Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience.
A natural disaster is the highly harmful impact on a society or community following a natural hazard event. The term "disaster" itself is defined as follows: "Disasters are serious disruptions to the functioning of a community that exceed its capacity to cope using its own resources.
In the United States, compensatory mitigation is a commonly used form of environmental mitigation and, for some projects, it is legally required under the Clean Water Act 1972. Compensatory mitigation is defined by the US Department of Agriculture as "measures to restore, create, enhance, and preserve wetlands to offset unavoidable adverse ...
Mitigation planning identifies policies and actions that can be taken over the long term to reduce risk, and in the event of a disaster occurring, minimize loss. Such policies and actions are based on a risk assessment , using the identified hazards , vulnerabilities and probabilities of occurrence and estimates of impact to calculate risks ...
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
Mitigation is easily defined as prevention. Preparedness is the act of changing behaviors or processes to reduce the impact a disaster may have on a population or group. [6] Response is assembling teams or units of emergency service to the area of disaster. Finally, recovery aims to restore the area affected by the disaster to its condition ...
Natural Disasters are defined as the naturally occurring physical phenomena caused either by events that have immediate impacts on human health and suffering.These disasters include geophysical (earthquakes, landslides, tsunamis, volcanic activity); hydrological (avalanches and floods); climatological (extreme Temperatures, drought, wildfires ...
The type of managed retreat proposed depends on the location and type of natural hazard, [4] [5] [6] and on local policies and practices for managed retreat. In the United Kingdom, managed realignment through removal of flood defences is often a response to sea-level rise exacerbated by local subsidence.
