Subsurface Geological Investigations for Engineering, Environment and Resources

By the end of this course, you will be able to:

• Visualize and interpret subsurface conditions using geological and geophysical data
• Design and evaluate subsurface investigations for decision-making
• Integrate drill hole data, geophysical surveys, and spatial data into geological models
• Infer strata, structures, and properties while accounting for uncertainty and heterogeneity
• Apply models to risk‑informed decisions for engineering, resources, and the environment 

Description

Subsurface conditions influence the performance and cost of engineering, environmental, and resource projects, yet they are rarely observable and often poorly constrained. As a technical professional, you are often required to make decisions about foundations, underground space, groundwater, and resource potential using incomplete and uncertain geological information.

This course addresses the challenge of clarifying geology from diverse data. You will explore how drill hole data, geophysical surveys, and geological mapping are designed, integrated, and interpreted to support defensible engineering and geoscience decisions. Emphasis is placed on how material properties, heterogeneity, and uncertainty affect risk in subsurface projects.

Through structured approaches, real‑world examples, and applied frameworks, this course equips you with practical skills to build, evaluate, and communicate subsurface geological models that support groundwater modelling, underground construction, resource development, and environmental applications.
