Spatio-Temporal Shorelines Change Model in Totok Bay Southeast Minahasa

Abstract

This study aims to analyze the rate of change in the shoreline and find out the back and forth of the coast in a certain period. Coastal areas play an important role in economic development, namely the transport and tourism industries. Unfortunately, the spatio-temporal variation of the shoreline is very dynamic and is of great concern due to the threat of erosion and accretion. This erosion mechanism is not only the result of natural processes (for example, wind, waves, currents and tides) but also human activity. In this study, the shoreline was considered the boundary between the continent and the sea. Due to the frequency of extreme events such as storm surges, floods, etc. especially in coastal areas in the past decades, scientists are increasingly interested in the study of shoreline dynamics.
