fa بررسی دو بعدی آبشستگی و پایداری پنجه موج شکن توده سنگی با استفاده از مدل سازی فیزیکی شرايط محيطي و زيست محيطي Environmental Study مقاله پژوهشي Research Paper In this study two breakwater models with different conditions of bed, waves and water level are employed to analyze the toe stability and scour depth. The tests are conducted with regular waves. It is found that the scour depth in front of the rubble-mound breakwater depends on wave height, structure slope, water level and wave period, but the results reveal the effect of wave period toe is more than others. So that long period waves with more energy can be a threat for rubble-mound breakwater. Also the results of the toe stability and scour depth are given in the form of diagrams.
