HYDRAULIC INTERACTION OF THE PERFORATED SEAWALL AND SMOOTH SUBMERGED BREAKWATER

Coastal structures are used for transition of people and goods between sea and land and for protection of coast and internal waters. With an aim to provide safe transition of people and goods, calm sea should be ensured in front of coastline in order to achieve vessels without large movements and no-overtopping coastline. This work deals with special type of coastal structure which consists of two common types of structures: perforated seawall and submerged breakwater positioned in front of it. A new mathematical model was developed based on the experimental measurements of wave parameters between such tandem. Experimental investigations were conducted in wave channel for monochromatic and spectral waves varying length between constructions (1, 2m, 2, 4m i 6, 2m) and submergence of breakwater (0, 06m and 0, 1m). The total of 54 hydraulic tests were achieved varying wave and geometrical parameters. Using a new developed mathematical models for monochromatic and spectral waves the analyse of hydraulic behaviour of such construction is presented and comparison with some other coastal constructions (only solid seawall, solid seawall in tandem with submerged smooth breakwater).
