CIV E 444 - APPLIED HYDRAULICS
SPRING 2016
HOMEWORK No. 11

  1. Design a circular concrete culvert with the following data:   Q = 220 cfs; inlet invert elevation = 100 ft; bottom slope = 0.02; culvert length = 200 ft; tailwater depth above outlet invert = 4 ft; roadway shoulder elevation = 112 ft; Manning's n = 0.013; entrance type is square edge with headwalls, and upstream freeboard = 2 ft. Use ONLINE CULVERT.

  2. Determine the discharge in a gated spillway of length L = 100 ft, when the operating head is 5 ft and the gate opening 1 ft. What is the discharge if the opening is raised by 0.5 ft?

  3. A hydraulic jump is formed in a rectangular channel. The upstream depth and velocity are y1 = 0.1 m and v1 = 3 m/s, respectively. What is the energy loss? Verify with ONLINE CHANNEL 12.

  4. A hydraulic jump is formed in a rectangular channel with q = 0.3 m2/s. The energy loss is 0.145 m. What are the sequent depths? Use ONLINE CHANNEL 16.

  5. A hydraulic jump is formed in a rectangular channel with sequent depths y1 = 0.1 m and y2 = 0.381 m. What is the energy loss? Verify with ONLINE CHANNEL 19.
