Abstract

Coastal zone is an area between two ecosystems with independent characteristics, which is considered as a separate planning unit. In this area, the analysis of natural hazards is an essential tool in decision-making, planning and prioritization of crisis management actions. The most important action in this analysis is determining the types of hazards. In this study, the investigation of natural hazards in the coastal zone of Sistan and Baluchistan province related to the objectives of the Integrated Coastal Zone Management (ICZM) plan was carried out. For this purpose, firstly all possible hazards in coastal zone were determined using the Delphi method and classified after identifying the scope of its impact. In order to analyze the influence area of each hazards, all related activities were identified and their influence was determined by forming a hazard-use matrix. Finally, an overall map was prepared by overlaying layers in GIS, and the number of all hazards which threaten activities was determined. The results showed that the largest number of hazards are located in the western part of Sistan & Baluchistan coastal zone between Pozm Bay and Khor-e Maydani. Also, Tsunami and sand dunes are two dangerous hazard, which affect all activities. Among all possible landuse, agricultural and dry farming are more affected activities by natural hazards. The results of this study, by determining of hazard influence areas and by using them in determining the vulnerability of coastal zone, will cause the environmental management plan (EMP) of the study area prepared with a wider range of information and development measures will lead to a safer development in this region.
