Desalination is the process of removing salt from water. It is used to produce fresh water from seawater or brackish water. River basins are natural watercourses that drain water from a watershed into a larger body of water, such as a river, lake, or ocean. River basins provide a number of benefits, including flood control, water storage, and habitat for plants and animals. They can also be used to generate hydroelectric power. However, desalination is not a benefit of river basins.
