Bathymetry plays a crucial role in coastal management. Monitoring bathymetric changes is essential for understanding coastal erosion and managing marine resources effectively. Bathymetric information is critical for coastal erosion studies, as it helps in understanding sediment transport and the effects of wave dynamics on coastal structures. Recent studies have demonstrated that employing camera systems can effectively capture bathymetric data through innovative techniques. One of these tools is UBathy which is designed to derive bathymetric data from video footage. This paper is using camera data and UBathy tool to extract bathymetric data at My Khe Beach, Da Nang city, Vietnam. The algorithm employed by UBathy integrates various advanced techniques, including the Kalman filter and dynamic mode decomposition (DMD) to enhance the accuracy and effectiveness of bathymetric estimations from video sources. The result compared to surveyed data in March 2024, which is measured by multi–beam echo sounder Odom Echotrac MKIII device. The result reveals that bathymetric data ranged from -2.43m to nearly 0.1m. The accuracy of this method allows for real time monitoring and assessment of coastal bathymetry, which is crucial for understanding wave dynamics, sediment transport and coastal morphology changes over time.
