Target class: headstream Context triple: [White Main, instanceOf, headstream]
-
A.
headworks
Headworks are the structures and facilities at the intake of a water conveyance or treatment system that control, measure, and initially condition the incoming flow.
-
B.
headwaters section
The headwaters section is the uppermost part of a river system where small streams and springs originate, characterized by steep gradients, fast-flowing water, and relatively pristine conditions.
-
C.
ephemeral stream
An ephemeral stream is a temporary watercourse that flows only briefly in direct response to precipitation, remaining dry for the rest of the year.
-
D.
feeder stream
A feeder stream is a smaller watercourse that flows into and supplies water to a larger stream, river, or lake.
-
E.
headwater stream
chosen
A headwater stream is a small, often narrow and shallow watercourse at the uppermost reaches of a watershed where surface runoff, springs, or snowmelt first converge to form the initial flow of a river system.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
