HGS RESEARCH HIGHLIGHT - Mega-Tidal and Surface Flooding Controls on Coastal Groundwater and Saltwater Intrusion Within Agricultural Dikelands

The study highlighted here makes full use of the density dependent flow modelling capabilities of HydroGeoSphere to investigate the impacts of climate change on groundwater-ocean interactions, and how sea-level rise, tides and storm-surges impact the long-term position of an upper saline plume in a coastal agricultural dikeland in Nova Scotia, Canada.

HGS RESEARCH HIGHLIGHT – Groundwater flow reversal between small water bodies and their adjoining aquifers: A numerical experiment

This recent study uses HydroGeoSphere to investigate groundwater-surface water interactions within “kettle holes” - post glacial landscape features prevalent across Northern Europe and Northern America. These kettle holes are quite similar to lakes, but their smaller size makes them prone to drying out, which results in very dynamic and variable groundwater-surface water interactions, sometimes being subject to groundwater flow reversal between a kettle hole and the adjacent aquifer.

HGS RESEARCH HIGHLIGHT – Evaluation of Hydraulic Conductivity Estimates from Various Approaches with Groundwater Flow Models

Over several decades a wide variety of techniques have been used to estimate the hydraulic flow properties of the subsurface. Here the authors have produced heterogeneous hydraulic conductivity (K) distributions at a heavily instrumented research site using 6 distinct techniques (slight variations in some tests resulted in 9 distinct K distributions):.

HGS RESEARCH HIGHLIGHT – Managing climate change impacts on the Western Mountain Aquifer: Implications for Mediterranean karst groundwater resources

A new study investigates the impact of climate change on water availability within a 9000 sqkm karstic aquifer in Israel and the West Bank, and couples HydroGeoSphere to a soil-epikarst water balance model.
