Course outline
01
Fundamentals
Free-surface versus pressurised flow, classification of regimes, review of Bernoulli and momentum.
02Flow regime
Gravity waves, Froude number, critical depth and control sections, subcritical and supercritical regimes.
03Uniform flow
Chézy and Manning-Strickler, normal depth, channel design and the most efficient section.
04Channel geometry
Flow area, wetted perimeter, hydraulic radius and the usual sections: rectangular, trapezoidal, circular.
05Hydraulic jump
Specific force, Bélanger equation, energy loss and stilling basins.
06Gradually varied flow
The backwater equation, M, S, C, H and A profiles, and numerical integration methods.
07Hydraulic structures
Weirs and sills, sluice gates, free overfalls, bottom steps and Venturi flumes.
TDProblem sets
Three worked problem sets, from channel sizing to the design of a stilling basin.
