Abstract
Contaminant plume mapping, depth to bedrock profiling, channel mapping, and other useful geophysical data sets are nowadays routinely provided to resource and contaminant hydrogeologists. However, until recently, the ability to provide depth specific hydraulic properties, with confidence, and especially in complex geological environments, has been lacking. Recent developments in both surface, downhole, and even drone-based methods now allow geophysicists to provide detailed measurements, with depth, of hydraulic conductivity, total water content, bound water content, free water content, transmissivity, and fracture flow characterization. Distributed temperature sensing (DTS) and thermal imagery from drones is now routinely used for identifying groundwater discharge zones. Specific applicable methods with field examples to be discussed include nuclear magnetic resonance, high resolution temperature logging, acoustic and optical televiewer logging, DTS, heat pulse flowmeter logging, cross-hole resistivity, and thermal mapping from drones.
Biography
Paul Bauman is the Technical Director of the Near Surface Geophysics group at WorleyParsons, in Calgary, Alberta, Canada. Paul started the group in 1990, and has since managed or co-managed the group. Paul is a Professional Geophysicist and Professional Engineer with over 30 years of geophysical exploration experience in the environmental, engineering, water resource, mining, oil and gas, and archaeology sectors. Paul has a B.Sc.E. in Geological Engineering from Princeton, and an M.Sc. in Earth Sciences from the University of Waterloo. Of particular note is his recent refugee water supply work in Africa, and various archaeogeophysical projects which have been featured in a number of movies including the National Geographic Television special Finding Atlantis, two NOVA documentaries (Ancient Refuge in the Holy Land and Holocaust Escape Tunnel), and the documentary Deadly Deception at Sobibor.
