SEDIMENT TRANSPORT ALONG THE GOA NORTH KARNATAKA COAST, WESTERN INDIA

Landsat images, aerial photographs, and topographic maps of the coast of Goa and of north Karnataka were interpreted to delineate sediment-transport sectors. Thirty six sediment-transport sectors were identified from landform indicators and patterns of sediment transport. Although sediment-transport direction is bi-directional, net major sediment transport is southward. The geomorphic study identified possible sediment sources and sinks. Contributions of sources and losses due to sinks are assessed qualitatively as significant, moderate, marginal or unknown. The sediment balance is positive overall, and is reflected in large spits in the southern part of the study area.
