Impact of Modern Irrigation Methods on Groundwater Storage and Land Subsidence in High-water Stress Regions

Abstract Water resources management in high-stress regions is a large-scale problem affecting food and water security. Therefore, modern irrigation systems such as sprinklers, subsurface, drip irrigations are applied to manage the shortage of Nile delta. Because increase population rate climate change, freshwater supplies significantly limited must be efficiently managed. Consequently, Egypt plans implement MIS old land The current study aims investigate model recharge from excess system that affects groundwater storage subsidence unexpectedly. visual modflow was heads drawdown. At same time, analytical solution based on Terzaghi theory, surfer software used estimate map subsidence. For this reason, we investigated drawdown high-water Egypt’s Three scenarios were considered by changing methods their Impact Delta Aquifer (NDA). results demonstrated reached 2.60 m, 4.20 6.50 respectively. In contrast, outstretched 26 44 65 cm for sprinkle sub-surface. Future design infrastructures pipelines, roads, networks, canals, structures should consider due (MIS).
