Angle of Repose

"Angle of repose" is a technical term for the slope which a pile of
granular stuff forms when it is at rest. Here you see a stream which
was actively cutting across a beach, causing the sand to continually
crumble down the slope, even as I watched. I though it was neat that,
although the edge weaves in and out, the slope remains constant.
