Reply To: Extrap

    Replying to add to the above (and to test out posting here!)

    Also note that QRev has an option that allows you to set Extrap analysis to be discharge weighted. This means that each ensemble’s (sample) contribution to the extrapolation evaluation is weighted according to what proportion of the total Q is in that individual ensemble. This solves the problem where ensembles collected close to banks where water might be slow and shallow influence the extrapolation as much as those in the middle that usually contain many times as much flow.

    It also largely eliminates the need to use the sub-sectioning method discussed above, certainly for regular discharge measurements.
