Since the beginning of 1980s, several regions in northern Sahara Algeria have been confronting rising groundwater. Among all these regions, Oued Souf Valley represented one most acute affected by this phenomenon. Due to natural topography and insufficient/weakness water management miscoordination between different sectors that are intensive exploitation deep groundwater reservoirs which returns...

Electric resistivity sounding and tomography, as well electromagnetic sounding, are the classical methods frequently used for hydrogeological studies. In this work, we propose development implementation of an original integrated approach using unconventional hydro–geophysical gravity seismic reflection fast, large–scale characterization potential Ain El Beidha plain (central Tunisia) analogue. ...

Agriculture is an important sector in Algeria, it the second economic component of country, however country suffers from water shortage and high soil permeability, especially Sahara region The area Algeria accounts for about 85% its total area, Algeria's considered as most arid world has a Leading to consume large quantities irrigation. In order solve these problems, hydrogels are effective sol...

Water erosion is a major problem in semi-arid region where decreases the dam reservoir design capacity, agricultural yield productivity, and increases other environmental impacts. This phenomenon widely predominant Morocco, particularly Oued El Malleh watershed Casablanca Settat region. Most soil happens gradually which makes it challenging to notice. Hence, monitoring of degradation under mode...
