Assessment of Salt-Water Wedge in the Artesian Egyptian Nile Delta Aquifer Lands Using Remote Sensing and Geophysical Techniques.

Abstract

Since the past century, a decline in climate changes rate has been observed, especially along the coastal plains. These changes led to a rise insea water whichremarkably affectedthe coastal zone. The increase of sea water is causing an increment in the water-logged and salt-affected areas. On the other hand, these water-logged and salt-affected areas affected crop productivity and sustainable development acrossthe coastal zones. In this paper, a cost-effective approach will be deployed to monitor the water-logged areas and give recommendations to overcomethis problem. This approach will depend on the joint usage of Remote Sensing data to monitor the surface waterlogged areas together with the geo-electrical techniques results to detect the subsurface salt-affected zones. This precise determination for these areas can help to give recommendations to face this problem. This approach can be applied to all coastal zones around the Arabic countries that are facing the effects of the climate change problem. The results indicated that groundwater quality in this region could be severely impacted by the effects of sea level rise combined with changes in the Nile flow, leading to increased groundwater salinity.
