydrochemical tools, as well as the use of mapping methods of major elements and conductivity, showed the origin of the salinity. The results of our study showed the low concentration of the major elements in the groundwater which is probably due to the leaching of the formations traversed. Using these different approaches, we have demonstrated that there is no saline invasion in the region studied. This is likely to be the result of good water management by the responsible authorities.
