Rounak Afroz and Md. Ataur Rahman

In this research work the interaction between waves and horizontal slotted submerged breakwater has been investigated using numerical model.Two-dimensional numerical model based on the SOLA-VOF (SOLution Algorithm-Volume Of Fluid) method developed for wave interaction with fixed submerged breakwater has been updated in this research to study the wave interaction with horizontal slotted submerged breakwater. From the developed two-dimensional numerical model water surface profile, velocity components, magnitude of pressure around breakwater of different porosities (n=0.4, 0.5 and 0.6) and the value of F (VOF function) that represents fraction of volume occupied by fluid at any time are obtained. This study is expected to serve as a useful model to analyze wave deformation due to horizontal slotted submerged breakwater and will be important for designing submerged porous breakwater as a coastal protection measure.
