Over the last three decades the beach area of Piçarras has undergone large changes. The river Piçarras was fixed which caused severe erosion problems. With large nourishment projects the municipality tried to create a sustainable beach area. However, these nourishments did not form a long term solution, which means that, until the present day,...

The Tam Giang-Cau Hai lagoon system, lying in the Thua Thien-Hue province in central Vietnam, is affected by a tropical monsoon climate. This among others is the reason the Cau Hai Lagoon area has a long history of floods and other water related problems. Inhabitants are very dependent on the lagoon, as the main sources of income of people...

Pipelines and cables on the sea bottom are usually protected by a cover of dumped rock. In case of maintenance or removal works, this cover has to be removed in order to expose the pipeline. This removal can be performed by means of a mass flow excavation process, created with a submerged jet flow. However, the exact erosion processes of a...

Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...

The Afsluitdijk is unable to withstand the future conditions that belong to an annual probability of occurrence of 1/10 000 per year for water level and wave conditions. Solution of Rijkswaterstaat is to strengthen the dike according to the principle of the wave overtopping resilient dike (NL: Overslagbestendige dijk). Therefore the Afsluitdijk...

The city of Itajaí is located in the province of Santa Catharina in Brazil. The people of Itajaí have been coping with flood risk for the past decades. During normal conditions the Itajaí-Açu River is a rather calm river that is used for navigation and the harbour area. Recovering from the past two floods in 2008 and 2011 have cost more than...

In this study, a probabilistic vulnerability assessment to the impact of storms in the coast of Thrace, Greece was carried out. To this end, the methodology presented by Bosom and Jiménez (2011) has been applied with some modifications. The introduced modifications, for this work, were the use of a different run-up model to deal with the...

This research focusses on the behaviour of fine particles which pass through the armour layer of bed material of the upper and middle reaches of a river. When the fine particles are entrained in the armour layer, it is described as ‘winnowing’ or vertical entrainment. A river bed generally consists of a coarse surface layer, which is the...

This master thesis aims to determine the best design option and the feasibility of an artificial sandy beach along the Old Boulevard of Batumi, Georgia. The coastline south of Batumi is affected by erosion problems. The coastal stretch between the port in the north and the Chorokhi River south of Batumi should be protected. In 2010 Alkyon...

An overdose of sediment from the Cilalawi River is going into the reservoir Waduk Jatiluhur. This is resulting in the problem of reservoir capacity reduction. With water still coming from different rivers, the future will be inundation. In this matter the recommendation for this problem is check dam(s) and changing land use, stated by the local...

Due to the closure of the Haringvliet in 1970 as part of the Delta works and the opening of the Beerdam in 1997, the course of the tidal flow in the Rhine-Meuse delta has changed. The tidal flow from and towards the Haringvliet is now completely taking place through the branches that connect the Haringvliet with the Nieuwe Maas and Nieuwe...

The Langmann reservoir is part of the hydropower system in the river Teigitsch and in the reservoir loss of storage volume occurs. The reservoir was therefore flushed, but recently no permission is granted. The reason is the high sediment concentrations that have negative effects on the downstream region. An optimization of the flushing...

The erosion problem at the Senegambia area (The Gambia) is the subject of this thesis. The Senegambia area is the largest Tourism developed area which contributes significantly to the economy of The Gambia. In November 2003 Royal Haskoning has constructed a beach nourishment of 1,000,000 m3 as an erosion buffer with a lifetime of 10 to 15 years....

It is common practice to protect subsea pipelines by embedding them into the soil. Trenches can be made before or after the pipelines have been laid. In the latter case, the excavation process is called post-trenching. The essence of post-trenching, as handled in this thesis, is erosion of sand by a water-jet. The literature study focused on the...

Against the background of enhanced hydraulic loads due to climate change there will be a need for improvement of the flood defence system in the Netherlands in the future. These days there is a growing interest in grass as a dike cover because it is a cheap and a sustainable dike protection. Yet at the moment there is a hiatus in the knowledge...

Groins are old and intuitive means of reducing erosion and are found along the coast worldwide, although according to CEM (Coastal Engineering Manual 2003), “they are probably the most misused and improperly designed of all coastal structures”. The original purpose of groins was to reduce local erosion, that is, to hold the width of beach in...

Coastal zones are highly vulnerable to climate change and its variability. Future projections of global climate change suggest that relative sea-level rise and increased storm frequencies could lead to significant increases in coastal flooding and shoreline erosion. Associated with this, it is likely that coastal hazards can have the potential...

Waihi Beach is a village consisting out of 2300 inhabitants, located in the Bay of Plenty on the North Island of New Zealand. It can be seen as a 9 km long tombolo beach. Dunes used to protect most of the land, but have decreased in size through natural erosive processes and through urban development in the dune areas. The long and short-term...
