Floodplain

A floodplain is a low-lying area adjacent to a river, stream, or other water body that is prone to flooding during periods of high water flow. Floodplains are natural features of the landscape and are formed as a result of the gradual deposition of sediment carried by flowing water over time.河漫滩（floodplain）是毗邻河流、溪流或其他水体的低洼区域，在高水流量时期易发生洪涝。河漫滩属于自然地貌景观，其形成源于流水携带的沉积物随时间逐步沉积的过程。
