| Main themes |
- Theory of open channel hydraulics
- Classification of flow : uniform and non-uniform flow ; steady state and gradually varied flow
- Properties of open channels : energy and momentum principles
- Velocity profiles. Specific energy, specific force
- Hydrometrology : Venturi, Parshall, gauging,
- Uniform flow theory
- Gradually varied flow theory. Classification of hydraulic axes. Integration methods
- Rapidly varied flow : hydraulic jump, fall, weirs
- Types of irrigation systems : gravity, pressure or drip irrigation
- Theory of water flow in pipes
- Pressure irrigation networks : pumps, pipes, sprinklers; design of a network
- Irrigation and salinity.
|
| Aims |
Upon completion of the course and practicals, the student will be able to :
- to characterize different flow regimes in open channels ;
- to apply the principle of energy conservation and momentum on flow in open channels ;
- to characterize a velocity profile in an open channel;
- to understand the functioning of discharge measurements;
- to understand theory of uniform flow, gradually varying flow and rapid varying flow;
- master the theory of flow in pipes;
- describe the principles that underlie the various irrigation techniques;
- be able to design an irrigation management scheme and to evaluate its functioning;
- master the theoretical concepts that underlie water flow towards subsurface drains and the design techniques for drainage networks;
|
| Content |
A general introduction to open-channel hydraulics and fluid flow in pipes will be given. We will then address the plant needs for irrigation. A brief description of the various irrigation techniques will follow. The course will focus on the different components of irrigation networks (water uptake, water transport sprinklers/drippers,
). The practicals will be used to perform experiments on the laboratory experimental channel, some field tests on irrigation and uniformity and to design an irrigation network.
|
| Other information |
Evaluation The students will be evaluated on the basis of their reports on the practicals as well as through a final exam. The final exam will be oral with a written preparation, and will include problem solving as well as comprehension questions.
