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.

HGS RESEARCH HIGHLIGHT – Hydraulic Tomography Estimates Improved by Zonal Information From the Clustering of Geophysical Survey Data
Exploring innovative methods in groundwater characterization, Chenxi Wang and Walter A. Illman present a study on improving Hydraulic Tomography (HT) estimates through the integration of geophysical survey data. Hydraulic tomography offers valuable insights into subsurface heterogeneity by analyzing multiple pumping tests. However, challenges arise when insufficient observations lead to smooth or inaccurate tomograms. In this study, Wang and Illman investigate the integration of geophysical survey data into HT analysis to address this issue.
