What causes recurrent tidal flooding?
Coastal flooding can result from a variety of different causes including storm surges created by storms like hurricanes and tropical cyclones, rising sea levels due to climate change and tsunamis. Storm surge from Hurricane Carol in 1954

- Managing The Risk
Rising global temperatures are leading to global sea level rise by causing the melting of glaciers and the land-based ice sheets in polar regions, as well as the thermal expansion of ocean water. Since 1993, global sea level has been monitored by satellites, which show that it is currently rising at an average of 3.3 millimetres per year, an accel...
The actual impact on sea levels around the UK coastline depends on several factors, including the Earth’s rotation, oceanic circulation and local geological changes. A major factor for the UK is that the land is still adjustingvery slowly to the retreat of the ice sheets at the end of the last Ice Age, which ended around 12,000 years ago: parts of...
There are many ways in which the UK can adapt to these growing impacts. These include using ‘hard engineering’ to maintain and strengthen existing structures such as sea walls in a policy approach called ‘hold the line’, and building new defences further out from the coastline to ‘advance the line’. The Southsea coastal schemeon the Hampshire coas...
- Flooding Facts. What is a flood? A flood is the accumulation of water over normally dry land. It’s caused by the overflow of inland waters (like rivers and streams) or tidal waters, or by an unusual accumulation of water from sources such as heavy rains or dam or levee breaches.
- Flooding Causes. Many factors can go into the making of a flood. There are weather events (heavy or prolonged rains, storm surge, sudden snowmelt), and then there are the human-driven elements, including how we manage our waterways (via dams, levees, and reservoirs) and the alterations we make to land.
- Flood Consequences. When flooding inundates a home or community, it upends lives and introduces a litany of potential short- and long-term consequences.
- Flood Preparation. Advance preparation for a flood can save your property or even your life. (See FEMA.gov for a comprehensive flood preparation list.) To stay safe, take these precautions
Jan 20, 2021 · Coastal flooding is when land is flooded with sea water. Extreme weather and high tides can cause a rise in sea levels, and the water goes into surrounding areas and causes flooding....
Jun 18, 2021 · Climate change and anthropogenic pressures are widely expected to exacerbate coastal hazards such as episodic coastal flooding. This study presents global-scale potential coastal overtopping...

Apr 16, 2020 · Here, we investigate the continuous shift in coastal flooding regimes by quantifying continuous rates of increase in the occurrence of extreme water-level events due to sea-level rise.
Nov 25, 2021 · SLR exposes coastal populations to a spectrum of impacts with broad spatial and temporal heterogeneity, but exposure assessments often narrowly define the spatial zone of flooding. Here we show...
