Designers of vertical seawalls and breakwaters have often included some form of seaward overhang (recurve / parapet / wave return wall / bullnose) as part of the structure with the design motivation of reducing wave overtopping by deflecting back seaward uprushing water. Despite a lengthy track record in the field and relevance to current design issues, very little generic guidance is available for their incorporation into seawall / breakwater design. This paper reports a study whose aim is the… 

Crown Wall Modifications as Response to Wave Overtopping under a Future Sea Level Scenario: An Experimental Parametric Study for an Innovative Composite Seawall

The overtopping phenomenon at the rear side of breakwaters has particular importance in harbor protection. Undoubtedly, this topic needs to be taken even more seriously, considering the sea level

Wave Impact Loads on Vertical Seawalls: Effects of the Geometrical Properties of Recurve Retrofitting

This study investigates the variation of wave impact loads with the geometrical configurations of recurve retrofits mounted on the crest of a vertical seawall. Physical model tests were undertaken in

ABSTRACT: The shoreline erosion is a major problem that persist world wide and seawall still remain as one of the most widely adopted coastal protection structure. The design of an efficient seawall

Experimental Study for Overtopping Discharges of Sea Dike having Low Mound and High Wave Wall (LMHW)

Overtopping discharge for sea dike having low mound and high wave wall (LMHW sea dike) is investigated with hydraulic experiments in this study. Vertical, Flare and Bullnose type wave walls are

Influence of Parapets on Wave Overtopping on Mound Breakwaters with Crown Walls

Numerical tests were conducted using computational fluid dynamics (CFD) to analyze the influence of nine crown wall geometries and found that low values of ep and wp/hp ≈ 1 produced the highest parapet effectiveness to reduce the mean wave-overtopping discharges.

WAVE OVERTOPPING OF RUBBLE MOUND BREAKWATERS WITH CREST ELEMENTS

Crown walls or superstructures on top of permeable breakwaters are often used as a measure in existing structures to counteract insufficient design protection against overtopping. These crest

After an extensive series of 2-D model tests on the overtopping response of various caisson breakwaters, general conceptual design formulae and graphs have been derived which relate the mean

Influence of parapets and recurves on wave overtopping and wave loading of complex vertical walls

Increasing sea water levels and storminess has intensified the need for structural measures to reduce wave overtopping without significantly raising the height of the wall. The use of recurves, wave

This manual draws together and summarises previous research into the overtopping performance of seawalls. Data is re-analysed to provide a set of consistent design techniques, representing the most

Effectiveness of recurved wave return walls

Model studies have been carried out at a scale of 1:15 to measure the overtopping discharges for recurved wave return walls located on top of smooth, plain sloping seawalls. The measured discharges

Expected Rate of Irregular Wave Overtopping of Seawalls

SYNOPSISThe overtopping rate of seawalls by irregular waves can be estimated as the expected value of overtopping rate with regular wave data weighted with the distribution of wave heights. The
