Tow-dimensional Modeling of Water Flow around Rigid Breakwaters in the Sea Beds with different slopes abstract
The breakwaters are among those important and costly offshore structures. Breakwaters are the structures made of concrete or a combination of these two, being built for the protection of coastal and offshore installations from the threat of danger of waves and the confrontation of their negative influence. About 50 years ago, mound breakwaters were built in the shallow waters. With the increase of goods exchanges, the necessity of extending ports and their size and due to the increase in the dimensions of vessels and crafts, the breakwaters were made in the deeper areas and places of sea and this resulted in the increase of the height of waves and the consideration of designing and executing issues and in this regard, a variety of breakwaters were considered regarding their structures and their stability. In the present study, the modeling of breakwater, with two different slopes in the sea bed and the water flow around it, was conducted using hydro-dynamic method of smoothed particles. The accuracy of the results was achieved using conducted works carried out by the America s Army Engineering Directorate and the gained results showed the appropriate conformity of numerical modeling with the results provided in the laboratory. Then, some changes in some of its parameters including the water depth, sharpness of the waves and the slope of the breakwaters and its influence on the rising rate of waves were put under investigation.
