i'm not getting the solution to the water resources 6-min problem # 34. it seems pretty straightforward, but they're using some odd version of the manning equation that i've never seen. if you solve the problem using the standard
Q = (1.00/n)AR^(2/3)sqrt(S),
you get about 29.3 m^3/s. but they have some equation
Q = ((1/n)A^(5/3)sqrt(S))/P^(2/3)
and they're getting an answer of 9.3. any input on this? why arent they using the standard manning equation?
