Abstract

Understanding sediment transport and submarine canyon dynamics is essential for comprehending the complex processes occurring on the ocean floor. This paper aims to investigate the mechanisms of sediment transport and the dynamic behavior of submarine canyons. Sediment transport plays a significant role in shaping the morphology of the ocean floor and influencing the distribution of sedimentary environments. Various factors, including current patterns, wave action, and gravity flows, contribute to sediment movement and deposition. The study examines the processes of erosion, transport, and deposition of sediments within submarine canyons, which are key features of the underwater landscape. The interaction between turbidity currents, gravity flows, and the canyon morphology is explored, highlighting the impact on sediment transport and canyon evolution. Additionally, the paper discusses the influence of external factors such as climate change and anthropogenic activities on sediment dynamics and submarine canyon systems. The findings emphasize the importance of interdisciplinary approaches, integrating geophysical surveys, sedimentological analyses, and numerical modeling, to gain insights into sediment transport and submarine canyon dynamics. This knowledge can contribute to improved understanding of ocean floor processes and inform effective management strategies for coastal and offshore environments.
