Channel Description

The channel cross-section at the instrument location is provided below. Datum is taken as the top of the diver access tube (red bar). Width is measured from the left-hand side bank when looking downstream, with locations to left of the diver tube taken as negative and those to the right positive.

Details from an MSc student project are available here. (Note, the information above takes precedence over the student report.)
