摘　　要：介绍了水力学模型及其数值计算的概念,水力学基本控制方程,讨论了观测实验、理论分析和数值模拟等水力学应用问题的研究方法,阐述了有限差分法、有限元法、有限体积法、有限分析法等数值离散方法的优缺点,对其在水力学数值模拟计算中的优劣性和适用范围进行了比较分析.This paper introduces the concept of hydraulics model, its numerical calculation and the hydraulics basic control equation. Observation experiment, theoretical analysis and numerical simulation are discussed such as hydraulics research methods of applied problems. It expounds the advantages and disadvantages of numerical discrete method such as the finite difference method, finite element method, finite volume method, finite analysis method. The superiority and inferiority in the hydraulic numerical simulation and its applicable scope are comparatively analyzed.
