Flume Template



The limit of FLUME is the extent of the structure.


Data Extraction

Capture Conditions


If FLUME is ≥ 0.12" along the longest axis,

Then capture.


Source Interpretation Guidelines




If FLUME meets capture conditions and carries CANAL/DITCH that meets

capture conditions, then capture FLUME, CANAL/DITCH, and



If a flume does not meet capture conditions and carries CANAL/DITCH,

Then capture CANAL/DITCH and, if required, capture UNDERPASS to allow definition of the relationship between CANAL/DITCH and the feature over which it passes.




If a section of CANAL/DITCH is labeled "AQUEDUCT" where it passes over

another feature, then capture that section as CANAL/DITCH, and BRIDGE

or FLUME, if capture conditions are met.
