Construct the M-y diagram for the channel section given in Problem 13.1 under a given discharge. Find the critical depth.

Problem 13.1

A hydraulic jump is formed in a trapezoidal channel of 2.0-m bed width, 1: 1 side slope, and carrying a discharge of 6.0 m3 Is. The initial and final depths of the jump are 0.5 m and 2.0 m, respectively. Concrete blocks are placed to stabilize the jump. Calculate the minimum weight of these blocks if the coefficient of friction between the blocks and channel bed,
, is 0.6.
