Impact of recent climate variability on an aquifer system in north Belgium [PDF]

open access: yes, 2012
The last decade it has been realised that climate and global change can (and very likely will affect) groundwater reserves. This will have impact on both the economical (groundwater exploitation) and ecological (ecosystems) aspects of aquifer systems.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

The effect of using different time steps in a soil water balance model to estimate groundwater recharge in the dry zone of Sri Lanka [PDF]

open access: yes, 2010
Importance of groundwater as a natural, renewable resource is well documented. The rate of replenishment of water table (or rate of groundwater recharge) is a key issue central to sustainable development of this valuable resource.

Incorporating Electrostatic Coupling Effects into Multispecies Solute Transport Simulations with MODFLOW

open access: yesGroundwater, EarlyView.
Abstract Solute transport simulators aiming to accurately describe the transport of charged chemical species in porous media need to account for electrostatic coupling effects. Each ion in pore water possesses a specific electric charge and molecular diffusion coefficient, properties that determine their mobility and the overall charge balance of ...

Spatial Analysis to Determine Groundwater Recharge Area in Purworejo Regency, Central Java Province/Indonesia

open access: yesE3S Web of Conferences, 2018
The impact of land use change will lead to a reduction of the land that is supposed to be for the groundwater recharge area. The area which is previously as a protected area, becoming a cultivated area.

Potential Impacts of Climate Change and Variability on Groundwater Resources in Nigeria [PDF]

open access: yes, 2011
Climate change observed over the past decades has been consistently associated with modifications of components of the hydrological systems such as precipitation patterns, sea surface temperature, accelerated melting of glacier and ice caps, soil ...

Teach Me How to PyCap: A High‐Capacity Well Decision Support Tool Using Analytical Solutions in Python

open access: yesGroundwater, EarlyView.
Regulatory agencies in humid temperate environments rely on timely evaluations of streamflow depletion and drawdown to protect aquatic ecosystems and existing water users. We present an open‐source Python package implementing analytical solutions for estimating streamflow depletion and drawdown and supporting superposition of multiple wells and ...
