CV2015 Hydraulics

[Lecture: 26 hrs ; Tutorial: 13 hrs; Lab: 0 hr; Pre-requisite: CV1012; Academic Unit: 3]

Learning Objective :

To introduce the basic principles of the hydraulics of open channel flows, which are essential fundamentals for the design of water resources related projects.

Course Content :

Concept of boundary layer: surface roughness, velocity distribution in turbulent flow, law of the wall. Open channel hydraulics: uniform flow, critical flow, application of energy and momentum principles, hydraulic jumps, gradually varied flows, backwater computation.

Course Outline :




Concept of boundary layer: velocity distribution in turbulent flow


Steady uniform flow: resistance to flow; Chezy and Manning's equations. Most efficient channel cross-section.


Specific energy diagram; critical flow condition. Froude number. Channel transitions and controls: humps and contractions, weirs, sluice gates


Steady non-uniform flow: characteristics and classification of gradually varied flow profiles, control sections.


Computation of water surface profiles; The Direct Step method.


Momentum equation and hydraulic jump.

Learning Outcome :

After successful completion of the course, the students should be capable of understanding the fundamental knowledge of open channel hydraulics and applying them to solve practical engineering problems relating to the planning and design of water resources projects.
