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 flood risk assessment (FRA) is an assessment of the risk of flooding from all flooding mechanisms, the identification of flood mitigation measures and should provide advice on actions to be taken before and during a flood.

Managed retreat in the form of relocation has been used in inland and coastal areas in response to severe flooding and hurricanes. In the United States, this often takes the form of "buyout" programs, in which government acquires and relocates or demolishes at-risk properties.
Climate resilience is generally considered to be the ability to recover from, or to mitigate vulnerability to, climate-related shocks such as floods and droughts. [7] It is a political process that strengthens the ability of all to mitigate vulnerability to risks from, and adapt to changing patterns in, climate hazards and variability.
While flood control aims mainly on reducing or preventing the negative effects of floods, IFM aims on reducing the overall risk by means of land and water resources management with the goal of maximizing the benefits from the use of flood plains and minimizing the damage and loss of life due to flooding in a sustainable manner.
Environmental mitigation can be defined in various ways depending on the institutions and countries where the term is applied, or on the framework that is used to guide mitigation. For example, it may be defined as the process by which measures to avoid, minimise, or compensate for adverse impacts on the environment are applied. [1]
It is triggered for example by an overflow of rivers and lakes, flash flooding or snowmelt. During the flood, stormwater or water released from damaged water mains may accumulate on property and in public rights-of-way. It can seep through building walls and floors, or backup into buildings through sewer pipes, cellars, toilets and sinks.
