Theoretical Stable Hydraulic Section based on the Principle of Least Action

Abstract Despite decades of effort, stable hydraulic geometry for an open channel water flow has hardly been established because of too many unknown variables for too few rational relationships. This article derives the most efficient channel cross section using calculus of variations for the given...
