Coastal zones are exposed to the continuous action of several factors such as wave height and direction, wind speed, water depth, sediment dynamics, relative sea level change, rainfall and storm surges. All these natural factors make coastal areas highly vulnerable.

Why are coastal areas vulnerable?
The threat of rising sea levels as a result of climate change makes coastal resources, coastal infrastructure, and population living in coastal areas highly vulnerable. ... The objective of this study is to assess the relative vulnerability of coastal districts of India to present-day and future climate threats.
Why do coastal areas have high natural hazard risk?
Erosion occurs when, but not limited to, along shore currents, tides, sea level rise and fall, and high winds. ... Coastal erosion has been increasing over the past few years, and it is still on the rise, which makes it a major coastline hazard.
What is coastal vulnerability?
Coastal vulnerability is a spatial concept that identifies people and places that are susceptible to disturbances resulting from coastal hazards. Hazards in the coastal environment, such as coastal storms and erosion, pose significant threats to coastal physical, economic, and social systems.
How does climate change affect coastal areas?
Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
What causes coastal hazards?
Coastal hazards refer to the risks of life and property on the coastline that are created by coastal flooding, high winds and waves, short- and long-term shoreline erosion, and storm surges.
What are the main causes of coastal erosion?
Coastal erosion is typically driven by the action of waves and currents, but also by mass wasting processes on slopes, and subsidence (particularly on muddy coasts).
Is coastal erosion a natural hazard?
It's no secret why so many of us choose to live in coastal regions. These are areas of great bounty and beauty. The downside? These areas are also prone to many natural hazards such as erosion, harmful algal blooms, big storms, flooding, tsunamis, and sea level rise.
Why some cliffs can be eroded rapidly by the sea?
Sea cliffs are steep faces of rock and soil that are formed by destructive waves. Waves crashing against the coastline erode until a notch is formed. The erosion of this notch undercuts the ground above it until it becomes unstable and collapses. This process repeats itself and the sea cliff will continue to retreat.
How does coastal erosion affect the environment?
Some impacts are specific to coastal areas. For example, rising sea levels combined with storm surge is likely to cause accelerated erosion and increased risk of inundation. ... For ecosystems, sea level rise may lead to loss of habitat, and salinization of soils may cause changes to the distribution of plants and animals.
How does pollution affect the coastline?
Ecological consequences of pollution in coastal rivers and estuaries include loss or change of biodiversity , habitat , ecosystem function and ecological processes (Johnston & Roberts 2009, Johnston et al. 2015).
Is it healthier to live by the sea?
A recent UK study showed that, even discounting factors like age and economic factors, people who live by the sea are healthier than those who live away from the coast. Sea air encourages respiratory health, while sun exposure (with a healthy coating of SPF) is great for getting your daily dose of Vitamin D.
Is it healthier to live by the ocean?
Research finds that spending time by the ocean is pretty good for your wellbeing. In fact, according to an analysis of English census data published in the journal Health Place, those who live by the coast report better physical and mental health than those who don't.
Is it better to live by the sea?
Clearly, living by the sea is more calming than staying in towns and cities. ... This is because the sea is all natural and provides a sense of space, openness and fresh air. Historically, patients were often sent away for holidays by the sea to help improve their health. These uncrowded places can reduce stress levels.
