HGS RESEARCH HIGHLIGHT – The effects of land subsidence and its mitigating measures on shallow groundwater salinization in the low-lying coastal plain of East Japan
The research investigates how land subsidence and mitigation measures, specifically pumping stations and ditch systems in Shirako Town, Japan's lower Nabaki River region, interact. Land subsidence, caused by natural and human factors, heightens flood risks in coastal areas, challenging infrastructure stability and environmental sustainability. While pumping stations and ditches aim to manage surface water levels and reduce floods, their impact on groundwater salinity near tidal rivers is unclear. Using a coupled surface-subsurface model, the study reveals potential risks like saline water intrusion into groundwater.

As an extension of the last HGS research highlight titled ‘Improving control of contamination from waste rock piles’, this next research highlight within this series looks at a study conducted by the same researchers and explores the effects of thin cover deposition on managing water table levels in acidic tailings impoundments, while utilizing HydroGeoSphere (HGS) for in-depth simulations.
HGS RESEARCH HIGHLIGHT – Improving control of contamination from waste rock piles
This study conducted by researchers investigates how well compacted cover layers on waste rock piles can mitigate infiltration into these waste piles, reducing the overall potential for oxidation of sulfidic waste materials and control environmental contamination. The research provides a detailed examination of how different cover configurations and hydrogeological conditions affect the performance of these covers in mitigating risks associated with waste rock piles.
HGS RESEARCH HIGHLIGHT – Assessing the impact of surface water and groundwater interactions for regional-scale simulations of water table elevation
In this research highlight, researchers Hugo Delottier, Oliver S. Schilling, and René Therrien, conducted an in-depth exploration of how the interaction between surface water (SW) and groundwater (GW) affects the accuracy of regional-scale simulations of water table elevations in Southern Quebec. This investigation was conducted over a vast 36,900 km² regional aquifer system, which is marked by a complex hydrogeological setup. The area of study includes a regional bedrock aquifer that is overlain by discontinuous Quaternary sediments, presenting a challenging environment for accurate hydrological modelling.
