Definition of "water-rolled" [water-rolled]

• Rolled along by water: specially applied to boulders or pebbles which, beginning as angular masses, have had their corners worn off by being rolled along in a current of water. Rounded water-rolled pebbles may thus be contrasted with angular glacial pebbles.
