Sediment Transport Direction Derived from Grain-Size Statistics on the Continental Shelf Off Mangalore, West Coast of India

Grain-size statistics are employed in sediment transport studies. The alongshore transport of sediment in shallow regions (30-50m depth) and deeper regions (>l50m depth) is in north and south directions, whereas in the depth range of 50-75m, the sediment transport direction is towards the south. The onshore-offshore sediment transport study reveals that the sediment transport direction is towards onshore where fluvial influence is absent and the direction is towards both onshore and offshore where the fluvial influence is prevalent. The studies further reveal the different energy regimes of transportation.
