The fall which is used to minimise the disturbance and water impact at the fall is -
Ogee falls
Therefore, the Ogee fall is particularly effective in minimizing the disturbance and water impact at the location of the fall, making it a preferred choice in many modern canal systems where smooth flow and structural integrity are critical. While Ogee falls are excellent for minimizing impact, other factors like cost, available space, and the magnitude of the head drop also influence the choice of a canal fall type.
