Which feature is described as "Small Falls; Small Rapids"?

Explanation:
Small Falls; Small Rapids describes a stretch of a stream where the bed and gradient are just enough to cause water to tumble over small steps or rough surfaces, creating turbulence and minor vertical drops. That combination is what we call rapids. It highlights a flowing section with enough energy to produce whitewater-like movement, but not a full waterfall. This is different from a disappearing stream (where the water vanishes seasonally or underground), an intermittent stream (which doesn’t flow year-round), or a perennial river (which flows year-round). So the term aligns with the presence of small drops and rapid flow characteristic of rapids.
