Hydraulics I is an introductory course that applies basic principles of fluid mechanics to practical problems in hydraulics. It set the basis for subsequent courses related to the design and management of Hydraulic Works, or issues of flood risk.

By the end of the course, the student has the necessary knowledge and skills to:

• Identify fundamental open channel problems in practical engineering and determine appropriate approaches.
• Calculate downstream flow height and energy for flood risk mitigation.
• Describe physical phenomena with respect to forces/pressures of open chanel flow, both qualitative and quantitative.
• Estimate flow depth and flow velocity in open channels.
• Practice in the design of hydraulic works.

• Decision making
• Autonomous work
• Project design and management

1. Introduction to hydraulics. Control cross sections, Velocity distribution in open channels
2. Open channel flow equations (Continuity, Momentum, Bernoulli)
3. Energy, total energy, specific energy
4. Uniform flow, manning equation, steady flow in flood plain
5. Optimal cross section
6. Non uniform flow, flow classification
7. Hydraulic jump - stilling basins
8. Specific energy – critical depth
9. Non-uniform flow – Gradually varying flow
10. Flow profile classification
11. River flow, control, and measurement of open channel flow
12. Control cross sections
13. Spillways, weirs

Assessment Method

I. Final restricted exams (80%) of 6-9 problems including:
- Derivation of fundamental hydraulic equations
- Open ending questions
- Problem solving (math)
- Images from the syllabus videos (available in the e-class), for which students are asked to explain what will follow and why after a given event

II.Project (20%).
