Engineering Geophysics (eBook, ePUB)

Redaktion: Bondo Medhus, Anna; Klinkby, Lone

• Format: ePub

Produktbeschreibung

Engineering Geophysics connects onshore geotechnical engineering challenges to the geophysical methods that may be applied to solve them. Unknown geological conditions are a risk in construction projects, and geophysical information can help to identify those risks. The book answers questions on how, why, and when the individual and combined methods provide the results requested. Flowcharts guide the reader to geophysical methods that can be applied for various engineering challenges, and the solutions are illustrated with practical case histories.

The book is intended mainly for geotechnical engineers and geologists but also for geophysicists or managers in need of an overview or brushup on geophysical methods and their practical applications. In addition, it can be used by educational institutions in courses both for geotechnical engineers and geologists.

Autorenporträt

Anna Bondo Medhus holds a Ph.D. in seismology from the Department of GeoScience, Aarhus University, 2010. In her current position at Energinet, Anna works with pre-investigations related to energy transmission projects and renewable energy. Anna was a researcher and research program manager at VIA University College (2018-2022) in the Center of Applied Research and Development in Building, Energy and Environment (Horsens, Denmark). She managed research projects mainly related to pre-investigation for urban development projects and in collaboration with several partners like consultancy companies, and utilities. She developed and taught a course in geophysics for engineering students, which provided insight on the needs of engineers and how to teach students from other professions. From 2010 to 2018 Anna was employed in COWI as a specialist in applied geophysics working with site investigations for various construction and foundation projects in nationwide and international project groups. She was leading work on optimizing data access and data management throughout COWIs geoscience, groundwater, and geotechnical groups. Anna has always had a focus on the dissemination of knowledge with a keen eye for the interest, needs and starting point of the audience. Her art is to make difficult topics easily understandable without compromising on facts. Lone Klinkby holds a PhD in deep reflection seismics from the Department of Earth Sciences at the University of Aarhus, 1998. Currently Lone works in COWI as Project Director and Business Development Director within Energy and Geoscience. From 2008-2011 she worked within Research and Development at Vattenfall with a focus on deep CO¿storage demonstrations projects in Denmark and Germany. Further, she participated in international scientist projects and networks on CO¿storage guidance and monitoring. Former positions include research on reservoir geophysical data at the Geological Survey of Denmark and Greenland (1998-2005). COWI is an international consulting group within the engineering disciplines of energy, buildings, infrastructure, and environment. Lone is part of a group of geophysicists and geologists working across departments in close connection with COWIs geotechnical groups. Since 2011 she has worked with applied geophysics for projects related to deep and shallow foundations both on- and offshore. She is an active participant in international project groups and her work includes leading combined projects on pre-investigations and for establishing decision foundations for the transition toward renewable energy. Lone work in the interface between professions and strive for increasing interpersonal understanding for the benefit of the projects.
