DESCRIPTION - summary of the module content
AIMS - intentions of the module
To introduce the basic concepts of engineering geology, site investigation procedures, and the principles of geotechnical engineering with some applications in civil engineering.
INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)
Note: List A comprises core outcomes that will be covered fully in lectures and must be achieved by all students to meet the minimum university requirement for progression. List B comprises outcomes that are EITHER more difficult to achieve OR are to be achieved by private study (or both). All outcomes will be assessed, and coverage of List B outcomes is essential for both BEng and MEng students.
