Title: Hydrogeophysical methods for soil and aquifer characterization: current industry practices vis-a-vis state of the art.
The need to ensure the safety of engineering structures on the shallow subsurface; the drive for sustainable agricultural to ensure food security; the increasing demand for clean water; the challenge of protecting soil and groundwater resources from contamination; the determination of soil and groundwater contamination legacy due to industrial and agricultural activities; the remediation of contaminated soils and aquifers and the need to understand the interaction and impact of water resources on the ecosystem are some of the challenges demanding an improved understanding of the structure and processes within soils and aquifers in the shallow subsurface. Hydrogeophysics provides a suite of techniques that may be use to characterize the subsurface structure, estimate its flow and transport parameters and as well monitor the state and variability of processes within it. While hydrogeophysical research in the last decades has evolved from simply combining hydraulic well testing and geophysical measurements to the interdisciplinary integration of methods to aid in the parameterization of subsurface flow and transport models and better monitoring of hydrogeological and biogeochemical systems, a review of current industry practice shows a wide gap in the transfer of scientific know-how to addressing the aforementioned challenges. In this talk, some research and industry based examples are presented to show this gap and challenge the community to increase efforts towards closing it.
