Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Content
- Introduction : purpose of open-channel hydraulics
- Hydrology: rain, water cycle, measurement and analysis of discharges, rainfall-discharge relationships (unit hydrograph, rational method, Hauff-Vicari)
- Steady open-channel flows: channels, sewers and rivers. Steady uniform flow: Chezy and Manning equations, optimal trapezoidal section, compound and heterogeneous channels, normal depth calculation in channels and sewers. Gradually varied flows: specific energy, critical depth, critical slope, flow profiles (theory and practical calculations). Flow in natural rivers: pseudo-uniform flow. Rapidly varied flow: hydraulic jump, drawn jump. Flow in non-prismatic geometry: flow between a gate and a reservoir, change in bed slope, change in channel width, presence of bridge piers, Venturi flumes, bottom sill, broad crested weir.
- Weirs and spillways: Thin crested weir, normalized Creager profile, free or drawn outflow, spillways
Teaching methods
Lectures, practical exercises and laboratory, all in close link with each other
Numerous examples of applications and real cases where the methods developed in the course were applied
Use of didactic softwares and creation of Excel calculation sheets

Evaluation methods
Exercises (40 % of the final mark): homeworks (hydrology, spillways) and written test consisting in steady flow water profiles calculations using the Excel sheet. The final mark for the exercises is conditioned by the success in the written test.
Oral exam (60 %) on the theoretical aspects (3 questions covering the entire course), with a preparation on the blackboard
