Answer 2

Natural vegetation, such as trees and plants, helps prevent runoff. In areas where vegetation has been removed by such processes as logging or construction, it must be replaced, a method known as reforestation. This is especially important in the headwater parts of a river's drainage basin. To help control flooding near a river's mouth, spillways are used. These are channels that run through the back swamps parallel to the main stream.
