Note:

The velocity head has changed by more thano.Sft (0 15111). This may indicate the lIeed for
additiollaltrosssections.
The cOllveyance ratio (upstream conveyance divided by downstream conveyance) is less than
0.7 orgreac..r than 1.4. This may indicate the need foradditionll.l crOH sections.
The energ~ 10ss waS greater than 1.0. ft (0.3 Ill). between the current ~nd previous ,ross section.
This may lndicau 1:he need for additlollal cross sections.
Multiple critical dep1:hs were found at this 10clI.1:ion. The critical d..pth with the lowest. va1id,
