Most efficient channel: A channel is said to be efficient if it carries the maximum discharge for the given cross-section which is achieved when the wetted perimeter is kept a minimum.
a) For a triangular channel,
The channel with a side slope of 1:1 is the most efficient channel.
Area of triangle A = 1/2 × y × 2 y
Wetted Perimeter P = 2 √2y
The hydraulic radius for the given section is the ratio of the cross-sectional area to the wetted perimeter of the section.
