The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...
Calculation of the reflected waves against obstacles is a prominent step in designing coastal structures. In addition, a complex process occurs during wave collision with beaches or breakwaters. These processes cause wave characteristics to be (energy dissipation, reflected wave, etc.). The new wave characteristics are dependent on reflected wave height straightly which are not measureable. In ...
Abstract Prediction of maximum wave height and the relative period as the fundamental parameters for assessment and design of offshore structures are forced with uncertainties. This paper proposes two algorithms for calculation of the probable extreme wave height in the Persian Gulf with respect to existing statics data in the South Pars region. A long-term joint distribution model of the co...
cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. usually failure of cylindrical tanks leads to serious consequences. during the past earthquakes such as 1964 alaska and 1999 turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. therefore, evaluation of seismic performance of these str...
Prediction of wave height is of great importance in marine and coastal engineering. In this study, the performances of artificial neural networks (feed forward with back propagation algorithm) for online significant wave heights prediction, in Persian Gulf, were investigated. The data set used in this study comprises wave and wind data gathered from shallow water location in Persian Gulf. Curre...
Safety of shipping is an ever growing concern. In a summary on shipping safety Douglas Faulkner investigates the causes of shipping casualties [1] and concludes that the number of unexplained accidents are far too high in comparison to other means of transport. From various sources, including insurers data over 30% of the casualties are due to bad weather ( a fact that ships should be able to c...
