| A numerical computation of unsteady flow in the open channel was studied with the linearized four-point method of characteristics. A seiche test for this model was fulfilled and its result was very close to the exact solution. The effect of linearization to the accuracy of the result was small enough for the analysis of nearly horizontal flow, and this model would be applicable for the real unsteady flow problem because of its convenience. |
