The nature-based breakwater of floating emergent vegetation (BFEV) provides protection for water banks and various engineering structures from wave erosion. Compared with the convenient hard breakwater, BFEV is beneficial to resilient sustainable development rivers, lakes, coasts, marine areas because it free new pollution. As a unrevealed effect efficiency on attenuation are be investigated th...

The Bragg resonance (BR) of a reflection coefficient resulting from the propagation monochronic waves over periodically submerged breakwater was studied using non-hydrostatic numerical model SWASH (Simulating WAves till SHore). occurs when incident wavelength is approximately twice structural length periodic according to Bragg’s law and conditions. This study aimed investigate dynamics at water...

Composite vertical breakwaters are coastal structures used to defend port basins from waves in intermediate and deep water conditions. In order safely use the inner side of harbors, it is important limit wave overtopping. Parapet walls for this purpose. To improve hydraulic efficiency parapet wall with a fixed crown height, can be shaped giving rise recurved overhand toward sea. Its function de...
