So it is obvious that I'm looking for general descriptions or examples of
solving the general physical, fluid-mechanical or mathematical problem.

Let us assume hydraulic engineering of small, large and the largest existing
water falls on earth:
- a volumetric flow rate of 500 kg water per second and more up to much much
more (e. g. 10.000 m3/s),
- a height of fall of 0,5 meters and more up to much much more (e. g. 1.200
meters),
- rigid walls
and
- rigid ground.

IMHO it should be p = cx. 1/2 . ro. v^2 = cx . ro. g . h

where cx is constant near 1,
similar to aerodynamic coefficient
ro is density
V is speed
g is gravitational acceleration
H is waterfall height.
