COASTAL SEDIMENT CELLS FOR THE NORTH COAST OF EAST JAVA, INDONESIA

Sediment cells are spatially discrete areas of the coast within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange, often described using sediment budgets or net sediment transport. They include areas of sediment supply (sources), sediment loss (sinks), and the sediment transport processes linking them. The objective of this study is to present a method to determinate coastal cells that was applied in the north coast of the East Java Island, Indonesia. This work is based on secondary data, various satellite image data and fields survey. The coastal cell boundaries were classified into three type; namely, static, dynamic, and convergent. Twelve sediment cells were identified in the north coast of the East Java. Also, in certain parts of the northern coast of East java can be found sub cell boundaries. These coastal cells help in a more planned approach to coastal planning and management in Indonesia.
