Abstract

Disasters caused losses and damage to the coastal areas of Pariaman City. The construction costs for development in coastal areas are relatively expensive. Early good research must be done to monitor shoreline changes and reduce losses and damage in the coastal areas of Pariaman City. The method used to monitor shoreline changes using satellite images with GIS techniques. The coastal change analyzes is studied including coastal erosion and sedimentation. In this study, disaster mitigation and impacts reduction caused by coastal changes are the final purposes. The losses and damage due to coastal changes were monitored during a certain time. The results of this study are aimed to make a solution for disaster mitigation in coastal areas caused by the shoreline changes in Pariaman City.

Summary

Introducing

Et al (2007) [1] study on Tottori Beach, Japan which has a coastline of 129 km. The study was conducted to reduce/control coastal erosion and sedimentation that occurred on the coast of Tottori, Japan. This study analyzes the causes and effects of coastal erosion that occurred on the Unawatuna coast. The method carried out by calculating the amount of erosion that occurred on the shore of Shandong and its causes, calculated the sediment load from the main rivers in Shandong and the coastal protection that had been carried out along the shore of Shandong. The method is carried out by analyzing the causes and measures of protection against erosion and shoreline management. This study uses the sand nourishment impact model (N-tool) method for protection against erosion and sea-level rise. It was found that sand nourishment was an effective flood protection method for the Dutch coast. Based on laboratory tests that the grading of sand sediment has the same grain grading as sand 35 years ago
