Which term best fits a watercourse that does not flow year-round?

• A. Perennial River
• B. Perennial Stream
• C. Intermittent River
• D. Disappearing Stream

Answer: (C)

When we classify watercourses by how long they carry water, the important idea is whether water is present throughout the year. A watercourse that does not flow year-round is described as intermittent. It carries water only during wetter periods or after rain, and it can be dry at other times. Perennial ones flow all year, so they don’t fit the situation. A disappearing stream isn’t a standard term for this pattern; it points to streams that vanish into the ground in some landscapes, which is a different phenomenon. So the term that best fits a watercourse not flowing year-round is intermittent.
