A river is formed when water draining from mountanous terrain or some other watershed flows into a valley via smaller streams. The streams join together and their combined volume of water forms a river with the force of the water cutting a channel as it flows downhill toward a lake, sea, or ocean.
Rain causes a river to flood. A significant amount of rain causes the height of the river to rise and the river overflows onto land.
