To examine the characteristics of unsteady open channel flow, one-dimensional depth-averaged velocity deformation model is developed. The fundamental form of streamwise velocity in a power series of depth is initially assumed, and the formula for friction velocity is derived. The coefficients of the power series are later evaluated by using the unsteady equation of motion. The applicability of the model is tested using experimental data. The numerical model showed reasonably good agreement with the experimental data. A new approach to reproduce the velocity deformation in the vicinity of free surface using the comparison of velocity distribution of numerical model and uniform velocity distribution of Engelund model is also presented.
