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....

The Conceptual Design of the Bolivar Roads Navigational Surge Barrier

Hurricane Ike made landfall on 13th of September 2008 on the Galveston Island in the Texas area. This hurricane is the third-costliest hurricane that ever has made landfall in the United States and the costliest hurricane in the history of the Texas. The possible future disasters should be prevented by using the best practices and existing...

The joint impact of storm surge, fluvial flood and operation of man-made structures on the high water level frequency in the Lower Rhine Delta

Most deltas of the world and their highly urbanized environments, are vulnerable to flooding, and thus, the consequences in terms of human fatalities and economic losses are serious. Floods and the consequent damages have triggered significant developments of flood protection measures. Flood risk is expected to be much more serious in the future...

The Bolivar Roads Surge Barrier: A conceptual design for the environmental section

In response to the devastation caused by Hurricane Ike to the Galveston Bay Area, Texas, United States in September 2008, several proposals emerged to protect the region against future storm surges. One of them is a coastal spine called the ’Ike Dike’. A challenge for this 160 km [100 mi] long flood protection is to cross Bolivar Roads, a 2.8 km...

Hurricane Surge Risk Reduction For Galveston Bay

More than five years after Hurricane Ike devastated the Galveston Bay Area, the most critical challenge remains; reducing flood vulnerability. In response to Hurricane Ike’s disastrous impact, several structural flood risk reduction strategies have been proposed. Some advocating local solutions, others advocating system-wide coastal barriers....

Hindcast and validation of Hurricane Ike (2008) waves, forerunner, and storm surge

Hurricane Ike (2008) made landfall near Galveston, Texas, as a moderate intensity storm. Its large wind field in conjunction with the Louisiana-Texas coastline's broad shelf and large scale concave geometry generated waves and surge that impacted over 1000 km of coastline. Ike's complex and varied wave and surge response physics included: the...

Gulf of Mexico hurricane wave simulations using SWAN: Bulk formula-based drag coefficient sensitivity for Hurricane Ike

The effects of wind input parameterizations on wave estimations under hurricane conditions are examined using the unstructured grid, third-generation wave model, Simulating WAves Nearshore (SWAN). Experiments using Hurricane Ike wind forcing, which impacted the Gulf of Mexico in 2008, illustrate that the default and recommended setting for the...

Typhoon-induced extreme water levels near Singapore: A numerical model investigation

Due to the diminishing Coriolis force towards the equator, the equatorial zone is known to be cyclone-free. However, on 27th December 2001, a tropical cyclone Vamei was formed near Singapore; 1.4 degrees latitude North from the equator, and made a landfall about 60 km northeast of Singapore. Although this event did not cause any major...

Coastal response during the 1953 and 1976 storm surges in the Netherlands. Field data validation of the XBeach model

The storm surge early-warning system that is going to be established in the Netherlands, combines the accurate weather forecast with the hydrodynamic and morphodynamic models in an operational mode, in order to estimate the potential impact on the coasts. This study focuses on the morphodynamic validity of the operational model system, by...

Modelling the 1775 storm surge deposits at the Heemskerk dunes

After a storm surge in November 2007, older storm surge deposits were discovered in the eroded dunes near Heemskerk, the Netherlands. These deposits undulate in height with a maximum elevation of over 6 m above mean sea level. Luminescence dating suggests that the layers were deposited by either the 1775 or the 1776 storm surge. The aim of this...

Breach initiation by the response of coastal barriers during storm surges

The present paper is concerned with the processes of coastal barrier breaching with focus on the breach initiation induced by high activity of tropical cyclones in the northern and central coast of Vietnam. The breach initiation by the response of coastal barriers during storm surges can also be a common practice encountered in many coasts...

Impacts of Hurricanes Frances and Jeanne on Two Nourished Beaches along the Southeast Florida Coast

Site inspections and beacli profile surveys of nourislied beaclies in the city of Boca Raton, and Town of Palm Beach, Florida show that the nourished beaches protected the shore from hurricane impacts in 2004. Striking the southeast coast of Florida within 20 days of each other. Hurricane Frances (Sept. 5, 2004) and Hurricane Jeanne (Sept. 25,...

Cross-shore profile development during storm conditions: Analysis of field data gathered at Petten sea defence

The majority of population in the Netherlands live well below the mean sea level. At some locations people and infrastructures are only protected from the sea by a narrow stretch of sandy beaches and dunes, so reinforcement works will be necessary to prevent a break through during storm surges. Therefore it is necessary to study problems...

Transfer of ocean modelling capability to two scientists of the National Institute of Oceanography of India

Two scientists from the National Institute of Oceanography of India have been trained to use the storm surge model DUCHESS and the wave model DOLPHIN. The results are published separately in two reports. This is the first of them.
