I was reading an article about Design of elevated flumes (flume is a human-made channel for water). Here is a part of the article,

8.1 Data Requirement

Elevations:

  • Top Bank, TB

  • Water Surface, WS

  • Canal Bed, CB

My question is, what does Elevation of Top Bank mean? I looked up at OALD dictionary and I think bank refers to sense 5 "the side of a river, canal, etc. and the land near it". But still not sure about the meaning of the phrase. Does that mean elevation from top of a side of flume to the ground?

    So, flumes are associated with channels or canals, yes. So, bank does mean the sides of a canal or channel. I assume top bank means the distance from the water surface to the top of the bank [of the canal or channel], in which the flume flows. But I am not 100% sure.

    Given the other heights you mention I agree with @Lambie it is almost certainly the very top of the bank of the flume.

  • Agreed with Lambie and mdewey above on what it likely means, but if this is technical jargon, then only an expert can definitively answer this question.
