Groundwater Science + Sustainability Research Group
Browse by
UVic's Groundwater Science and Sustainability (GSAS) research group integrates geomatics, numerical modelling, field hydrogeology, geochemistry, structural geology and sustainable science. We are engineers and geoscientists from around the world, as you can see on the people page. For more information see: http://www.groundwaterscienceandsustainability.org/

Recent Submissions
-
(Hydrogeology Journal, 2017)Permeability is the dominant parameter in most hydrogeologic studies. There is abundant evidence for dynamic variations in permeability in time as well as space, and throughout the crust. Whether this dynamic behavior ...
-
(Advances in Water Resources, 2019)Global food demand is projected double by 2050 ( Gerland et al., 2014 ; United Nations 2015 ; Godfray et al., 2010 ; Foley, 2015 ; Licker et al., 2010 ) significantly increasing freshwater consumption ( Bruinsma, 2009 ; ...
-
(Advances in Water Resources, 2017-04)Groundwater is the world’s largest accessible source of freshwater to satisfy human water needs. Moreover, groundwater buffers variable precipitation rates over time, thereby effectively sustaining river flows in times of ...
-
(Geofluids, 2014)In polyorogenic regions, the superposition of structures during a protracted tectonic history produces complex fractured bedrock aquifers. Thrust-faulted regions, in particular, have complicated permeability patterns that ...
-
(Water, 2014)Groundwater depletion poses a significant threat in arid and semi-arid areas where rivers are usually ephemeral and groundwater is the major source of water. The present study investigated whether an effective water resources ...
-
(Geofluids, 2015)Fluid circulation in the Earth's crust plays an essential role in surface, near surface, and deep crustal processes. Flow pathways are driven by hydraulic gradients but controlled by material permeability, which varies ...
-
(Geoscientific Model Development, 2015)Karst develops through the dissolution of carbonate rock and is a major source of groundwater contributing up to half of the total drinking water supply in some European countries. Previous approaches to model future water ...

-
(Climate of the Past, 2015)Reconstructions of Quaternary climate are often based on the isotopic content of paleo-precipitation preserved in proxy records. While many paleo-precipitation isotope records are available, few studies have synthesized ...
-
(Geofluids, 2016)Co-located and integrated observation of the surface and subsurface is necessary to characterize fault zone hydrogeology. The spectacular cliff-face exposure of the Champlain Thrust fault at Lone Rock Point, Vermont, and ...
-
(Geophysical Research Letters, 2017-05)The turnover of groundwater through recharge drives many processes throughout Earth’s surface and subsurface. Yet groundwater turnover rates and their relationship to regional climate and geology remain largely unknown. ...
-
(Geofluids, 2015)The permeability of sediments is a major control on groundwater flow and the associated redistribution of heat and solutes in sedimentary basins. While porosity–permeability relationships of pure clays and pure sands have ...
-
(Nature Communications, 2017-05-30)Water is a fundamental resource, yet its spatiotemporal availability in East Africa is poorly understood. This is the area where most hominin first occurrences are located, and consequently the potential role of water in ...
-
(Geofluids, 2014)The permeability of crystalline rocks is generally assumed to decrease with depth due to increasing overburden stress. While experiments have confirmed the dependence of permeability on stress, field measurements of ...
-
(Hydrology and Earth System Sciences, 2016-05-31)In the current human-modified world, or Anthropocene, the state of water stores and fluxes has become dependent on human as well as natural processes. Water deficits (or droughts) are the result of a complex interaction ...
-
A glimpse beneath earth’s surface: GLobal HYdrogeology MaPS (GLHYMPS) of permeability and porosity (Geophysical Research Letters, 2014)The lack of robust, spatially distributed subsurface data is the key obstacle limiting the implementation of complex and realistic groundwater dynamics into global land surface, hydrologic, and climate models. We map and ...
-
(Journal of Geophysical Research: Solid Earth, 2014-01)The permeability of fault zones impacts diverse geological processes such as hydrocarbon migration, hydrothermal fluid circulation, and regional groundwater flow, yet how fault zones affect groundwater flow at a regional ...
-
(Water Resources Research, 2014)Groundwater recharged by meteoric water supports human life by providing two billion people with drinking water and by supplying 40% of cropland irrigation. While annual groundwater recharge rates are reported in many ...
-
(Water Resources Research, 2014)A number of aquifers worldwide are being depleted, mainly by agricultural activities, yet groundwater stress has not been explicitly linked to specific agricultural crops. Using the newly developed concept of the groundwater ...
