Structural design report for LCS (low crested structures): Final report

This report presents additional information and new formulae not included in Delos report D22. Existing formulae for the design of LCS's for coast protection structures can be found in D22 and are therefore not repeated in this report.

2D and 1D numerical model simulations for the effect of a single detached breakwater on the shore

The developmeot of the coastal area is oeeded for tourism and commercial purposes for a country located nearby a coast. Coastal development may lead to local erosion of the shoreline. Coastal defence structures, like an offshore breakwaters, may be used to solve tbis problem. An offshore breakwater is a breakwater parallel to the shore and...

Applicability of numerical models in simulating morphological changes due to offshore breakwaters

Present strategies for coastal defence in the Dutch coast are mainly focused on conventional solutions such as revetments, dunes, dikes, groynes as well as on beach nourishment. No attention has so far been paid to the implementation of Offshore Breakwaters. An offshore breakwater is a shore parallel structure which is constructed seperately...

Evaluation of Negombo offshore breakwater scheme

This brief report deals with both the pre and post implementation of the Negombo offshore breakwater scheme in west coast of Sri Lanka and is published with the collaboration of Ministry of Public works (Rijkswaterstaat), Netherlands and Lanka Hydraulic Institute, Sri Lanka, as a partial fulfilment of a MSc study carried out at International...

Influence of offshore breakwaters on coastal sediment transport rate and coastline morphology

Offshore breakwaters have been used in many coastal areas for coastal protection with greater or lesser success. However to date these have not been used along the Dutch coast for this purpose. This is probably due to the absence of accurate design tools for their functional design, coupled with the uncertainty of whether this method of coastal...

Engineering Design Guidance for Detached Breakwaters as Shoreline Stabilization Structures

This report summarizes and presents design knowledge for both the functional and structural design of detached breakwaters for shoreline stabilization. Functional design of break:waters in the United States relies on a significant amount of engineering judgement, data from a few existing breakwater projects for comparison, and an understanding...

Onderzoek naar de toepasbaarheid van offshore golfbrekers langs de Nederlandse kust

Allereerst worden in een korte probleem-analyse de belangrijkste elementen voor het gevraagde onderzoek uiteengezet (hoofdstuk 2), resulterend in een pakket van eisen waaraan enerzijds de constructie in principe zal moeten voldoen en anderzijds de (potentiële) lokatie(s). In het daarop volgende hoofdstuk 3 wordt een voorstel gedaan ten aanzien...

Defense of Shorelines by Structural Approaches

Structural approaches can be employed to stabilize shorelines against erosion, to provide sheltered areas for swimming or for a myriad of other benefits. In this section, the emphasis will be on shoreline stabilization although much of the information and discussions presented would be equally applicable to accomplish other objectives. Three...

Detached Breakwaters and their Use in Italy

Detached (or "offshore") breakwaters of emerging type are a common and effective approach for beach protection, particularly for areas with small tidal oscillations. This kind of breakwaters aims at acting on sediment transport by decreasing the transport capacity of long-shore currents, thus locally causing settlement of sediments. Unlike...

Detached Breakwaters

In this paper, the hydraulic functions and stability of detached breakwaters and submerged breakwaters with wide crown widths are discussed. The following subjects with regard to detached and submerged breakwaters are discussed: - Function of detached breakwaters in controlling waves and wave-induced currents - Function of detached breakwaters...
