Advancing Geological Realism in Groundwater Hydrology: Building on the Work of Graham Fogg
Session ID#: 249410
Session Description:
This session will highlight advances in groundwater hydrology made possible through the realistic representation of geology, as exemplified by the pioneering work of Professor Graham Fogg. Geological complexity can govern flow, reactive transport, and groundwater–surface water interactions, yet remains difficult to fully characterize and incorporate into hydrologic models. Emerging methods—including advanced geologic and geochemical characterization, geostatistical approaches, and improved transport modeling techniques for highly heterogeneous systems—have significantly enhanced our ability to simulate water and solute fluxes. These advancements have improved understanding of processes such as dispersion, aquifer remediation, and groundwater vulnerability, while also informing assessments of long-term water resource sustainability. This session will emphasize the importance of geologic realism in hydrogeologic modeling, decision-making, and the integration of science into policy and water resource management, particularly in the context of addressing future challenges to water quality and availability.
