WebStraight channels, mainly unstable, develop along the lines of faults and master joints, on steep slopes where rills closely follow the surface gradient, and in some delta outlets. Flume experiments show that straight channels of uniform cross section rapidly develop pool-and-riffle sequences. Pools are spaced at about five bed widths.

WebIn open channel flow, the wetted perimeter is defined as the surface of the channel bottom and sides in direct contact with the aqueous body. Friction losses typically increase with an increasing wetted perimeter, resulting in a decrease in head.
