ABSTRACT
As used in this text, the term open channel flow covers the range of natural and artificial conveyances of water in settings that are open to atmospheric pressure. Some examples of open channels include water flowing in creeks and rivers, through irrigation canals, within open air conveyances in wastewater treatment plants, and along the curb and gutter at the edges of streets and parking lots. The channel, therefore, varies from a natural surface lined with naturally occurring sediment to a man-made surface made of concrete, metal, or graded soil and sediment.
