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.
水力模型以描述河道洪水波运动的Saint-Venant方程组为基础，用Newton-Raphson方法直接求解按Preissmann加权四点格式进行离散所得的非线性代数方程组，提出了压缩存贮形式的Gauss列主元消去法并对数值解的收敛性进行了讨论；将支流流量的松弛迭代方法从树状河系推广到了环状河网，使任意复杂河网水力计算的问题都可化为一系列的单一河道的水力计算问题；建立了水力模型与水质模型的联接，初步应用于既有洪水、暴雨、强潮等综合影响，又存在多种水工建筑物及水力调度问题的大型复杂河网中的非恒定流水力、水质计算问题；利用MapInfo对计算结果的可视化进行了研究，有利于决策者快速、方便、准确地作出决策。

Due to the construction development and rebuilding of the old city in Linyi, though the city's flood-control and waterlog-drain system have been improved for several times, there are still many problems at present such as low standards, too many obstructive buildings in riverways and unmatched branch projects.
随着临沂城市建设的发展和旧城改造，城市防洪、排涝体系虽然经过几次治理，但临沂城现状防洪排涝体系仍普遍存在着标准低、河道阻水建筑物多、支流工程不配套等问题。

The reduction of sediment transported down the Mississippi River was the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffs, river-training structures, and bank revetments and soil erosion control programs in the areas drained by them.
夹带砂石量的减少是由于沿河地区建起了不少水利改造工程，例如密西西比河、密苏里河及俄亥俄河及其支流上的大坝修建、截弯取直工程、河道重塑、河岸护堤工程和水土流失防控工程。

badland：劣地
超细结构地区的河网密度,每平方公里内河道超过200公里,劣地(badland)就以这种河网密度著称. 河网(包括主流和全部支流)的几何排列样式,也就是流域内河流分布的空间轮廓. 水系型有许多种. 树枝状水系型其状如树,河网中的分支排列零乱,

creek：小溪
"西方自然地理学对河流分类有干流(Trunk Stream)、支流(Tributary)、溪流(Rill)、小河(Rivulet)、小涧(Brook)以及小溪(Creek)等名称,是按河流水量大小和河道长短而定.

Norton Sound：诺顿湾
1896年育空河支流克朗代克(Klondike)河上发现金矿,吸引来大批的拓居者. 当育空河流近白令海时,急转弯向北泄入诺顿湾(Norton Sound). 育空河三角洲宽64公里(40哩),布满湖泊和沼泽. 许多支流河道很浅,但是东北阿浦通口(Apoon Pass)曾通行船只.

surface runoff：地表径流
过去识别出的河谷网络似乎是地下河的杰作,但这些新发现的河谷却有些不同,它们的特征看似出自降雨、融雪或地表径流(surface runoff)的手笔. 比如,这些网络支流密布,从源头到末端,河谷的长度和宽度不断递增. 而且,河道的源头都分布在山脊顶部,

the Nile River：尼罗河
对尼罗河三角洲的地质勘探表明,公元前12世纪,尼罗河(The Nile River)的一段(支流)没水了,也许现在发现的"拉美西斯"古城原先是建在那段消失的支流边的,因为水干河道堵塞才拆迁到了塔尼斯,那么原来的古城到底建在那捏?
