Description: GSF ABSTRACT This dataset comprises high-resolution multibeam echosounder (MBES) bathymetry and backscatter data collected in a 7.5 km segment of the River Rhine (km 747.0–754.5, Düsseldorf, Germany) between July 24th and 31st, 2024. The survey, conducted with a Kongsberg EM2040P MKII multibeam echosounder operated at a frequency of 300 kHz, achieved a point density of ≥ 160 points/m² and met the IHO Special Order standards (horizontal uncertainty ≤ 15 cm, vertical uncertainty ≤ 3 cm). Furthermore, the dataset includes 8,654 manually annotated quartzite blocks (mean area: 1.90 m², mean height above riverbed: 0.28 m), which were used to train a U-Net convolutional neural network (CNN) for an automated detection. The dataset comprises the raw (.db) bathymetric data, the applied sound velocity profiles (.csv), the pre-processed and filtered bathymetric data (0.25 m grid as .xyz and .tif) with their uncertainty metrics (.xyz, .tif), the computed and cleaned backscatter mosaics (available as 0.20 m and 0.25 m pixel size mosaics in .xyz and .tif format) and the manually digitized polygon annotations (.shp). The data are suited for hazard mapping, geomorphological studies, AI/ML model training (e.g., semantic segmentation) as well as the validation of automated boulder detection methods.
