Aquifer storage and recovery, and managed aquifer recharge of reclaimed water for management of coastal aquifers

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.

Estimation of Aquifer Diffusivity in Stream-Aquifer Systems

Journal of the Hydraulics Division, 1977
By 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

A Leaky Aquifer Model For Hard Rock Aquifers

Hydrogeology Journal, 1994
A 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.

Aquifer parameter prediction in leaky aquifers

Journal of Hydrology, 1985
Abstract 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

2019
ABSTRACT 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

2021
The 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 ...
