Recommended Prerequisites

General Hydraulics I, Solid Mechanics, Engineering Geology.

Teaching Methods

Theoretical classes with detailed presentation, using audiovisual means, of the concepts, principles and fundamental theories and solving of basic practical exercises to illustrate the practical interest of the subject and exemplify its application to real cases.

Theoretical-practical classes where the students, supervised by the staff member, solve practical exercises, which require the combination of different theoretical concepts and promote critical reasoning in the presence of more complex problems.

Laboratory classes with execution/observation of tests, including treatment and interpretation of results.

Learning Outcomes

To provide the students with the main concepts, principles and theories required to explain, understand and predict the physical state and the hydraulic and the mechanic behaviours of soil massifs, in the natural condition and when used as a construction material, under the influence of the loading imposed  by structures built on or inside them.

Work Placement(s)

No
