A combined Gauss main-element elimination method with compress-storage technique is proposed, which with the characteristic of less-storage requirement, small rounding off and high stability, and solved the problem of large storage requirements in solving large linear algebraic equations in river networks hydraulics

提出了压缩存贮形式的Gauss列主元消去法，该方法具有存贮量小、舍入误差小、数值计算稳定的特点，在一定程度上解决了河网水力计算问题中关于众多线性方程组的存贮及其求解过程中可能面临的困难。

Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.
