A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event.
The Delta Works is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine–Meuse–Scheldt delta from the sea. Constructed between 1954 and 1997, the works consist of dams, sluices, locks, dykes, levees, and storm surge barriers located in the provinces of South Holland and Zeeland.
Bridgwater Bay is on the Bristol Channel, 5 kilometres (3.1 mi) north of Bridgwater in Somerset, England at the mouth of the River Parrett and the end of the River Parrett Trail. It stretches from Minehead at the southwestern end of the bay to Brean Down in the north. The area consists of large areas of mudflats, saltmarsh, sandflats and shingle ridges, some of which are vegetated. It has been designated as a Site of Special Scientific Interest (SSSI) covering an area of 3,574.1 hectares since 1989, and is designated as a wetland of international importance under the Ramsar Convention. The risks to wildlife are highlighted in the local Oil Spill Contingency Plan.
The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales and South West England. It extends from the smaller Severn Estuary of the River Severn to the North Atlantic Ocean. It takes its name from the English city and port of Bristol.
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves.
A seawall is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides, waves, or tsunamis. As a seawall is a static feature, it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea.
The 1953 North Sea flood was a major flood caused by a heavy storm surge that struck the Netherlands, north-west Belgium, England and Scotland. Most sea defences facing the surge were overwhelmed, resulting in extensive flooding.
Kingston Seymour is a small village and civil parish with royal status in Somerset, England. It is situated within the unitary authority of North Somerset, between Clevedon and Weston-super-Mare on the North Somerset Levels. The parish has a population of 388.
Arlingham is a village and civil parish in the Stroud District of Gloucestershire, England. The 2021 Census recorded a parish population of 533. The parish contains the hamlets of Milton End, Overton and Priding. The next parish to the east is Fretherne with Saul.
The Severn Barrage is any of a range of ideas for building a barrage from the English coast to the Welsh coast over the Severn tidal estuary. Ideas for damming or barraging the Severn estuary have existed since the 19th century. The building of such a barrage would constitute an engineering project comparable with some of the world's biggest. The purposes of such a project have typically been one or several of: transport links, flood protection, harbour creation, or tidal power generation. In recent decades it is the latter that has grown to be the primary focus for barrage ideas, and the others are now seen as useful side-effects. Following the Severn Tidal Power Feasibility Study (2008–10), the British government concluded that there was no strategic case for building a barrage but to continue to investigate emerging technologies. In June 2013 the Energy and Climate Change Select Committee published its findings after an eight-month study of the arguments for and against the Barrage. MPs said the case for the barrage was unproven. They were not convinced the economic case was strong enough and said the developer, Hafren Power, had failed to answer serious environmental and economic concerns.
The Caldicot and Wentloog Levels are two areas of low-lying estuarine alluvial wetland and intertidal mudflats adjoining the north bank of the Severn Estuary, either side of the River Usk estuary near Newport in south east Wales. They are also known collectively as the Monmouthshire Levels or Gwent Levels, and the name Wentloog is sometimes spelled Wentlooge in official publications.
Tsunamis affecting Britain and Ireland are extremely uncommon, and there have only been two confirmed cases in recorded history. Meteotsunamis are somewhat more common, especially on the southern coasts of England around the English and Bristol Channels.
The Church of All Saints in Kingston Seymour, Somerset, England dates from the late 14th or early 15th century. It has been designated as a Grade I listed building.
The climate of south-west England is classed as oceanic (Cfb) according to the Köppen climate classification. The oceanic climate is typified by frequent cloudy skies, cool winters with cool summers and precipitation all year round, with more experienced in winter. Annual rainfall is about 1,000 millimetres (39 in) and up to 2,000 millimetres (79 in) on higher ground. Exceptions include areas to the east of high ground ( e.g. Exeter / parts of West Somerset that are subject to a rain shadow effect and annual rainfall is closer to 30 inches.
The December 1981 windstorm was a severe storm that particularly affected southern England, Wales and south west France during 13 December 1981. The storm formed as a secondary low.
Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater. The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. The seawater can flood the land via several different paths: direct flooding, overtopping of a barrier, or breaching of a barrier. Coastal flooding is largely a natural event. Due to the effects of climate change and an increase in the population living in coastal areas, the damage caused by coastal flood events has intensified and more people are being affected.
Cyclone Xaver, also known as the North Sea flood or tidal surge of 2013, was a winter storm that affected northern Europe. Force 12 winds and heavy snowfall were predicted along the storm's path, and there were warnings of a significant risk of storm surge leading to coastal flooding along the coasts of the North and Irish Seas.
Cyclone Anne was a European windstorm which caused €75 million in damage across western Europe in early January 2014, followed days later by Cyclone Christina.
The 2013–2014 United Kingdom winter floods saw areas of Ireland and the United Kingdom inundated following severe storms. The south of England saw heavy rainfalls associated with these storms which caused widespread flooding, power cuts and major disruptions to transport. Economically, the worst affected areas were Somerset, Devon, Dorset and Cornwall in the south west and the Thames Valley in the south east.
