Critical Channel Dimensions for Open-Channel Transition Design
Publication: Journal of Irrigation and Drainage Engineering
Volume 137, Issue 11
Abstract
The channel dimensions leading to the critical state of flow are important in the design of channel transition. This work describes a methodology for determining the channel dimensions leading to the critical state of flow to maintain given specific energy or specific force conditions. The developed methodology works on extracting a two equal roots/factors of the specific energy and specific force expressions, where the two equal roots/factors yield the critical flow depth. The methodology is illustrated for trapezoidal, rectangular, triangular, and parabolic channels.
