The process of adaptation related to physical environmental and social interaction systems changes on coastal morphodynamical

The morphodynamical change provides greater impact to the ecosystem, especially the coastal environment. Since the coastal region is vulnerable to environmental changes, this study aims to develop an adaptation models morphodynamical related to changes in the coastal area. The study adopts the AHP method to analyze the elements stated in the hierarchy. There are three levels builds Contain the adaptation models based on morphodynamical changes as the objective, three criterion, and three alternative strategies. The factors the which influence the strategy of preference are a socioeconomic impact, the environmental sustainability, and social network. However, the morphodynamical changes involve; the human activity, so the demography growth contributes in the process of change. The population growth has increased every year, and most live in coastal areas leading to Increased human activity in coastal areas, especially in the utilization of natural resources and coastal ecosystems. Various kinds of human activities are conducted both on land and at sea contributed to the changes in the environment. The interaction between community creates another challenge that should be solved to preserve the environmental sustainability. The limited ability of the environment, including in coastal ecosystems and their shoreline change the caused imbalances hazard that the sustainability of marine and coastal environment and the community as well.
