Abstract

The results obtained from this study showed that the regions of Choueifat, Jiye and Rmeyle (Lebanon) are subject to seawater intrusion. This intrusion is directly and simultaneously related related to the pumping period and intensity but poorly related to the amount of rainfall. It also depends on the geologic nature of the study area. Furthermore, the actual intrusion in the study zone aggravates the existing salinity problems. Indeed the salinity rates of well water ranged between 0.7mS/m and 5.5 mS/m (the majority being above 2 dS/m9 reslting in salinity rates not tolerable for crops, thus threatening their growth and production. Moreover, the correlation analysis has highlighted the problem of seawater intrusion through the data that accompanied the study.
