Warning: During subcritical analysis, the water surface upstream of culvert went to critical depth.
Note: The normal depth exceeds the height of the culvert. The program assumes that the normal
depth is equal to the height of the culvert.
Note: Culvert critical depth exceeds the height of the culvert.
Note: During the supercritical calculations a hydraulic jump occurred inside of the culvert.
Note: The culvert inlet is submerged and the culvert flows full over part or all of its length. Therefore,
the culvert inlet equations are not valid and the supercritical result has been discarded. The
outlet answer will be used.

ERRORS WARNINGS AND NOTES
Errors Warnings and Notes for Plan : Rancho
River: Rancho Drive Reach: Firestone RS: 9376 Profile: 100-yr
Warning:The energy equation could not be balanced within the specified number of iterations. The program used critical depth
for the water surface and continued on with the calculations.
Warning:Divided flow computed for this cross-section.
Warning:The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate
the need for additional cross sections.
Warning:During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The
program defaulted to critical depth.
River: Rancho Drive Reach: Firestone RS: 9324 Profile: 100-yr
Warning:The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for additional cross sections.
