Using Spatial Images to Detect Changes in Shorelines

The purpose of this study is to investigate the shoreline response toward the installed submerged breakwater and assess the performance of the breakwater with the shoreline response at the site. The coastal region has become one of the focus and choice to the society due to the aesthetic view and economic global especially fishing activities. Many activities such as manufacturing by the local and international, ports, tourism industries have been blooming in coastal cities. However massive activities such resort development, extreme water sports, and ports activity have caused the some problem and instability to the dynamic of the beach. In results of the activities, beach either erosion or accretion over the past years and calling for measures to protect this valuable asset from disappearing. Submerged breakwaters (SBWs) has been chosen for this studies and are becoming a popular structure protection and one of the options for coastal protection, mainly due to their low aesthetic impact on the natural environment area and marine habits. However, the effectiveness of the SBWs has rarely studied over the past years, and therefore the efficiency of the structure remains unknown. The main objective of this investigate the structural and environmental condition that govern the mode of shoreline response using satellite image and geoprocessing tools in the response (shoreline erosion vs shoreline accretion) to SWBs. The result from the studies is to provide a starting point to the future research at the site in estimating the shoreline response to SBWs.
