Which term refers to any narrow natural bed or channel through which the water flows continuously or intermittently throughout the year?

Understanding watercourses in maps often comes down to recognizing terms that describe the actual channel through which water flows, not just the size of the stream. An arroyo refers to a narrow natural bed or channel carved by water that can carry flow during rainfall, especially in arid or semi-arid regions. This makes it the best fit for the idea of a defined watercourse that may carry water either continuously or intermittently, depending on conditions. The other terms describe smaller streams or larger rivers, but they’re not specifically the named channel that forms the bed through which water travels in those climates, so they don’t align as precisely with the concept.
