Homogeneous detached composite breakwater: CFD study of the design sensitivities in the 2D geometrical layout using a detached homogeneous low-crested structure to reduce sea wall overtopping

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...

A predictive view on Durbans flood safety: The Golden Mile protected in style

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...

Integral coastal defence for Malecón of Havana, Cuba

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...

A hybrid solution for the Galveston Seawall: A study on the reduction of the hydraulic loads by a sand cover at the Galveston Seawall with the use of XBeach

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...

Coastal protection Malecón seawall: A study to develop a sea defence solution that prevents unacceptable flooding and damage to the 'Malecón Tradicional' in Havana, Cuba

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...

Maintaining the waterfront in Vlissingen: Re-stitching the relationship between water and the urban fabric

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,...

Composite Seawall for Wave Energy Conversion

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...

Havanna city seawall: The Malecón in Havana, Cuba (workplan)

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...
