The study of loaded and free surface flows represents the vast majority of problems. of hydraulic engineering. This module presents the basic concepts of unidirectional flow. (wired approach) in steady state or transient mode. The use of calculation codes allows a more realistic approach to industrial situations and river flows.


Flow under load :
To present the basics of hydraulics applied to pipe flows under load and calculations. of pressurized networks.

Free surface flow :
To train engineers capable of tackling problems of river hydraulics, networks irrigation, sewerage networks, ...


Definition of the load flow. Bernoulli's theorem. Concepts of linear and horizontal pressure losses singular. Classical formulas for calculating pressure losses. Pipe networks.Use of a calculation code for pipe flows (EPANET software).


Characteristics of free surface flows: velocity profiles, bottom friction, coefficient of Strickler. Uniform flows, definitions: reference heights (normal and critical), number of Froude, regimes (fluvial or torrential). Varied permanent flows (eddies, jumps), applications through examples: modeling of a natural flow, wedging of a water line based on concrete cases. Operation and dimensioning of hydraulic works. Presentation of
Non-permanent flows (Saint Venant equation, flood models).
