Seawater intrusion (SI) is a global issue, exacerbated by increasing demands for freshwater
in coastal zones and predisposed to the influences of rising sea levels and changing …

On atoll islands, fresh groundwater occurs as a buoyant lens-shaped body surrounded by
saltwater derived from the sea, forming the main freshwater source for many island …

Groundwater flow and chemical transport in subterranean estuaries are poorly understood
despite their potentially important implications for chemical fluxes from aquifers to coastal …

The biogeochemical reactivity of sandy beach aquifers is closely linked to physical flow and
solute transport processes. Thus, a clearer understanding of the hydrodynamics in the …

Studies of seawater intrusion in unconfined coastal aquifers typically neglect oceanic
oscillations such as tides and assume a static seaward boundary condition defined by the …

In this paper, we investigated the tide-induced seawater–groundwater circulation in shallow
beach aquifers using the finite element model MARUN. The numerical solutions were …

A parametric analysis is conducted to examine the influence of tides, inland hydraulic
conditions, and aquifer properties on the rate of tide‐induced seawater recirculation through …

Extended periods of below-average rainfall combined with a rising population density in the
Australian coastal margin have led to higher stresses on coastal water resources, and the …

Small‐island populations disproportionately rely on fresh groundwater resources, which are
increasingly threatened by salinization from changing ocean and climate conditions. This …

Surface water bodies connected to the ocean such as estuarine rivers can act as pathways
for saltwater intrusion (SI, ie, the displacement of fresh groundwater by saltwater in an …
