| 摘 要： | 本文利用地面水流运动的零惯量模型，对波涌灌水流运动的全过程进行了数学模拟，利用一阶隐式差分公式求解零惯量水流运动方程，得出了进水和退水距离与时间的变化关系曲线，与大田实测波涌灌资料进行了对比，一致性较好。

| Abstract: | In this paper the zero-inertia mathematical model for surface now is utilized to simulate the whole process of the flow in surge irrigation. The flow equations are solved by using first order latent difference equation.The relationship between the time and distance both in advance and recession phases are obtained. The results agree with the field test fairly well. |
