马斯京根法(以下简称M法)是一种基于槽蓄方程和水量平衡方程的河道流量演算法。由于使用方便,精度也较高,在生产实践中得到了广泛的应用。在方法上,由整河段演算发展到了分河段连续演算;在理论上,成功地证明了M法演算方程系为对流扩散方程具有二阶精度的差分格式。从而使M法有了坚实的水力学基础,同时也使M法参数K和x有了明确的物理意义。由此可知,M法线性演算不过是对 Muskingum method (hereinafter referred to as M method) is based on the tank storage equation and water balance equation of the river flow algorithm. As easy to use, high precision, in production practice has been widely used. In the method, the continuous river section calculation is developed from the whole river section calculation. In theory, the differential equation with the second-order accuracy of the M method is successfully proved to be the convection-diffusion equation. M law has a solid foundation of hydraulics, but also make the M law parameters K and x have a clear physical meaning. From this we can see, M method linear calculus is just right
