Sixty years of global progress in managed aquifer recharge
Hydrogeology Journal, 2018 The last 60 years has seen unprecedented groundwater extraction and overdraft as well as development of new technologies for water treatment that together drive the advance in intentional groundwater replenishment known as managed aquifer recharge (MAR).

Rivers Research and Applications: an international journal devoted to river research and management, 2019
Recently, many studies have investigated the effect of climate change on groundwater resources in semiarid and arid areas and have shown adverse effects on groundwater recharge and water level.

DESALINATION AND WATER TREATMENT, 2020
The hydrological and economic feasibility of aquifer storage and recovery (ASR) of excess desali-nated water and managed aquifer recharge (MAR) using tertiary treated wastewater (TTWW) to manage stressed coastal aquifers in Oman has been studied numerically using the code, MODFLOW 2005 and the different transport packages MT3DMS, and MODPATH.

A Leaky Aquifer Model For Hard Rock Aquifers
Hydrogeology Journal, 1994A comparison is made between the unsteady parallel fracture model using the double porosity approach and the anisotropic aquifer-water table aquitard system. The presence of a moving water table in the weathered zone (unconfined block), influenced by recharge from rainfall or other sources and leakage to the fracture zone, is discussed.

Estimation of Aquifer Diffusivity in Stream-Aquifer Systems
Journal of the Hydraulics Division, 1977By specifying an extra boundary condition in terms of hydraulic gradient at the stream-aquifer interface, and using the Green’s function of the linearized Boussinesq equation, analytical solutions have been developed to determine aquifer diffusivity explicitly. Four different types of Dirichlet boundary condition describing stream gage hydrographs have

Virtual Water, 2018
The only means of moderating alarming depletion rates in many of the world’s major aquifers is to reduce pumping. We apply a new water-balance approach to assess the impact of pumping reductions in a portion of the High Plains aquifer in the United ...

Aquifer parameter prediction in leaky aquifers
Journal of Hydrology, 1985Abstract The finite element—least-squares optimization algorithm is utilized to identify the hydrogeologic field parameters of a multi-layer aquifer system. The technique developed relies on accurate steady state piezometric head data for each aquifer in the multi-layered system.

Aquifer storage and recovery in the Edwards Aquifers, Texas
2019ABSTRACT Aquifer storage and recovery (ASR) is a proven water-supply strategy that uses an aquifer to store surplus water that will be available for later use when that stored water is needed. Although only three ASR systems are currently operating in Texas, recent incentives from the state, along with changes in regulatory framework ...

The International Agreement of the Guarani Aquifer System: A Transboundary Aquifer
2021The hydrogeology associated with Environmental Law is essential in the discussion of transboundary aquifer management. The “Guarani Aquifer Agreement”, although not yet in force, presents the instruments for shared management of the Guarani Aquifer System (SAG), located in parts of the territories of Argentina, Brazil, Paraguay and Uruguay countries ...

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2006, 2006
In this presentation, we discuss geophysical methods for general vulnerability mapping of aquifers. The vulnerability of aquifers is to a large degree determined by the content of clay minerals in the near surface geology. Clay minerals have a large cation exchange capacity (CEC) and clayey sediments reduce the infiltration speed thus reducing the ...
