Torne River, Sweden and Finland
The Torne Rivers survey is part of the EU Horizon project UAWOS. All datasets belonging to the UAWOS project can be accessed here. The Torne River flows along the border between Sweden and Finland from North to South and drains into the Gulf of Bothnia. The UAWOS focus area on the Torne was the river reach between Pello and Övertorneå and the survey was carried out from September 3rd to 9th, 2024.
The survey primarily aimed to measure WSE, river depth, and river surface velocity based on UAS hydrometry payloads. Throughout the survey, multiple payloads were utilized to separately collect water surface elevation (Geolux LX-80 Altimetry Radar), cross-sectional bathymetry (ZondAeroLF Water Penetrating Radar), and the water surface velocity (RSS 300 Doppler Radar). Data is shared at three processing levels: The raw data (Level 1), processed point data (Level 2), and point data referenced to a reference river centerline/reference cross section lines (Level 3). Specialized software is required to process most Level 1 data, while Level 2/3 data comes in standard comma-separated ASCII files. More details about the different datasets and processing levels are included in the dataset readme file and the readme files belonging to the individual datasets.
