ABSTRACT
A 600 kHz acoustic Doppler device was used dur-
ing the field trips for the discharge measurements
(RDInstruments, 2003). The device was coupled to
a navigation GPS and the measurements were mon-
itored on a notebook. The Doppler device was used
through a specially build platform positioned on the
side of a wood boat. The reference used for the mea-
surements was the bottom track mode. No correction
was applied regarding the moving river-bottom. For
each measurement, a minimum of 4 transects were
done for each selected point. The configuration file
used was based on the manufacturer recommenda-
tions, with the exception of the export mode that has
been modified to take into account the device range
depth detection and the cell size.
