ADCP and topographic measurements (C3) in the framework of the DANUBIUS Implementation Phase Project - DANUBIUS-IP – Support Project – Contract No. 116PHE/2025

ADCP and topographic measurements in the framework of the DANUBIUS Implementation Phase Project - DANUBIUS-IP – Support Project – Contract No. 116PHE/2025 (PN-IV-P8-8.1-PRE-HE-ORG-2025-0279) – September 2025 – St. George and Sulina mouth. The hydrodynamic datasets were acquired with a powered boat-mounted acoustic Doppler current profiler (ADCP, RiverRay 600 kHz, manufactured by Teledyne Marine) Data collection and processing Software: WinRiver II, Version 2.23.00.01 The Discharge summary files and bathymetry were exported for each cross-section using the equipment software. The topographic datasets were acquired with Trimble R580 GNSS System. The determination of the coordinates (X, Y) and elevations (Z) was done in the Stereographic projection system 1970 (the official Projection System in Romania) with the ETRS 89 datum, and the reference elevation is the Black Sea - Constanța 1975 (the official Altimetric System in Romania).
