ADCP and topographic measurements (C2) in the framework of the DANUBIUS Implementation Phase Project - DANUBIUS-IP – Support Project – Contract No. 116PHE/2025

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).本流体动力学数据集由搭载于动力艇的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP，型号RiverRay 600 kHz，Teledyne Marine制造）采集得到。 数据采集与处理软件为WinRiver II，版本号2.23.00.01。 通过配套设备软件，可针对每个测流断面导出流量汇总文件与水深地形数据。 本地形数据集采用Trimble R580全球导航卫星系统（GNSS）采集获取。 坐标（X、Y）与高程（Z）的解算采用罗马尼亚官方推行的1970年立体投影坐标系，大地基准为ETRS 89；高程参考基准为罗马尼亚官方采用的黑海-康斯坦察1975高程基准系统。
