It was only a matter of curiosity as to whether there might be a
suitable descriptive term. A single word, if meaningful, helps condense the
descriptive text - which is why there are a lot of terms out there for that
purpose. But in this case there appears to be no suitable term that would
be widely understood. Open culvert is certainly applicable, but probably
not clear enough in the particular application concerned.
