Corrasion \Cor*ra"sion\ (k?r-r?"zh?n), n. [See Corrade.] (Geol.) The erosion of the bed of a stream by running water, principally by attrition of the detritus carried along by the stream, but also by the solvent action of the water.

n. 1 wear caused by wind-blown or water-borne sand 2 wear caused by stream-borne or glacier-borne stones 3 wear caused by collisions between stones under the influence of seaside breakers

n. erosion by friction [syn: abrasion, attrition, detrition]

Corrasion is a geomorphological term for the process of mechanical erosion of the earth's surface caused when materials are transported across it by running water, waves, glaciers, wind or gravitational movement downslope. An example is the wearing away of rock on a river or seabed by the impact or grinding action of particles moving with the water. The resultant effect on the rock is called abrasion.

Corrasion is third studio album released by the Canadian drone doom band Nadja. Originally released in 2003 and limited to 200 copies, the album was rerecorded and re-released with three bonus tracks on August 13, 2007.
