Specific learning outcomes of the course
- 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
Due to the COVID-19 crisis, the information in this section is particularly likely to change.Lectures, practical exercises and laboratory, all in close link with each other. Depending on the number of registered students, courses will be given in the class or online.
Numerous examples of applications and real cases where the methods developed in the course were applied
Use of didactic softwares, videos and a MOOC course, creation of Excel calculation sheets
Due to the COVID-19 crisis, the information in this section is particularly likely to change.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, with 3 questions covering the entire course.
In case of severe failure of one part of the exam (mar < 7/20), the above-mentioned weights might be adapted.
MOOC edX « Hydraulique fluviale 1 : écoulements à surface libre »
Lencastre, "Hydraulique générale".
Written exam: exercises to be submitted as a take-home exam with limited time.
Oral exam: online discussion based on the lecture slides, without preparation time.
