    dct:description """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.""" ;
