| 摘要: |
| 渠系非恒定流的数学处理目前尚无精确的解法。本文用数值方法对灌区渠系的水流运动要素进行了计算并与实测资料进行对比,认为直接差分方法和特征线方法可供渠系优化调控时使用。 |

| Abstract: |
| At present there is no accurate solution to mathematic processes to the unstady flow in canal, systems. The numerical method is used to calculate the key elements of kinetic flow in canal systems and also,comparison is made with the measured data in this paper. As a result,the direct difference method and the characteristic method can be expected to use in the optimal adjustment and control of canal systems. |
| Key words: unsteady flow, kinetic key element, initial condition, boundary condition, numerical method, |
