Koedijk, O.C. (author)
As a result of diminishing budgets for maintenance, the Dutch waterway authority Rijkswaterstaat is amongst others in search for economizing infrastructural facilities for commercial inland vessels along its waterways. One type of those facilities are the mooring constructions for line up- and waiting areas at lock approaches. Another type are...

The Pianc WG 141 is proceeding in the conception of Design Guidelines for Inland Waterways. WG 141 aims to produce its first draft in the end of 2015. Part of the forseen content are classification of waterways and the object of reference vessels. The role of those subjects will be presented and discussed in the Workshop, that WG 141 will give...

The Pianc Working group 141 is in progress to develop design guidelines for Inland Waterways. In advance of publication of the final report, this paper consists of paragraph 6.2 of the report to come. The possibility exists that the content of this paper needs to be revised to suit with the other (future) subjects in the framework of the final...

This paper demonstrates the sensitivity of morphological process-based models to the chronology of input wave conditions. In this research the effect of an emerged offshore breakwater on the morphology of the beach is investigated. A 30 day long morphological simulation with real time history of the wave (brute force - base case) is compared...

The importance of incorporating flexibility and adaptability in infrastructure is being increasingly recognized. Flexibility in infrastructure can prolong their economic lifetime by enabling them to adapt to the changed requirements. The objective of this paper is to examine if it is possible to incorporate flexibility in port infrastructure...

In July, 1959, the presence of gas in the subsoil of the Province of Groningen in the extreme NE part of the Netherlands was confirmed. Subsequently, it became clear that the mining of the gas would result in considerable subsidence and a disruption of the drainage system of an area adjacent to the North Sea, and situated already partly below...

A revetment of pattern placed elements, or a so called pitching, is used worldwide to protect shorelines and embankments. Also in The Netherlands more than 500 km of river, lake and sea dikes is protected by pitchings. Until the 60’s the design and construction of pitchings was based on experience. After the first damages on pitchings and the...

Recent research done the IPCC (2007) working groups and other organizations has sparked global concern over the possible impacts of climate change and corresponding sea level rise (SLR) upon coastal communities. In reaction studies were done (for example by Nicholls et al., 2008) to assess the vulnerability of coastal regions and get an...

Apart from many ecological advantages, mangroves in front of a coastal defence may lower the construction and maintenance costs of the defence. Although mangroves have hardly any reducing effect on water levels (and on tsunami impact) mangroves may significantly reduce wave attack on a coastal dike, and in this way reduce the cost of a revetment...

The present volatile environment continues to place new functional requirements on port infrastructure. As a result, the useful life of port infrastructure has reduced in recent years. Flexibility in infrastructure makes it possible to adapt them for new or changed use. The use of flexible and sustainable solutions infrastructures needs to be...

Current methods used to determine Coastal setback lines have several limitations. Furthermore, the historical practice of defining setback lines based on a single deterministic estimate is also proving inadequate with the emergence of risk management style coastal planning frameworks which require probabilistic estimates of coastal recession....

Tidal inlets are of great societal importance as they are often associated with ports and harbours, industry, tourism, recreation and prime waterfront real estate. Their behaviour is governed by the delicate balance of oceanic processes (tides, waves and mean sea level), and fluvial/estuarine processes (riverflow and heat fluxes), all of which...

Extensive laboratory experiments were carried out to investigate wave overtopping on seadikes with (vertical) crown-walls in Vietnam. It is shown that the wave overtopping reduction by walls is inadequately, although rather complexly, described by TAW-2002. A new approach has been developed, which can straightforwardly be incorporated in the...

The landware slopes of sea dikes in the north of Vietnam are steep and solely constructed by soil covered with grass due to the budget constraints and also the out-of-date design guidelines.The resistance against erosion due to wave overtopping of several grass covered slopes were tested with the Wave Overtopping Simulator to show if a slope...

In the ROCK MANUAL (2007) some guidance is given for the design of toes for breakwaters. However, for very shallow toes, as well as for very wide toes (or berms) this guidance is only marginally. Recently a number of shallow berms and toes have been constructed, partly with the intention to lower the height of the breakwater. These works showed...

In 2006 a Vietnamese Engineering Consultancy Company carried out a design study of a Naval Base at the location of the South of Doson Peninsula in Vietnam. A deterministic approach applied to the conceptual design of the breakwater system of the Naval Base resulted in a cross-section with a big armour layer and a rather low crest level. This...

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...

This paper intends to demonstrate the applications of artificial reefs to a broader readership concentrating on examples in coastal protection. In Germany, artificial reefs are not widely used as a coastal protection measure probably due to limited knowledge of the potential of this kind of structures. Reefs are not intended to ensure total...
