Zusammenfassung: | Large overpopulated coastal areas are, nowadays, affected by seawater intrusion, and the contamination of the groundwater is a real threat. This paper aims to identify the zones along which seawater spreads in the Mt. Cameroon coastal region of Cameroon, and to map the most vulnerable areas to this threat. The results are based on the location of the contaminated boreholes, statistical analysis of automatic and manual lineaments, topographic and slope maps. The elaborated thematic maps allow identification of the fractured zones along which seawater can spread and the areas where the impact of this phenomenon could be more severe. The presence of a large number of contaminated coastal boreholes suggests that elevation ( |
