Example # $3$: calculate the follewing parameters

for the bed level raise.

$q=3m$

a$)$ Determine the specific energy at section $2(E_2)$

b$)$ Determine the dewnstream depth $(y_2)$

c$)$ Determine the absolute change in the water

surface level $(y),y_1=z+y_2+y$

d$)$ Determine the downstream Froude number $(F_2)$

e$)$ Draw the E$-$y curve and interprete the

results.
