If the river depth is larger than the subcritical sequent depth, a submerged hydraulic jump forms. Sometimes, concrete blocks called "baffle blocks" are placed on the stilling basin floor to help th
If the free surface at a distance from the axis of the vortex, which is sufficient for its effect to be negligible, is 180 mm above datum, what will be the height above datum of a point B on the fre
Assuming the following equation represents the true distribution in the vertical, determine the actual distance below the surface at which the velocity, u, equals the depth-averaged velocity, U.
Some distance downstream, the velocity profile can be (very) roughly approximated by a region inside the wake with u = U/2 and an exterior region with u = 3U/2.
