This is the analytical study on the unsteady open channel flow including the flood and the long wave motion. The analytical method used in this paper is the linearization of the equation of unsteady flow for the operational mathematics. Many scientists have studied this problem by the other theoretical methods, but this paper is the special study that shows the wave height concerning the Manning's n and the momentum coefficients α, η and the wave velocity concerning α, η not n. Furthermore we show the critical Froude number is 1/√<α>. We take up the initial conditions υ(l, 0)=0,ξ(l, 0)=0 and the boundary conditions υ(0,θ)=υ(0,θ) ξ(0,θ)=ξ(0,θ), so that many cases of the unsteady flow is solved.
