Economic optimization of coastal flood defence systems including storm surge barrier closure reliability

Storm surge barriers are large movable hydraulic structures which close during a storm surge to prevent coastal floods. In the regions they protect, a failure to close the barrier is often the most likely cause for a catastrophic flood. Nevertheless, flood risk assessments usually only focus on raising flood defences behind the barrier....

New Guidelines for the Quality Control of Risk Analyses of Critical Hydraulic Structures

The efficacy of risk models and risk analyses critically hinges on sufficient model evaluation. Nevertheless, the usefulness for the intended purpose is rarely systematically assessed. Poor or even lacking model evaluation of the applied risk models and analyses also troubles the asset management of storm surge barriers in the Netherlands. In...

A Systematic Approach to Improve Reliability of Storm Surge Barrier Closures

Coastal defenses must be upgraded to combat increasing flood risk due to climate change and other factors. Storm surge barriers, large movable hydraulic structures that close temporarily during storm surges to prevent coastal floods, play a vital role in protecting estuaries. Due to the complexity of their risk analyses, important improvements...

Overview and Design Considerations of Storm Surge Barriers

The risk of flooding in coastal zones is expected to increase due to sea level rise and economic development. In larger bays, estuaries, and coastal waterways, storm surge barriers can be constructed to temporarily close off these systems during storm surges to provide coastal flood protection. Worldwide, 18 storm surge barriers have been...

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...

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.

Tidal power plant along the Western Scheldt

Getijcentrale in de Brouwersdam: Variantenstudie

Recentelijk bleek uit waarnemingen en onderzoek dat de afsluiting van het Brouwershavensche Gat ongewenste gevolgen heeft gehad voor de natuurwaarde van het gebied. Tevens wordt verwacht dat de situatie verder zal verslechteren wanneer geen corrigerende maatregelen worden genomen. Naar aanleiding hiervan is voorgesteld om de doorlaatcapaciteit...

The Energy Polder: Feasibility Study on a Tidal Power Plant along the Western Scheldt

In the Netherlands 6,8% of the total electricity production came from renewable energy sources. Electricity was 17 % of the total energy consumption in that year. In total 1,2% of the energy consumption was therefore renewable. The objective of the cabinet to get 20% of the energy from renewable energy sources will therefore be a major challenge...
