A steep-sided channel resulting from accelerated erosion. A rill is generally a few inches deep and not wide enough to be an obstacle to farm machinery.
A small channel created by soil erosion and small enough to be obliterated by plowing.
Small channels that carry concentrated flow during runoff events and are dry most of the time.
a small channel (as one formed by soil erosion)
a very small brook, and in gardening terms it's a man-made and small-scale trickling canal or narrow channel
A rill is a very small channel of water, caused mainly by runoff water that eroded the soil.
A steep-sided small channel resulting from accelerated erosion; the most common form of erosion.
Small shallow intermittent water course or ditch with steep sides. No obstacle to tillage. e.g. rill erosion.
A small intermittent watercourse with steep sides, usually only a few inches deep.
A tiny drainage channel cut in a slope by the flow of water. Can develop into a gully with continuing erosion.
a small, eroded ditch, usually only a few inches deep and hence no great obstacle to tillage operations.
Small open topped gulley or water-course.
a shallow furrow eroded into the soil by runoff water
A small channel eroded into the soil by surface runoff; can be easily smoothed out or obliterated by normal tillage.
A rill is a narrow and shallow incision into soil resulting from erosion by overland flow that has been focused into a thin thread by soil surface roughness. Rilling, the process of rill formation, is common on agricultural land and unvegetated ground.
