Isar River, Germany - 2025

The Isar River survey is part of the EU Horizon project UAWOS. All datasets belonging to the UAWOS project can be accessed here.The survey's primary purpose was to measure WSE, river depth, and river surface velocity based on UAS hydrometry payloads and transferring previously developed drone-borne measurement techniques to extreme hydrological conditions, i.e. flood events. 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 two processing levels: The raw data, processed point data referenced to a reference river centerline/reference cross section lines. Specialized software is required to process most raw data, while processed 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.
