although there exist advanced models which predict beach profile for natural beaches, the behavior of the beaches in front of seawalls still suffers from the lack of appropriate theoretical models and sufficient measured data. in this paper, following the results obtained from the measurements, a beach profile evolution model is developed, using the measured probability distribution of the near...

This paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. The experiments of physical modeling of this research have been done in the flume of the Soil Conservation and Watershed Management Research Institute (SCWMRI). The waves applied to the structure model are irregular and ...

The numerical modeling of sediment transport under wave impact is challenging because the complex nature triple wave–structure–sediment interaction. This study presents three-dimensional scouring due to non-breaking on a vertical seawall. Navier–Stokes–Exner equations are approximated calculate full evolution flow fields and morphodynamic responses. bed erosion model based van Rijn formulation ...

It is more common to introduce the parapet/recurve/wave return wall over existing structure, such as a vertical seawall or composite reduce overtopping efficiently. The advantage of recurve on top sea has been studied in past regards wave interaction and overtopping. However, their efficiency protecting inland structure during extreme events flooding tsunami unexplored. present study addresses ...

A one-dimensional hybrid numerical model is presented of a shallow-water flume with an incorporated piston paddle. The hybrid model is based on the improved Boussinesq equations by Madsen and Sørensen (1992) and the nonlinear shallow water equations. It is suitable for breaking and non-breaking waves and requires only two adjustable parameters: a friction coefficient and a wave breaking paramet...

Understanding the spatial distribution of wave overtopping water behind coastal protection structures is essential for assessing safety level regions defences. The volume determines planning and arrangements critical infrastructures (e.g., railways, roads buildings) in regions. This study presents a series laboratory-scale physical modelling experiments to investigate plain vertical seawall wit...

The region of Saemangeum for this study is influenced by two major rivers, Dongin and Mankyung. Currently, a 33km long seawall has been constructed for the purpose of reclamation of 283km2 land area and fresh water reservoir area of 118km2 for the major national internal development project, planned for its completion by 2030. The Saemangeum provides an optimal location for tidal power generati...
