Assessment of modern irrigation versus flood irrigation on groundwater potentiality in old clayey lands

Summary:Groundwater management in semiarid and arid regions, like northern Egypt, is essential for the sustainability of scarce resources through monitoring groundwater status and sources of recharge to the aquifer. In the Qalyubia Governorate, Nile Delta, Egypt, the study examined the recharge of groundwater in lands subject to flood irrigation and compared it with water-saving irrigation methods to detect how irrigation practices influence the potentiality of groundwater. A simulation of the two irrigation techniques, flood irrigation, and water-saving irrigation, was performed. Using GMS, simulations are done to calculate the water balance in the main 8 districts of Qalyubia Governorate. In comparison to flood irrigation, it was found that water-saving irrigation has less recharge intensity, which in turn causes a lowering in groundwater levels. The decline in groundwater table ranges between 10 and 50 cm. Modern irrigation influences the potentiality of the Nile Delta aquifer, which can’t be underestimated.
