Noun: 1. A watercourse, typically a small stream or creek, that is often dry except during periods of rain. An arroyo is a channel or gully carved by water, commonly found in arid and semi-arid regions. It is characterized by having steep, sometimes vertical banks and a flat, sandy or rocky bed that may contain water only seasonally or after heavy rainfall.
