Experimental and Numerical Modeling of Wave Transmission Over Submerged Breakwater and Rigid Vegetation
https://orcid.org/http://orcid.org/0000-0002-7889-5655
The wave–structure interaction besides hydrodynamics over natural and submerged breakwaters is an empirical process due to the complex flow process. A better understanding of the wave transmission through natural and artificial submerged breakwaters is vital in the field of coastal conservation. The studies investigating transmission coefficient (KT), in general using phase averaging approach, in particular are limited. In this study, numerical simulations are carried out using one-dimensional Boussinesq wave model for submerged (i) broad dykes, (ii) narrow dykes, (iii) semi-circular breakwater and (iv) rigid vegetation. The validation of the model is done with a series of experimental observations carried out in two-dimensional wave flume for each breakwater. KT decreases with increasing wave steepness, relative crest width, relative water depth, relative crest free board for all kinds of breakwater configurations. In particular, KT was observed to be more for broad dykes and less for rigid vegetation. Model results were compared using physical model tests, and also with numerical and empirical models. Furthermore, wave transmission coefficients obtained from the laboratory model experimental investigation are in good agreement with the numerical simulations. Phase averaging approach gives more insight into the physical description of the wave–structure interaction over and around submerged breakwaters where limited experimental data is available.
