Brief Handbook Description: The objectives of this unit are to demonstrate how the granular structure of soil materials controls their engineering behaviour; translate particle micromechanics to improve macroscopic engineering predictions; and establish the intimate connection of geotechnical engineering to other disciplines where granular materials play a pivotal role, including mining engineering, bulk materials handling, and geophysics. Similarly, this course will cohesively connect geotechnical engineering with fluids engineering principles, as well as enhance students' background in materials science. At the end of this unit students will be able to understand and use Discrete Element Method to evaluate and solve geotechnical problems such as rockfall interactions with surrounding terrain. They will also critically analyse pile penetration and silo discharge in light of granular mechanisms; apply soil rheology to carry out parametric study of landslide flows; and understand and use dimensionless analysis principles to predict resistive forces on obstacles. Strong focus will be dedicated for communicating students' results using written methods appropriate for professional engineers.
Assumed Knowledge: None.
Lecturer/s: Dr Einav, Itai
Tutor/s: Ebrahim Alaei; Matt Macaulay
Timetable: CIVL5460 Timetable
T&L Activities: Tutorials start in 2nd week of the semester. Attending the tutorial is compulsory. Students must attend the tutorial where they are specifically listed, unless approved by the coordinator.

Students should be aware that missing more than two tutorials can lead to failing the course, unless their absence is fully justified via the proper special consideration form.
