Flooding is the most expensive natural disaster in the United States, and rivers cause hundreds of floods every year. The transition from the winter season to spring can result in increased rainfall and melting snow which can cause rivers and other bodies of water to rise, overflow and spill out onto nearby flat, dry land—and that causes flooding.
