A large fraction of the fresh water available for human use is stored in groundwater aquifers. Since human activities such as mining, agriculture, industry and urbanisation often result in incursion of various pollutants to groundwater, routine monitoring of water quality is an indispensable component of judicious aquifer management. Unfortunately, groundwater pollution monitoring is expensive ...

Saltwater intrusion is an ideal target for mapping with airborne electromagnetic techniques because of the high electrical conductivity of saline water and its contrast with that of freshwater. Using electromagnetic sensors to measure the electromagnetic response of the ground at several frequencies, information from various depths is obtained. The electromagnetic response is then converted to ...

This paper presents an analytical model characterizing unsteady groundwater flow in an unconfined aquifer resting on a sloping impervious bed. The aquifer is in contact with a constant water level at one end. The other end is connected to a stream whose level is increasing form an initial level to a final level at a known exponentially decaying function of time. Moreover, the aquifer is repleni...

The Mikkes basin is located at the north center of Morocco. It comprises three different zones which represent diversified geologies which shelter a phreatic and confined aquifer in the Sais basin and a shallow aquifer in the Tabular Middle Atlas. The springs in the Sais phreatic aquifer have suffered a maximum depletion. The springs with a deep or mixed origin are known as low flow variation s...

This dissertation investigates the application of interferometric synthetic aperture radar (InSAR) to the measurement and interpretation of surface displacements over developed aquifer systems. Land subsidence over developed groundwater systems has been observed in a wide variety of hydrogeologic settings worldwide. The phenomenon can be explained with elastic and inelastic deformation of water...

Local groundwater in coastal aquifers in Shenzhen has experienced heavy pumping since the 1980’s when Shenzhen began to expand very quickly from a fishing village to a modern city but lacked a public water supply. Meanwhile, large-scale land reclamation was carried out to meet the needs of various urbanization projects. In this paper we analyzed groundwater from a coastal aquifer system in Shen...

Watertable waves generated by forcing from oceanic oscillations play an important role in the availability and quality of coastal groundwater resources. Here we present results from laboratory experiments which examine the influence of a boundary slope on the mass transfer from an oscillating clear water reservoir into a homogeneous, unconfined aquifer. The experimental forcing period is suffic...
