Effects of Unsaturated Flow on Salt Distributions in Tidally Influenced Coastal Unconfined Aquifers

Unsaturated flow influences both the seawater extent under steady-state conditions and the propagation of tides in coastal aquifers. However, its effects on salt distributions in tidally influenced coastal aquifers are little investigated. The present stud ...

Effects of groundwater on desalinization in coastal reservoir and adjacent aquifer

David Andrew Barry, Jing Xu

Coastal reservoir provides the additional storage capacity of freshwater in coastal zone which greatly alleviate the water shortage in stressed areas, and the salinization of reservoir water degrade the utility of coastal reservoir. Salinization may result ...

A Reassessment of of the geochemical and isotopic fidelity of biogenic carbonates

Anders Meibom, Jaroslaw Hubert Stolarski, Arthur Adams, Deyanira Graciela Cisneros Lazaro, Jinming Guo, Tarek Axel Vennemann

Oxygen isotope compositions of calcite foraminifera tests are considered to be a robust palaeotemperature proxy at earth-surface conditions, where diffusion is slow. Recrystallization of tests during diagenesis may be optically identified and is often the ...

Semi-analytical solution of flow to a well in an unconfined-fractured aquifer system separated by an aquitard

David Andrew Barry

Semi-analytical solutions are presented for flow to a well in an extensive homogeneous and anisotropic unconfined-fractured aquifer system separated by an aquitard. The pumping well is of infinitesimal radius and screened in either the overlying unconfined ...

Comment on “Origin of water in the Badain Jaran Desert, China: New insight from isotopes” by Wu et al. (2017)

David Andrew Barry, Jiaqi Chen

Precipitation isotope data were used to determine the origin of groundwater in the Badain Jaran Desert (BJD) in the study of Wu et al. (2017). Both precipitation and its isotope composition vary seasonally, so arithmetic averages of precipitation isotope v ...

Potential for Fault Reactivation Due to CO2 Injection in a Semi-Closed Saline Aquifer

Lyesse Laloui, Victor Vilarrasa Riano, Roman Makhnenko

CO2 injection in extensive saline aquifers that present no faults is unlikely to damage the caprock sealing capacity. In contrast, CO2 injection in closed reservoirs will induce a large pressure buildup that may reactivate the low-permeable faults that bou ...

Groundwater flow and salt transport in a subterranean estuary driven by intensified wave conditions

David Andrew Barry, Clare Robinson

A numerical study, based on a density-dependent variably saturated groundwater flow model, was conducted to investigate flow and salt transport in a near-shore aquifer under intensified wave conditions caused by offshore storms. Temporally varying onshore ...

Influence of tides and waves on the fate of nutrients in a nearshore aquifer: Numerical simulations

David Andrew Barry, Clare Robinson

A numerical investigation is presented that demonstrates the influence of tides and waves on the transport and transformation of nutrients (NO3-; NH4+; PO43-) in a homogeneous unconfined nearshore aquifer and subsequent fluxes to the sea. Simulations of an ...

Hydromechanical coupling in CO2 geological injection processes

Lyesse Laloui, Chao Li

CO2 storage in deep aquifers is considered as a potential technology to reduce the greenhouse effects of CO2. Practically, a large-volume (>1 Mt/year) of CO2 could be injected into a system that consists of a highly porous host aquifer covered by a low-per ...

Cross-shore transport pathways between coastal aquifers and coastal seas: Archetype of a nearshore variable-density contaminant plume

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar, Clare Robinson

On permeable beaches, tides and waves lead to an upper saline plume underneath the beach face in addition to the saltwater wedge. The transport and fate of land-derived chemicals depend on process dynamics at the land-sea interface, which can be examined u ...
