Floods are natural occurring processes that are difficult to prevent but can be managed to reduce its social and economic impacts. Flooding is a threat to life and leads to damage of property. Therefore, it is very important that flooding risks be considered during any planning process. There are areas that are more susceptible to flooding than others.
Good planning and management can help in curbing the risks of flooding. In simple terms, flood risk analysis is an assessment of the various risks in relational to residential, industrial and commercial land uses. It is a requirement as part of any planning application for larger sites for development especially in areas that are in flood-prone areas. The analysis can also be used by insurers to act as a way of reducing premiums in insurance.
Flood risk analysis considers the impacts of flooding and how the proposed development project may affect the area. In addition, the analysis includes a recommendation on how the flooding risks can be improved after the development.These strategies help in that they reduce the vulnerability of the area to flooding.
The flood risk analysis requires information on the development of the area; existing and the proposed development information. This is important in determining whether the proposal will be allowed to proceed or not.
The analysis ensures that future risks caused by floods are avoided or can be managed and dealt with in good time and in an affordable way. The analysis is also, like an assessment that provides not only recommendations but also includes the management of the risks posed by floods.
Clearly, there are many significances of flood risk analysis. Whether the application is for a major commercial purpose, individual development purposes, industrial or even small extension of our residential land, analysis is inevitable.
Scope of the study
The one type of floods occurs in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While river basin flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry. In my study area is limited around analysis of river basin flooding.
