Abstract
The groundwater resource is a problem that is becoming more difficult in the world,
particularly in Lebanon. The amount of groundwater in karst areas has been diminished due
to the global climate change, which has led to a decrease in the amount of rain. Lebanon,
which is considered the second Middle Eastern water tower risk for this major environmental
problem; especially in Beqaa , where annual rainfall amount does not exceed the threshold of
600 mm. Due to this shortage of rain, this region is about to know an acute water crisis in the
context of climate change. Therefore, it seemed interesting to focus on a case study to
represent this problem in Beqaa. The aim is to better identify natural variations in the
groundwater level in karst areas of this region due to the climate change.
Piezometric measurements in the fissure-karst area using a new monitoring well designed
personally helped first to characterize the overall hydrodynamic behavior of the karstic
aquifer and second to evaluate the hydrodynamic characteristics of the region. As an
outcome, the interpretation of the observed allowed us to graphically present the variations of
the underground water level of the test wells: which ended up to be a total dryness during
autumn. These results show the constraints that could prevent an effective policy to protect
the underground water in this area. In such a context, the implementation of proper
management of underground water in an area of semi-arid climate is crucial
