Unraveling sediment transport dynamics: insights for coastal and port management

Sedimentation poses a persistent challenge to coastal and port operations, affecting navigational safety, operational efficiency and environmental sustainability. This case study investigates the sediment distribution via Multibeam Echo Sounder (MBES) technology for precise and detailed data acquisition at Westports Malaysia for a six month duration after the post-dredging activities. The study specifically focuses on sediment volume and spatial distribution to determine movement patterns and accumulation dynamics within the post-dredging context. By leveraging the MBES technology, high-resolution bathymetric depth and backscatter data are collected, yielding critical insights into sediment dynamics. Key challenges in sediment monitoring, including environmental factors and data processing are addressed, demonstrating MBES as a reliable equipment in hydrographic surveying. The findings help to optimize maintenance dredging strategies, enhancing resource allocation and refining sediment monitoring practices. Furthermore, the innovative application of MBES technology highlights its potential to inform decision-making in sustainable port management. This study not only enriches our understanding of sediment composition and behaviour, but it also advocates environmentally responsible practices in maritime operations. By promoting operational efficiency, minimizing environmental impacts, and supporting the long-term development of port infrastructure, this research demonstrates the integration of cutting-edge technology with targeted analytical approaches in addressing sedimentation challenges across the coastal and port regions.
