Groundwater dynamics in subterranean estuaries of coastal unconfined aquifers: Controls on submarine groundwater discharge and chemical inputs to the ocean

Sustainable coastal resource management requires sound understanding of interactions between coastal unconfined aquifers and the ocean as these interactions influence the flux of chemicals to the coastal ocean and the availability of fresh groundwater reso ...

Effects of episodic rainfall on a subterranean estuary

David Andrew Barry, Clare Robinson

Numerical simulations were conducted to examine the effect of episodic rainfall on nearshore groundwater dynamics in a tidally influenced unconfined coastal aquifer, with a focus on both long- (yearly) and short-term (daily) behaviour of submarine groundwa ...

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 ...

Memory of past random wave conditions in submarine groundwater discharge

David Andrew Barry, Clare Robinson

Submarine groundwater discharge (SGD) is an integral part of the hydrological cycle and represents an important aspect of land-ocean interactions. We used a numerical model to simulate flow and salt transport in a nearshore groundwater aquifer under varyin ...

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 ...

Transport of variable-density solute plumes in beach aquifers in response to oceanic forcing

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

A comprehensive numerical study was undertaken to investigate transport of a variable-density, conservative solute plume in an unconfined coastal aquifer subject to high and low frequency oceanic forcing. The model combined variable-density saturated flow ...

Analysis of acidity production during enhanced reductive dechlorination using a simplified reactive transport model

David Andrew Barry, Alessandro Brovelli, Clare Robinson

Build-up of fermentation products and hydrochloric acid at a contaminated site undergoing enhanced reductive dechlorination can result in groundwater acidification. Sub-optimal pH conditions can inhibit microbial activity and lead to reduced dechlorination ...

Effects of wave forcing on a subterranean estuary

David Andrew Barry, Roham Bakhtyar, Clare Robinson

Wave and tide are important forcing factors that typically co-exist in coastal environments. A numerical study was conducted to investigate individual and combined effects of these forces on flow and mixing processes in a near-shore subterranean estuary. A ...

Biological reduction of chlorinated solvents: Batch-scale geochemical modeling

David Andrew Barry, Clare Robinson

Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...
