The file Discharge_Data.xls contains river discharge measurements by ADCP, BD,
GPR with Radar, and PriceAA meter.

In the section BoogieDopp measurement Notes:

The 4th column is the uncorrected BD discharge value.  This is usually the
value from the iPac (Nortek) software.  In some cases the software applied
an 8.4% correction which was the correction value suggested by Nortek.  The
needed correction value determined (in tow tank) for this instrument configuration was
found to be 10.6.  The three columns are shown for reference.  The Q in 
column 8 is a manual calculation based on mean velocity profile and area to
check instrument software calculations.
