Applied Geophysics for Engineers -Theory, Measurements and Processing
Applied Geophysical techniques provide a range of engineering and scientific solutions to engineers in various fields who deal with the investigation, assessment, characterization and monitoring of subsurface earth materials. The range of problems encompass environmental, geotechnical, highways, mining, hydrocarbon exploration and exploitation, agriculture and forensic science and engineering issues. In all categories, applied geophysics provide a non-destructive, cost-effective and faster ways of achieving solutions or obtaining information needed by the engineer to solve them
The course will serve the needs of students, engineers and other professionals who:
- need to learn how geophysics contributes to finding solutions to specific geoscience problems in engineering, environment management, resource exploration etc., and
- are interested in the details about how applied geophysics works
The course will provide overviews needed to understand the physical principles behind geophysical methodologies, which methods will do what and where they fail and why, and what useful engineering information can be gleaned from the geophysical methods and what are the limitations and boundaries of interpretation. More importantly, the course will provide to participants a wide overview of how we integrate the geophysical techniques in a truly effective way to solve subtle, complex and critical problems which one technique alone cannot solve.
In modern times, engineers are confronted with challenging facing humanity and society. The course program will address variety of issues, challenges and problems that engineers face today in solving engineering and societal issues. These include identified areas some of which arise from conflicting interests in engineering technology and society and include:
Characterizing aquifer dynamics in the Western US
Exploring for water for the 20% of Earth’s population that lacks it
Characterizing agricultural soils, assessing irrigation in precision agriculture
Exploring and developing oil and gas, coal, coal bed methane, geothermal
Investigating sites for subsurface construction, tunneling
Locating and characterizing underground infrastructure and utilities
Exploring for mineral resources and characterizing in situ and mine leach processes
Monitoring, non-invasively, the utility infrastructure: natural gas, water, telecommunications, roads, railroads
Isolating toxic (nuclear, chemical) waste, acid mine drainage, waste pollution
Locating land mines and unexploded ordnance (UXO)
Monitoring, forecasting, and mitigating risks associated with landslides, earthquakes, volcanoes, avalanches, tsunamis.
Applications of geophysics to understand the effect of long term fertilization and tillage on soil properties and water retention capacity. Precision agriculture/farming
Using non-invasive methods to locate subsurface sites/structures/artifacts
Learning Outcomes of Course
Participants of the course, after completion, will be able to:
- understand the physical and theoretical basics behind each of the major geophysical techniques;
- understand when these basics can be best applied to engineering problems;
- collect data using geophysical equipment for geophysical investigations and assessments;
- reduce, process, and interpret geophysical data using up-to-date techniques and computer software;
- communicate effectively results from data acquisition and interpretation across an interdisciplinary environment;
- appreciate the interaction of engineering technology and society and the issues that arise from conflicting interests in this interaction
Who Should Attend?
Practicing engineers, consultants, geologists, drillers, engineering geologists, archaeologists, agricultural scientists and engineers and others professionals responsible for development or evaluation of site characterization studies, monitoring the subsurface, assessing properties of soils, that might benefit from the application of modern geophysical techniques. Faculty and students will learn methods that could be applied to cross-disciplinary research.
The course program will consist of two parts or modules: the first part will consist of overview of geophysical methods, understanding the principles involved in these methodologies, acquisition, processing and interpretation of measured geophysical data. The second part will consist of studies, discussions and analyses of a variety of case histories which will demonstrate practical use of geophysics spanning from; on-site assessment of infrastructure, precision agriculture, hydrologic monitoring, and environmental investigations, groundwater exploitation and exploration, foundation studies.

Changes in geomechanical properties of oil fields providing clues in the fluid flow within the reservoirs which helps geoscientists and reservoir engineers to plan for Enhance Oil Recovery.
In order to better resolve targets especially in areas where reconnaissance geophysics has indicated useful targets may exist, we need to emphasize the use of well chosen borehole techniques using both drilled borehole and push techniques. These include Borehole radar, Self–potential and electrical resistivity as well as, of course, cross-hole seismic tomography.
