So the floods in Nigeria were really the most devastating in the country’s history -- and particularly affected the populated areas of the vast river plains of the Benue and Niger, destroying houses, bridges, farmland, killing numerous cattle.”
因此，尼日利亚的洪水确实是该国历史上最具破坏性的洪水——特别是影响了贝努埃河和尼日尔广阔河流平原的人口稠密地区，摧毁了房屋、桥梁、农田，杀死了无数牛。”
英语百科
Floodplain
A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge. It includes the floodway, which consists of the stream channel and adjacent areas that actively carry flood flows downstream, and the flood fringe, which are areas inundated by the flood, but which do not experience a strong current. In other words, a floodplain is an area near a river or a stream which floods when the water level reaches flood stage.
