A modification to the White, Bettess and Paris Analytical Regime Approach

AbstractThe shape of the cross section of a self formed channel is one of the most important issues in river engineering and irrigation canal design. Several methods have been proposed for the shape of stable channel. The analytical approach to river regime of White et al. (1982) has been analyzed and modified in order to obtain a stable cross section geometry more similar to that observed in field and laboratory tests. To this aim, the original trapezoidal cross section has been changed, employing the analytical geometry for stable channel proposed by Huang et al. (2005). The modified White et al. approach shows good agreement with recent laboratory tests on stable non-cohesive straight channels
