Stable Width of an Alluvial Channel
Publication: Journal of Irrigation and Drainage Engineering
Volume 123, Issue 1
Abstract
Alluvial channels, in the context of this paper, are unlined man-made channels with predetermined bed slopes used to convey water that carries sediment. An extremal hypothesis is presented, namely, an alluvial channel attains a stable width when the rate of change of unit stream power with respect to its width is a minimum. An easy-to-use width control parameter is presented and compared with a form of Lacey's silt factor. The hypothesis is tested on data from canals located in the Punjab and Sind provinces of Pakistan.
