Goal(s)
The presence of a free surface in certain flows is a source of complexity.
The objectives are that the students should be able to:
- determine the water depth in an open channel for a given flow rate
- draw and compute the shape of the free surface for gradually changing geometries
- qualitatively predict the shapes of the free surface for flows within channel geometries that are rapidly varied (singularities).
Content(s)
Basic concepts in open channel flows: the Froude number, critical depth, the hydraulic jump.
The uniform flow: velocity vertical profile, flow resistance, Chézy equation, normal depth
Nonuniform flow in gradually varying channel sections: water depth computation in non uniform flows, channel controls.
Channel transitions: bottom step, channel contraction,
specific energy Hs, Hs-h diagram
