Ecological Risk Assessment of Construct Artificial Islands by Fault Tree Analysis Method in the Persian Gulf

Development is inevitable in various sectors.One example of these developments is the construction of artificial islands which is man-made and is made for variety of purposes including tourism, economy, and airports, industrial, political and military establishment. Construction of artificial islands is a serious treatment for marine ecosystems. In this way according to the geopolitical situation and the crucial role of Persian Gulf in the region, this golf is not safe against the effects of artificial islands construction and as a valuable ecosystem with high biodiversity has been threatened. Due to the growing trend of construction artificial islands in the Persian Gulf and importance of environmental risk assessment of these structures to analyze the relationships between the various stages of construction and environmental Persian Gulf, Fault Tree Analysis (FTA) was used in order to risk assessment of these structures. As a result it will follow path errors from an event or adverse condition (Top event) to achieving error or causal factors or initiator. The most important risks in Construction artificial island projects include: disorder in food chains, water pollution, hydrodynamic regime changing and damage to plant and animal species. Therefore for achieving sustainable development in the Persian Gulf, deciding about the construction of artificial islands must be more carefully and should be tried to reduce occurrence probability and severity of impacts.
