Abstract:
Landscape of Kulon Progo coastal area is very attractive with abundance natural resources and adequate accessibility. On the other hand, this landscape provides a challenge for the new airport development planning. This area is composed by mountains, hills, coastal areas, and flood plains which potentially results in various hazards. All potential hazards may become disaster that could potentially lead to damage and loss to various vital infrastructure and vulnerable elements. An integrative and comprehensive study regarding multi-hazards that may occur is necessary. Development planning should be integrated with disaster risk assessments, so the research on multi-hazards in the site plan of the new airport of Yogyakarta is very important. This research has three main goals: 1) to identify the relationship between landscape characteristics with the potential hazards that may exist, 2) to identify the type of hazards in each unit of landforms in the study area, 3) to identify the potential multi-hazards in the study area. This research used survey method, i.e. by landform analysis through image interpretation and compilation of supporting data to generate a multi-hazards map. The preliminary finding of this research indicated that landscape has a specific characteristic and it is correlated with one or more potential hazards. Some coastal hazards occur in fluvio-marine landform are tsunami, storm surge, and windstorm. In fluvial landform the hazard than commonly found is flood and wind storm. Earthquake may happen in both landform types. The multi-hazards type in the research area can be divided into two types, i.e. (i) collateral multi-hazards, such as earthquake that trigger tsunami, and (ii) simultaneous hazards, indicated several hazards occur in the same time but no correlation among them. For example, flood, wind storm, and storm surge happen in the same time triggered by hydrometeorological phenomena. The output of this research are multi-hazards map and integrated analysis report regarding multi-hazards analysis based on landscape approach.
