Rivulets - a common word in your country?

Tweet

Tasmania is Australia’s wettest state and has dozens of rivers, creeks, streams and ….. rivulets! I’ve come across the word before but never seen it used in an official capacity as the name of a watercourse. The definition is that it is a small stream of water or other liquid. I didn’t manage to get a photo of any of the rivulets but this is another photo from the temperate rainforest near Strahan on the west coast of Tasmania. Felons who escaped from the penal settlement on Sarah Island were faced with wet, tangled conditions like this if they wished to escape. Although many tried to escape not too many succeeded. But getting back to rivulets, do you have named rivulets in your country?
