A floodplain is a flat area of land next to a river or stream that becomes flooded when the water rises. These areas are important because they help absorb excess water, reducing the risk of severe flooding in nearby communities. Floodplains are often rich in nutrients, making them ideal for agriculture and supporting diverse ecosystems. During heavy rains or snowmelt, rivers can overflow their banks, spreading water across the floodplain. This natural process can create habitats for wildlife, such as birds and fish, while also replenishing soil fertility. However, human activities, like urban development, can disrupt these vital areas, increasing flood risks.
