| 摘 要： | 本文应用有限元法求解地表径流的运动波方程,模拟了陕北子州岔巴沟流域内径流实验场的天然降雨的坡面漫流过程,效果尚好。这表明,有限元法是求解地表径流物理模型的可行方法。文中还分析了此模型在基本假定上的欠缺以及用于实际预报尚待解决的问题。

| Abstract: | The finite element method is used to solve the kinematic wave equations of surface runoff. Then, the procedure is applied to simulate the overland flow processes produced by natural rainfall on an infiltrating loess slope in Chabagou Basin, Shaanxi province. The results are satisfactory, which indicate that the finite element method is a feasible procedure for solving the mahematical models of surface hydrology. Some defects in the assumption of the model are analysed and problems when it is used in prediction are discussed. |
