[Acoustics] Depth Sounder usage in WinRiver

[McBride, Daniel J MVR]

I was wondering how many of you use external depth sounders when collecting
ADCP data with WinRiver.  For those of you who do, I have a couple questions:

1) Have you compared the [ADCP] calculated depths to the external DS depths,
and how much do they differ?
2) Does it affect the discharge calculated by WinRiver, and how much?
3) Under what kind of conditions have you done this?
4) Do you think you get more accurate discharge numbers by using an external
DS?

I tend to think that anytime you can get more accurate values for the various
parameters that you're measuring, it will only make your measurement that
much more accurate.  I'd like to see if that's what people are finding with
their data.

Thanks for any input!
