Course Objective

The aim of this course is to make a general review of and recall most of the materials
of the first course in soil mechanics of undergraduate level. Presenting basic concepts
of permeability and seepage, stress distribution in a soil mass due to various types of
loading conditions, development of pore water pressure due to undrained loading
conditions, and introducing more advanced topics in these subjects.

Learning Outcomes of the Course Unit

1   To be able to recall and examine index properties of soils.
2   To be able to realize and evaluate the effects of water on soil behaviour.
3   To be able to apply advanced solution methods on seepage problems.
4   To be able to evaluate behaviour of soils under loading.
5   To be able to Interpret, report and present solutions of engineering problems.
