The Coastal Aquifer Test Field (CAT-Field) between Bremerhaven and Cuxhaven in the north of Germany (see Fig. 1) extends over an area of 1800 km. The center of the CAT-Field, a sandy geest ridge with high groundwater recharge, is surrounded by the extensive drained marsh area and the North Sea coast line. The aquifer consists of quaternary and tertiary sediments. A large quaternary channel syst...

A combination of geologic descriptions of cores, borehole geophysics, surfacegeophysical soundings and water-sample analyses was used to characterize flow in the surficial aquifer in the vicinity of Big Cypress National Preserve, Collier County, south Florida. The geophysical analysis augmented by aquifer tests and piezometer measurements showed that the surficial aquifer is under unconfined co...

The study site covers an area of 273 km in the Oristano plain on the western coast of central Sardinia (Italy). In the coastal area, since 1950, intensive agriculture and subsequent urbanization have resulted in overexploitation of the aquifer system and significant deterioration of groundwater quality due to seawater encroachment. The groundwater basin, hosted in the Quaternary alluvia release...

The unsaturated zone and the saturated/unsaturated interface region are important links between groundwater and the land surface. They provide storage capacity for both water and contaminants; a reactor medium for physical, chemical and biological processes; a delay time between the release of a contaminant into the unsaturated zone and its influx into the saturated zone and, a domain for the l...

[1] In many coastal areas, land has been reclaimed by dumping fill materials into the sea. Land reclamation may have a significant effect on groundwater regimes, especially when the reclamation is at large scale. Analytical studies on the impact of land reclamation on steady-state ground water flow conditions were conducted previously, but transient analytical solutions are not yet available. T...

This paper presents the development and application of a conjunctive water management model for lowland catchments. The model incorporates a simulation model and a management model to simulate groundwater movement, ground consolidation and to search for the potential pumping amount of groundwater without violating physical and environmental constraints. The results reveal that groundwater level...

Abstract Coastal aquifers provide water for over one billion people worldwide; however, they face seawater intrusion due to overpumping. The current and future challenges of coastal aquifer management involve issues such as climate change the control abstraction recharge. Different approaches are being used globally prevent salinization. This essay presents possible solutions while also discuss...
