SPRING 2013
HOMEWORK No. 09:  CULVERT HYDRAULICS

  1. Design a circular concrete culvert with the following data:

    Q = 500 cfs;

    Inlet invert elevation z1 = 100 ft;

    Tailwater depth y2 = 4 ft;

    Barrel slope So = 0.01;

    Barrel length L = 200 ft;

    Manning's n = 0.013;

    Roadway shoulder elevation Er = 115 ft;

    Upstream freeboard Fb = 2 ft;

    The entrance type is square edge with headwalls.

    Use ONLINECHANNEL 06 to calculate normal depth and ONLINECHANNEL 07 to calculate critical depth in the culvert.
