Welcome to a fascinating journey into the heart of geotechnical engineering. In "Subsurface Uncertainties in Geotechnical Engineering," we peel back the layers of the Earth to uncover the mysteries lurking beneath the surface. Geotechnical engineers face two primary categories of uncertainty: natural variability and knowledge uncertainty. Natural variability, the inherent randomness in geologic materials, can't be eliminated but can be better understood through data collection. Knowledge uncertainty, on the other hand, stems from a lack of data and understanding of subsurface materials.

In this session, we unravel how geoprofessionals tackle these uncertainties using inductive reasoning, limited data, judgment, and experience. We'll explore the role of subsurface exploration programs in reducing knowledge uncertainties and improving risk assessment. You'll discover why accurate site characterization is key to minimizing subsurface uncertainties and enhancing project safety.

Join us as we delve into the world of geotechnical risks and explore strategies for reducing uncertainty. We'll also evaluate the economics of subsurface exploration programs and how their benefits often outweigh the costs. By the end of this session, you'll have a deeper understanding of how geotechnical engineers navigate the challenges of subsurface uncertainties and ensure the success of their projects.
