A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its stream bed all year round during years of normal rainfall. `Perennial` streams are contrasted with `intermittent` streams which normally cease flowing for weeks or months each year, and with `ephemeral` channels that flow only for hours or days following rainfall.
