Depth Averaged Streamflow Velocity Data for the São Francisco River near Torrinha, Bahia, Brazil, 2014
Hydrographic survey data were collected from May 22 through June 10, 2015,
using an acoustic Doppler current profiler (ADCP) coupled with an RTK-GNSS
rover. The collected hydrographic data consisted of three elements—riverbed
elevations derived from bathymetry, depth-averaged streamflow velocity, and
instantaneous discharge measurements. Hydrographic data were collected
as the boat moved across the river at planned cross sections distributed
throughout the reach. Data collection software integrated and stored the
depth and velocity data from the ADCP and the horizontal and vertical
positioning data from the GNSS data in real time. Data processing required
computer software to extract bathymetry and velocity data from the raw ADCP
and GNSS files and to summarize and map the information. Streamflow was
measured to document the streamflow of the river at the time of the survey, and
the variation of streamflow around Grande do Pecado Island.
