This unique volume offers an up-to-date overview of all the main aspects of groundwater in the Nile Delta and its fringes, as well as latest research findings. The themes covered include:

· Nile Delta aquifer formation and its characteristics

· The use of the groundwater in the Nile Delta and its implications

· Sedimentology and hydrogeophysical characteristics

· Groundwater investigations and aquifer characterization using current direct resistivity and induced polarization

· Groundwater contamination and degradation · Saltwater intrusion and its control · Delineation of groundwater flow and seawater intrusion using various techniques, including one-dimensional subsurfacetemperature profiles, geoelectrical resistivity, and integrated subsurface thermal regime and hydrogeochemical data

· Modeling of groundwater and of saltwater intrusion in the Nile Delta aquifer

· Excessive pumping and groundwater quality assessment for irrigation and drinking purposes · Groundwater management for sustainability in the Nile Delta. The volume appeals to postgraduate students, researchers, scientists, professionals, decision makers and planners.

Sheds new light on the challenges related to Egypt's groundwater, which represents the second largest freshwater resource after the river Nile Presents a comprehensive review Appeals to environmental managers, scientists and policymakers
