A chute is a vertical or inclined plane, channel, or passage through which objects are moved by means of gravity. Landform. A chute, also known as a race, flume, cat, or river canyon, is a steep-sided passage through which water flows rapidly. Akin to these, man-made chutes, such as the timber slide and log flume, were used in the logging industry to facilitate the downstream transportation of timber along rivers. These are no longer in common use. Man-made chutes may also be a feature of spillways on some dams. Some types of water supply and  irrigation systems are gravity fed, hence chutes. These include aqueducts, puquios, and acequias. Building chute. Chutes are in common use in tall buildings to allow the rapid transport of items from the upper floors to a central location on one of the lower floors or basement. Chutes may be round, square or rectangular at the top and/or the bottom. An elevator is not a chute as it does not move by gravity. Chutes in transportation.
