A desktop study of the groundwater resources of Cousine and Cousin Islands, Seychelles : Funded by MSP GEF and prepared for Nature Seychelles
(Flinders University, 2007-12)The groundwater resources of Cousine and Cousin Islands has previously not been investigated, although these resources are accessed via bore pumping to support tourism, residents, and visitors to the islands, in terms of ... -
Using geochemistry to discern the patterns and timescales of groundwater recharge and mixing on floodplains in semi-arid regions
(Elsevier, 2019-01-24)Floodplains may alternate between discharge zones for regional groundwater and areas of recharge from river water during high-flow events. Understanding the mechanisms and timescales of recharge on floodplains is important ... -
Combined geophysical and analytical methods to estimate offshore freshwater extent
(Elsevier, 2019-06-22)Offshore fresh groundwater is increasingly suggested as a potential water resource for onshore human demands. In many cases, onshore pumping already draws significant fresh groundwater from offshore. However, offshore ... -
Dispersion effects on the freshwater–seawater interface in subsea aquifers
(Elsevier, 2019-05-29)Recent recognition of the widespread occurrence of freshwater beneath the ocean has renewed interest in approaches to understand and predict its extent. The most straightforward methodologies are based on the sharp-interface ... -
Rebuttal to “The case of the Biscayne Bay and aquifer near Miami, Florida: density-driven flow of seawater or gravitationally driven discharge of deep saline groundwater?” by Weyer (Environ Earth Sci 2018, 77:1-16)
(Springer, 2018-10-11)A recent paper by Weyer (Environ Earth Sci 2018, 77:1–16) challenges the widely accepted interpretation of groundwater heads and salinities in the coastal Biscayne aquifer near Miami, Florida, USA. Weyer (2018) suggests ... -
A conceptual study of offshore fresh groundwater behaviour in the Perth Basin (Australia): Modern salinity trends in a prehistoric context
(Elsevier, 2018-10)Fresh groundwater is thought to occur off the coast of Perth, Western Australia, in the confined Leederville and Yarragadee aquifers. Onshore hydraulic heads suggest that offshore groundwater may be augmenting onshore ... -
Boundary condition nomenclature confusion in groundwater flow modelling
(Wiley, 2019-04-18)To solve the partial differential equations of groundwater flow, the information about head (h) and/or head gradient (∇h) must be specified along the boundaries of a model domain. The descriptors of different boundary ... -
Efficacy and Efficiency of Multivariate Linear Regression for Rapid Prediction of Femoral Strain Fields during Activity
(Elsevier, 2018-12-11)Multivariate Linear Regression-based (MLR) surrogate models were explored to reduce the computational cost of predicting femoral strains during normal activity in comparison with finite element analysis. The musculoskeletal ... -
Transport and fate of viruses in sediment and stormwater from a Managed Aquifer Recharge site
(Elsevier, 2017-10-27)Enteric viruses are one of the major concerns in water reclamation and reuse at Managed Aquifer Recharge (MAR) sites. In this study, the transport and fate of bacteriophages MS2, PRD1, and ΦX174 were studied in sediment ... -
Evaluation of management scenarios for potable water supply using script-based numerical groundwater models of a freshwater lens
(Elsevier, 2019-02-20)Challenges in balancing freshwater demands and the long-term availability of freshwater from small island aquifers warrants responsive management, whereby groundwater conditions guide decisions about pumping rates to avoid ... -
The role of surface charge and pH changes in tropical soils on sorption behaviour of per- and polyfluoroalkyl substances (PFASs)
(Elsevier, 2019-04-05)This study investigated the effect of surface charge on the sorption of perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) onto 7 tropical soils as a function of ... -
Groundwater chemistry and the Gibbs Diagram
(Elsevier, 2018-08-09)The ‘Gibbs Diagram’ represents some of the key processes controlling surface water chemistry. This review highlights that the processes listed on the Gibbs Diagram may not be applicable for assessing processes controlling ... -
Development of an integrated model for the Campaspe catchment: a tool to help improve understanding of the interaction between society, policy, farming decision, ecology, hydrology and climate
(International Association of Hydrological Sciences, 2018-06-05)Management of water resources requires understanding of the hydrology and hydrogeology, as well as the policy and human drivers and their impacts. This understanding requires relevant inputs from a wide range of disciplines, ... -
Impacts of Different Onset Time El Niño Events on Winter Precipitation over South China
(MDPI, 2018-09-20)Winter precipitation over South China tended to be much higher than normal for the spring El Niño events during 1979–2016. For the spring El Niño events, the meridional and zonal circulations served as a bridge, linking ... -
Examination of the ecohydrological separation hypothesis in a humid subtropical area: Comparison of three methods
(Elsevier, 2019-02-18)The ecohydrological separation between soil water sources for plant water uptake and groundwater recharge has been recently examined in various climate zones primarily based on isotopic composition of water. The existence ... -
Uncertainty analysis for seawater intrusion in fractured coastal aquifers: Effects of fracture location, aperture, density and hydrodynamic parameters
(Elsevier, 2019-02-04)In this study we use polynomial chaos expansion (PCE) to perform uncertainty analysis for seawater intrusion (SWI) in fractured coastal aquifers (FCAs) which is simulated using the coupled discrete fracture network (DFN) ... -
Urban Land Systems: An Ecosystems Perspective
(MDPI, 2018-01-11)We live in an urbanizing world. Since 2008, more than half of humanity lives in cities, both large and small, and old and new. We also live in a world that is becoming even more urbanized, it is expected that by 2050, 66 ... -
