Hi Aaron,
This one is way outside my field, but was interesting, these questions are
my own curiosity.
Is "low steel" an accepted term in whatever field you are in? I was handing
a hard time finding it used outside "low carbon". Does this term apply to
bridges that aren't made out of steel?
Does this only apply to the intended navigable portion of the waterway? if
yes, how about "instantaneous_navigational_clearance" or
"instantaneous_guide_clearances"?
I found these terms in the USCG Bridge Programs website, without the
"instantaneous" part.
