2. A perennial stream has the following properties: discharge Q = 1000 ft3/s, bottom width b = 150 ft, side slope z = 2, bottom slope So = 0.00038, and Manning's n = 0.035. A 6-ft high diversion dam is planned on the stream to raise the head for an irrigation canal.

 Calculate the normal depth.  Calculate the total length of the M1 water-surface profile. Use n = 400 and m = 400.  Calculate the partial length of the M1 profile, from the dam to a location upstream where the normal depth is exceeded by 1%
