Description
Summary:Triangular, parabolic rectangular and trapezoidal sections are practical open channel sections. For rectangular channel section it is possible to express the alternate depths analytically. For other sections the alternate depths are presently obtained by trial and error procedure. In this paper exact analytical solutions of alternate depths for exponential and trapezoidal open channel sections have been obtained in the form of fast converging infinite series and algebraic equations.
