Many names for small rivers are specific to geographic location; examples are run in some parts of the United States,  burn  in Scotland and northeast England, and beck in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. river begins at a source (or more often several sources) and ends at a mouth, following a path called a course. The water in a river is usually confined to a channel, made up of a stream bed between banks. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel.
