The Evaluation of the Physical Condition in Coastal Area as a Result of Changes of Suspended Sediment (Case Study: Coastal Area of Surabaya and Gresik)

Abstract

Indonesia as an archipelagic country, should have an advantage in the maritime sector. One important part of a country's maritime systems is a port. Coastal area is a transitional region and interaction between terrestrial and marine ecosystems. Coastal is affected by waves of sea water. The coast is also a zone that is the place of deposition of seawater erosion. The increase of coastal activities has an impact on changes in physical conditions, especially on changes in coastline and suspended sediment levels which are increased. Remote sensing methods with satellite imagery can be a solution for changes of monitoring coastline suspended sediment levels that occur along the coastal area. In this study, monitoring of changes in coastal conditions over a period of 15 years (2002-2017) had been carried out. The method used in this study uses remote sensing technology, namely the use of land and ocean separation algorithm and Total Suspended Sediment (TSS) algorithm methods.
