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: The energy loss was greater than 1.0 ft (0.3 rn). 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.
Location: River: minnesota Reach: 1 RS: 4800.5" Profile: PF 1
Waming: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for
additional cross sections.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less than 0.7
or greater than 1.4. This may indicate the need for additional cross sections.
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.
Location: River: minnesota Reach: 1 RS: 4618 Profile: PF 1
Warning: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for
additional cross sections.
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.
Location: River: minnesota Reach: 1 RS: 4433." Profile: PF 1
Warning: The energy equation could not be balanced within the specified number of iterations. The program
selected the water surface that had the least amount of error between computed and assumed
values,
Waming: 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,
