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 …

Geological heterogeneity of the subsurface, caused by both discrete features and spatially
distributed hydraulic conductivity fields, affects the flow of coastal groundwater. It influences …

Laboratory scale experiments and numerical modelling were employed in this study to
investigate saltwater intrusion in fractured aquifers. Saline intrusion was initiated in one …

We propose a new concept that has the potential to mitigate seawater intrusion and increase
the fresh groundwater storage of oceanic islands by creating a less permeable slice along …

Freshwater lenses are of great importance in supporting both the vulnerable ecosystems of
small‐to‐medium oceanic islands and the lives of local inhabitants. Recently, an …

The drinking water supply on barrier islands largely depends on freshwater lenses, which
are also highly relevant for island ecosystems. The freshwater lens presented in this study is …

A novel methodology has been developed to quantify important salt water intrusion
parameters in a sandbox experiment using image analysis. Existing methods found in the …

Preferential flow can result in rapid contamination of groundwater resources. This is
particularly true in aquifers with connected, high permeability geologic structures and in …

Freshwater lenses (FWL) underneath islands are often unique freshwater resources.
Constructing cut-off walls in coastal islands to increase the FWL size has been proposed …

Previous sharp-interface studies of seawater intrusion (SWI) adopt various approaches to
the treatment of vertical fluxes in regions where alternating saltwater and freshwater are …
