... of damage to coastal structures such as breakwaters.The interaction between breaking waves and the breakwater coast has recently attracted extensive research (e. g., Mazinani et al., 2015; Hayatdavoodi et al., 2016).Given that extreme waves often have significant nonlinearity, the linear and second-order...

... ABSTRACT Accurate simulation of wave evolution over a submerged trapezoid breakwater requires a high accuracy in both linear and nonlinear properties of the numerical model. The two-layer Boussinesq-type model with highest spatial derivatives being 2 (Liu et al, 2018) is derived with a mild...

... countries have begun to put effort into saltmarsh restoration projects. In 2016, more than 340 acres of coastal wetland area have been saved and reestablished in Braddock by constructing a barrier beach in the form of the breakwater with nature-based features, where the interior wetland erosion was reduced...
