Perennial is a stream or river that has a continuous loop of a flow in parts of a stream bed all year round during years of normal rainfall. A intermittent is a stream or river which carries water in a considerable portion of the time, but ceases to flow occasionally or seasonally because bed seepage and evaporation/transpiration exceed the available water supply.
That is a summarized form of what each stream are. In conclusion, the difference is the way the stream flows. Perennial is a circular stream that is steady all year long, while a intermittent stream is at a specific timing.
The terms are typically synonymous : )- the opposite of a perennial stream which flows year round.
=A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its bed all year round during years of normal rainfall. During unusually dry years, a normally perennial stream may cease flowing, becoming intermittent for days, weeks, or months depending on severity of the drought.=
A perennial stream flows during dry periods because it is fed by ground water, much like an effluent stream is.

An intermittent stream comes and goes, full or dry, dpending on the feeder rivers or lakes, the number of people tapping into the source for irrigation, dams,natural or man-made,rainfall and hot weather that can evaporate a low stream.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
The greatest invention of Mother Nature is rivers. There are many different streams that flow in different orders, some being perennial or intermittent. They all follow different stream drainage patterns and no two are alike. Some of them even contain waterfall which are a breathtaking sight to see.
