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.
Teaching methods
Lectures, practical exercises, homeworks 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 softwares and creation of Excel calculation sheets

Evaluation methods
The final mark for the course comprises the continuous evaluation (40%) and the oral examination during the exam session (60%).
Continuous evaluation:
Continuous evaluation:
- Two homeworks evaluated based on a report
- One written test about open-channel flow calculations
Oral exam:
- Preparation of answers on the blackboard, without the lecture notes
- Three questions covering the whole course
