Risk to life due to flooding in post-Katrina New Orleans

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...

Storm Surge Barrier: Overview and Design Considerations

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...

Reconnaissance Level Studies on a Storm Surge Barrier for Flood Risk Reduction in the Houston-Galveston Bay

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...

An Idealized Meteorological-Hydrodynamic Model for Exploring Extreme Storm Surge Statistics in the North Sea

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...

Climate Change Adaptation in Tokyo Bay: The Case for a Storm Surge Barrier

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....

Risk to life due to flooding in post-Katrina New Orleans

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 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 risk-based approach the...

Report Galveston Bay: Flood Risk Reduction Barrier

The objective of this study is to provide suitable candidate solutions for a storm surge barrier in the Bolivar Roads as part of the Ike Dike system and provide recommendations for further research.

Sandy toont kwetsbaarheid van noordoostkust VS

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.

Alternatieve benadering voor maatgevende waterstanden Nederlandse kust

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...

Highlights of Dutch and US coastal graduation projects in the Mississippi Delta after Hurricane Katrina

Have a water crisis? Time to call the Dutch

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.

Risk to life due to flooding in Post-Katrina New Orleans

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...

Reconnaissance level study Mississippi storm surge barrier

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...

Coastal adaptation to climate change: A case study in Durban, South Africa

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...

Spraakwater: Water governance in de big easy, een lesje daadkracht voor een polderende Hollander in New Orleans

Hoogwater op de Mississippi anno 2011

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....

Zand-slibsegregatie

Dit rapport beschrijft de resultaten van de studie "Modellering van zand-slibsegregatie in de Nieuwe Merwede", uitgevoerd voor het Rijksinstituut voor Integraal Zoetwaterbeheer en Afvalwaterbehandeling (RIZA) van het Ministerie van Verkeer en Waterstaat. Als studiegebied heeft het RIZA gekozen voor de Nieuwe Merwede, een riviertak in het...
