【 摘 要 】

In this study, the water surface elevations in gradually varied flows are calculated by Differential Quadrature Method (DQM) which is recently used in Hydraulics Engineering. Water surface profiles can be calculated by solving the systems of equations that are linear at uniform channel, nonlinear at non-uniform channel. A uniform channel is selected as on illustrative example. The obtained results are compared with those of Direct Step Method. Gradually varied flow is calculated for M and S profiles in a trapezoidal channel. The differences between the results are negligibly small.
