从二维浅水非恒定流的控制方程出发，建立了一个二维湖泊流体动力学模型。
Based on the two-dimension adlittoral non-invariablenes flow control equation of lakes, a hydrodynamic model of lakes was built up.
对二维浅水方程粘性项给出了一个离散方案，并将其应用于求解后台阶流动问题。
We give a discretization method for the viscous terms of the two-dimensional shallow water equations , and the obtained discretized equations are used to solve the backward-facing step flow problem.
