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.
HGS RESEARCH HIGHLIGHT – Heat Tracing in a Fractured Aquifer with Injection of Hot and Cold Water
In this comprehensive study, researchers explore the application of heat as a tracer in fractured porous aquifers, offering new perspectives on groundwater flow and transport dynamics.
