What is the junction discharge (Q at the transition?
The channel at the free fal! has a Station of 10+00 and an Elevation (invert) of 1500.00
a) Calculate the Stations & Elevations for all of the U/S reaches including the transitions.
b) Draw a Plan & Profile view for this channel on an 11"x17" sheet from STA. 10+00 to STA. calcutated in part a, show the bottom & the top of the channel. Show all calculated stations & elevations on the profile view, show the critical and normal depths for each reach, label the latter as the Hydraulic Grade Line abbreviated as H.G.L.
Use a horizontal scale of 1"=500'& a vertical scale of 1"=5'for the profile view & a scale of 1"=5(Xt' in the
teft/right direction & 1"=50' in the up/down direction for the plan view.
c) Show in the profile view a 5' diameter junctioning Reinforced Concrete Pipe (RCP) in the middle of the 2nd
transition from U/S, center the RCp vertically as well.
d) Show the RCP in the plan view as wellwith a 9O'junctioning angle.
e) Determine the type & length of the curve for the varied flow at Reach 3 which terminates at a free fall using the numerical method analysis.
