Tsunami, like many other natural disasters leaves people a short time for escape. When talking about Tsunami, the escape time is the period it takes for the wave to start moving from the epicenter, change into a giant wave gradually and reach to a cost. In order to minimize damages of this phenomenon, the escaped time has to be estimated without delay. For this purpose the first needed action is modeling the Tsunami waves. Analytical and numerical models and software that are designed based on them do exist. To have an efficient and rapid Tsunami alarming system all of these options are examined in this project. Then having a reliable model quite a few probable scenarios are propounded. The... 

The ocean thermal energy conversion system is one of a variety of renewable marine energy that is made up of a thermodynamic cycle, and it uses the difference between the temperature of hot water at the ocean surface and cold water at the depths of the ocean to generate electricity. The closed cycle is one type in which the system uses a working fluid which its boiling point less than the boiling point of water. Increasing the temperature of the fluid inlet in the cycle increases the system efficiency, which has been applied in this study to increase the efficiency of the OTEC system. The required energy to increase this temperature has been achieved by adding a solar collector to this... 

Super cyclone GONU formed on June 2007 has been recognized the strongest tropical cyclone in the North Indian Ocean (NIO). The aim of this study is to numerically simulate the cyclone GONU and its resulting waves in the southern seas of Iran leading to the best parametric model to simulate future occurrence of tropical cyclones (TCs) in the NIO. In this regard, the best track data of the cyclone is extracted from Indian Meteorological Department (IMD). The cyclone GONU wind field is simulated by Young and Sobey, Holland, and Rankin models in order to determine the most appropriate model which is then considered for regenerating cyclonic wind fields over the Makran coastline and the sea of... 

The use of clean energy sources has become increasingly popular around the world in recent years. One of the most important of these sources is wind energy. Due to the high wind potential in offshore areas than on land, this study uses the integration of multi-criteria decision-making methods and GIS to identify the best areas for developing offshore wind farms in the Persian Gulf and the Sea of Oman. Criteria applied in this study are divided into two categories: restrictive criteria, such as recommended transportation routes and anchored restricted areas, and technical criteria, such as wind speed and water depth. After removing the inappropriate areas using restrictive criteria, the...
