CIV E 530 - OPEN-CHANNEL HYDRAULICS
FALL 2012
LAB No. 12:   HEC-RAS EXAMPLE


  • Existing Plan

    Run the example in Chapter 4  of the HEC-RAS User's Manual.

    Report the water surface profiles for all three reaches (Fall River Upper, Fall River Lower, and Butte Creek tributary).

    Report the rating curves at the Fall River upstream boundary (R. M. 10), Fall River downstream boundary (R.M. 9.5), and Butte Creek upstream boundary (R. M. 0.2).

    Report the profile output table for all three reaches and all three frequencies (10-yr, 50-yr and 100-yr).

  • Modified Plan

    Change the 100-yr frequency discharge in the Fall River, Lower Reach, River Mile 9.6 to 12,000 cfs.

    Report the profile output table for all three reaches and all three frequencies. Compare with results of A.

    What can you conclude from this exercise?
