Hydroacoustic monitoring has become an effective tool for riverbed mapping, underwater object detection, and environmental assessment, particularly in areas affected by intensive anthropogenic impact. The methodology was validated using hydroacoustic survey data acquired in March 2025 within a section of the Dnipro River near Zaporizhzhia. This study presents an integrated approach combining Side Scan Sonar (SSS), echo sounding, DownScan imaging, and GIS technologies for underwater object monitoring in a section of the Dnipro River near Zaporizhzhia. The proposed workflow enables the generation of bathymetric and composite maps, spatial interpretation of acoustic anomalies, and assessment of environmental and technogenic risks. The results indicate that the detected anomalies are predominantly of natural origin, while no explosive hazards or submerged anthropogenic objects were identified within the surveyed area.
