Page 65 - Energy = —-{-« *g where V is the mean velocity, g is the acceleration due to gravity, and d is the depth of water. When the velocity of the water approaches the velocity of the elementary wave, the total energy of flow becomes unstable and variations in the profile of the free water surface will result. If the change in velocity is rapid a standing wave will form. 4 6 8 10 12 14 16 Specific En«rg...
