Abstract

The bottom width of channels carrying spatially varied flow with increasing discharge is usually flared in the flow direction. This produces a non‐prismatic section. This paper, based on the law of linear momentum conservation, presents a new form of the governing dynamic equation for flow in such circumstances. In addition to the computed water surface profile, the proposed equation affects the position of the control section and its flow depth as well. Copyright © 2002 John Wiley & Sons, Ltd.

## Abstract A new governing equation was proposed for the spatially varied flows with increasing discharge, which affects the position and the depth of the control section as well as the entire water surface profile within the channel. This paper presents the use of the Newton‐Raphson method in the
