(50 percent) Using DIRECTSTEP in http://onlinecomp.sdsu.edu,
calculate the water surface profile for the case of a steep channel flowing into a milder
steep channel (S3 curve), with steep slope So= 0.02, and milder steep slope So= 0.006,
with the following conditions: Q = 5 m3/s; b = 2 m; z = 1; and n = 0.015.
Use CHANNEL
in http://onlinecomp.sdsu.edu to calculate the upstream and downstream normal flow depths.
Report the normal depths and the total S3 curve channel length (to within 1 mm below normal depth) in m.
