Hydrodynamic behaviour of the seawater-freshwater mixing zone induced by cutoff wall installation in sloping coastal aquifers

Asaad M. Armanuos, Kristián Mičko, Marcela Bindzárová Gergeľová, Martina Zeleňáková

Sustainable groundwater management depends on understanding the dynamic behaviour of seawater intrusion (SWI), a slow and persistent phenomenon that might go on for decades in coastal aquifers. A crucial element in regulating groundwater flow and solute transport in coastal aquifers is the …

Integrated assessment of irrigation canal lining and covering impacts on groundwater dynamics in the central Nile Delta, Egypt

Huda M. Abd-Elrazak, Tamer A. Gado, Asaad M. Armanuos

Abstract The rehabilitation of irrigation canals may reduce conveyance losses but also diminish recharge to shallow aquifers. One significant source of irrigation canal water loss is seepage. Determining the possible advantages of employing seepage reduction technology and materials requires quantifying the seepage …

Hydrodynamic effects of underground dams on seawater–freshwater mixing zone in sloping beach coastal aquifers

Asaad M. Armanuos, Martina Zeleňáková

Abstract Seawater intrusion (SWI) is a continual challenge that threatens the sustainability of coastal groundwater resources. The behaviour of the seawater-freshwater mixing zone plays a critical role in controlling groundwater quality and solute transport; however, the combined impact of underground dams and …

Performance Drop Appraisal of a Dual-Fracture Underground Barrier for Mitigating Coastal Aquifer Salinization

Asaad M. Armanuos, Ahmed Shalby, Sobhy R. Emara

Abstract Saltwater intrusion (SI) increasingly jeopardizes coastal aquifers, causing soil and groundwater salinization. Subsurface dams are commonly installed at the aquifer base to counteract SI. They have proven to be highly effective mitigation measures, albeit costly. However, such concrete dams often imply …

Assessing the effect of heterogeneous land reclamation on saltwater intrusion into unconfined coastal aquifers

Mahmoud Abd-Elsattar, Ibrahim M. H. Rashwan, Asaad M. Armanuos, Sobhy R. Emara

Abstract Several aquifers worldwide are vulnerable to the serious problem of saltwater intrusion (SI). Groundwater pumping, irregular sea level, and global warming increase SI. Protecting the coastal aquifers is essential, as coastal regions consider groundwater systems to be major freshwater sources. This …
