Shkw a complete solution and final answer. There are $2$ rivers at $10$ meters apart that run down to the sea from the watershed reservoir both have equal base of $2$ meters both have a slope of $0\mathrm{.}003$ and both have an n$=0\mathrm{.}015.$

River has a trapezoidal cross section with side slopes of $1\mathrm{.}0$ horizontal and $1\mathrm{.}5$ meter vertical. River B has a rectangular cross section with the best hydraulic section

Compute the following:

a$.$ The discharge flow Q of River A

b$.$ The discharge flow Q of River B

c$.$ Compute the difference of the flow charges
