Coastal cities combine intensive socioeconomic activities and investments with high exposure to flood hazards. Developing effective strategies to manage flood risk in coastal cities is often a costly and complicated process. In designing strategies, engineers rely on computationally demanding flood simulation models, but they can only compare...

Since the catastrophic flooding of New Orleans due to Hurricane Katrina in 2005, the city's hurricane protection system has been improved to provide protection against a hurricane load with a 1/100 per year exceedance frequency. This paper investigates the risk to life in post-Katrina New Orleans. In a flood risk analysis the probabilities and...

Increases in typhoon intensity and sea level rise could pose significant challenges to coastal defences around Tokyo Bay. In order to analyse the extent of future problems the authors determined the increase storm surge that could result from an increase in typhoon intensity and sea level rise to this area around the turn of the 21st century....

In this study an overview of existing and planned storm surge barriers in the world is provided. A systematic analysis relates functional requirements (e.g. navigation and tidal exchange) to the main barrier characteristics (e.g. gate type, dimensions). Furthermore, as the costs of barriers are an important issue in the planning, available cost...

The Houston - Galveston area is at significant risk from hurricane induced storm surges. This paper summarizes ongoing studies on flood risk reduction for the region. Firstly, based on a simplified probabilistic hurricane surge model , the return periods of surges within the bay have been estimated. This model framework can be used to assess the...

This paper explores an alternative method to determine extreme surge levels at the Dutch Coast. For this exploration, specific focus is on the extreme water level at Hoek van Holland, The Netherlands. The alternative method has been based on a joint probability model of the storm characteristics at the North Sea. The intent of this method is to...

Eind oktober 2012 gebeurde wat al jaren was voorspeld: een orkaan treft een groot gebied in het noordoosten van de VS, met uitzonderlijk veel schade en meer dan 130 dodelijke slachtoffers. De vraag is of de Amerikanen meer aandacht gaan krijgen voor preventieve maatregelen.

In het najaar van 2011 is Thailand zwaar getroffen door overstromingen, met meer dan 800 dodelijke slachtoffers en ongeveer 45 miljard dollar directe schade. Nederlandse expertise werd ingeroepen voor het crisismanagement om de schade te beperken.

Het stormseizoen is weer begonnen in Nederland. De duinen en dijken langs de Nederlandse kust kunnen in deze periode zwaar belast worden door een combinatie van hoge stormvloed en zware golven. Op dit moment worden deze waterkeringen getoetst en ontworpen met waterstandsgegevens die vooral gebaseerd zijn op statistische extrapolatie van...

After the catastrophic flooding of New Orleans due to hurricane Katrina in the year 2005, the city’s hurricane protection system has been improved to provide protection against storms with at least a 100 year return period. The aim of this article is to investigate the risk to life in the post-Katrina situation for the New Orleans metro bowl. In...

This paper reports a reconnaissance level study of a storm surge barrier in the Mississippi River. Historical hurricanes have shown storm surge of several meters along the Mississippi River levees up to and upstream of New Orleans. Future changes due to sea level rise and subsidence will further increase the risk of flooding due to hurricane...

Tidal basins, as found in the Dutch Wadden Sea, are characterized by strong spatial variations in bathymetry and sediment distribution. In this contribution, the aim is at simulating the spatial sand-mud distribution of a tidal basin. Predicting this spatial distribution is however complicated, due to the non-linear interactions between tides,...

The Lagos coast has been suffering high rates of erosion since the construction of three harbour moles, i.e. the West Mole, East Mole and the Training Mole, at the tidal inlet connecting the Lagos Lagoon to the South Atlantic Ocean. To provide for a permanent erosion mitigation measure and to create residential and commercial area for circa 400...

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...

Afgelopen voorjaar was sprake van een bijzonder hoogwater op de Mississippi. De rivier voerde op haar hoogtepunt in totaal meer dan 65.000 kubieke meter per seconde af naar de Golf van Mexico, ongeveer vier keer zoveel als de 1/1.250 jaar ontwerpafvoer van de Rijn in Nederland, en overtrof op sommige plaatsen het historische hoogwater van 1927....

This paper discusses the application of a simple algorithm for the buffering of fines in a sandy seabed. A second layer is introduced in which fines may be stored during calm weather and from which fines may be resuspended during storms. The algorithm is applied first in a one-dimensional vertical (1DV) point model at a location in the North Sea...
