This study treats a detached homogenous low-crested structure (HLCS) made of Cubipod concrete elements placed seaward of a vertical wall (forming a basin in between) to reduce overtopping. Assessing the complex hydrodynamics and effects of changing the geometry of such a system in relation to overtopping reduction is challenging. The...

Conventional rubble mound structures such as breakwaters, seawalls, and revetments are the most common type of coastal structures around the world used to protect harbour basins and embankments from wave action. To have a safe and economic design, two aspects need to be considered. The first one is the structural stability where the required...

During storms, ensuring the protection of people, vehicles and infrastructure on the crest of coastal structures from wave overtopping hazards is crucial. The thickness of the wave overtopping layer is a key variable used for assessing safety and maintaining a secure design. Traditionally, this parameter is associated with the height...

Seawalls play a significant role in protecting coastal areas against wave attack and flooding. The accurate estimation of wave overtopping at seawalls is therefore crucial to adequately protect people and infrastructure in these regions. In this study, the mean wave overtopping rate at rubble mound seawalls was investigated through 140 small...

For a safe design of a rubble mound seawall, overtopping characteristics such as the mean overtopping discharge (q) and the maximum individual overtopping volume (V<sub>max</sub>) should be limited. Unlike q, the estimation of V<sub>max</sub> is more complex and requires a wave-by-wave analysis of overtopping as well as a statistical analysis...

Tidal flats play an important role in the geomorphological and biological dynamics of coasts. Research on the morphological evolution of tidal flats constitutes one of the key research issues pertaining to the sustainability of coastal ecosystems and related coastal defense issues. In this work, a novel indicator, the surface tidal trail (STT...

This work presents the results of an investigation on how wave overtopping at a near-vertical seawall at the back of a sandy foreshore is influenced by sequences of erosive storms. The experiments were carried out in the Large Wave Flume (GWK) at Leibniz University, Hannover (Germany). The tested layout consisted of a near-vertical 10/1...

Estimation of the mean overtopping discharge is a major task in the design and assessment of the crest level of rubble mound structures such as breakwaters and seawalls. The tolerable mean overtopping rates are given based on the associated risk and wave characteristics. Several empirical formulas have been developed for the prediction of...

Lashley, Christopher H. (author)
Coastal communities across the globe are often protected by structures, such as seawalls, levees or dikes, which allow only a safe volume of water to pass over or “overtop” them due to wave action during storms. The area seaward of these structures is often characterised by shallow, gently sloping beds referred to as foreshores.<br/>As storm...

In this research OpenFOAM is used to model and determine the complex hydrodynamic behaviour of a Homogeneous low-crested structure (HLCS) consisting of cubipod artificial concrete elements. The validated model is used to gain insight in the design sensitivities of a two dimensional cross sectional layout to reduce sea wall overtopping. HLCS and...

Durban is the third largest city of South-Africa, located in the province of KwaZulu-Natal. The city suffers from severe floods from time to time, finding its cause in both the Indian ocean as well as the Umgeni river. The eThekwini municipality wishes a better insight in the occurrence of these floods and searches for a structural solution to...

This report contains a study for the Integral Coastal Defence System for the Malecón in the city of Havana, Cuba. The objective was to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Deriving solutions from earlier reports and using old and new data, a solution is proposed...

The City of Galveston is protected from extreme storm impact by a 17-km concrete seawall facing the Gulf of Mexico. Recent investigations have shown that the seawall may not be sufficient any more to protect against a 1 in 100 year design storm. Since raising the seawall disconnects the city from the beach and may be very costly, a hybrid...

This report presents a study of the Malecón Tradicional in front of ‘Centro de Havana’ and ‘Havana Vieja’ in the city Havana, Cuba. The objective is to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Implementing the recommended solutions reduces the overtopping sufficiently...

From a unique seaside town Vlissingen has developed into a generic fragmented coastal city. The main assignment in Vlissingen is to counter this fragmentation. Given the historical importance of the water for Vlissingen, it is re-introduced to function as connector of the different fragments of the city. One of these fragments, the Spuikom area,...

Detrimental impacts of fossil fuels and its foreseen scarcity are encouraging research for the development of the renewable energy as alternatives. A newly developed composite seawall concept could be a vitally important technique for wave energy conversion. A 3-D model of composite seawall has been simulated to comprehend its hydraulic...

In most developed coastal areas, seawalls protect towns, road, rail and rural infrastructure against wave overtopping. Similar structures protect port installations worldwide, and may be used for cliff protection. When a large tidal excursion and severe environmental conditions concur to expose seawalls and vertical face breakwaters to wave...

Prediction of wave overtopping discharges for seawalls / breakwaters have improved significantly over the last 25 years, but processes associated with overtopping hazards to people on or close behind seawalls are not yet well understood. Despite research advances in recent years, there remain important gaps in knowledge and disagreements over...

Havana City is situated on the north coast of the Republic of Cuba, the largest island in the Caribbean Sea. Because of Spanish and African influences Havana is one of the most picturesque cities of the western hemisphere. In the 18* and 19* century a part of the city that lies adjacent to the sea, the Malecón, has developed until today into a...
