Open-channel sections with constant kinematic wave parameters
The general mathematical behavior of the expressions used in analyzing the physical phenomena is of considerable importance in engineering practice. In current research, a nonlinear differential equation of second order to determine the cross sections in which the kinematic wave parameters are constant for a range of uniform flow depths is derived. By applying suitable boundary conditions, this equation is solved by Runge–Kutta method. In special cases, this equation is reduced to an analytical solution for the cross sections with constant hydraulic radius. Using this solution, the cross-section shape of the channel in which average flow velocity is constant for a range of uniform flow depths is derived. Reported herein are (a) cross sections with constant kinematic wave parameters and (b) cross sections with constant hydraulic radius.
