Teaching methods

Class hours consist of regular lectures and teaching assistant hours, with illustrations of numerical applications.

Assessment methods

A written test must be passed, either during the semester or later during the year. The student can opt to improve his final mark by passing an additional oral examination.  

The "Hydraulics" module is part I of a 2-module course, "Hydraulics and Design of Urban Hydraulic Structures". The student performance is evaluated at the end of the two modules.
