Ogee Fall: ● In this type of fall, an ogee curve (a combination of convex curve and concave curve) is provided for carrying the canal water from higher level to lower level. ● This fall is recommended when the natural ground surface suddenly changes to a steeper slope along the alignment of the canal. ● There is a heavy drawdown on the u/s side resulting in lower depth, higher velocities and consequent bed erosion. ● Kinetic energy is not well dissipated due to smooth transition.
