What is a floodplain?

A floodplain is accurately defined as an area adjacent to a stream or river that is subject to inundation during flooding events. This geographical feature is crucial for understanding hydrology and flood management as it serves as the natural area where floodwaters spread when river or stream levels rise. Floodplains play a vital role in the ecosystem; they provide habitat for wildlife and support diverse vegetation. Additionally, they act as natural buffers, absorbing excess water and reducing downstream flooding impacts.

The distinction of floodplains is significant in stormwater management and urban planning, as recognizing these areas allows for better flood risk assessments and the implementation of appropriate land use strategies. Understanding where floodplains are located is essential for minimizing damage during flood events, thereby helping to protect communities and infrastructure.
