查询词典 Volga River

Band on analysis of the river system and its formation, some characteristics of the river system are expounded herein such as fluidness, green ecology, resources, hydraulic, adjustability, human culture, integrity and so on. Functions of the river system is given such as natural function, service function, humanities and landscape function and disaster characteristics.

通过分析河流系统的概念和考虑河流系统组成特点，详细地论述了河流系统的流动性、绿色生态、资源性、水能、可调控性、人文性、完整统一性等；系统地提出了河流功能的具体内容，包括自然功能、服务功能、人文景观功能和灾害性能。

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。

The results show that:(1) the overall water quality in the Xiangjiang River had become worse during the 1990s and the main pollutants which caused aggravating pollution were total coliforms, total phosphorus, petroleum and total hydrargyrum ;(2) the main pollution sources were living pollution, which increased evidently in recent years, and industry pollution, of which heavy metal pollution is evident;(3) among the mainstream of the Xiangjiang River , river sections in Zhuzhou, Xiangtan and Changsha suffered from the most serious pollution;(4) it is forecasted that living pollution and agriculture pollution will become more serious in the future.

结果表明：湘江总体水质在20世纪90年代呈恶化趋势，致使污染加剧的主要因子是总大肠菌群、总磷、石油类和总汞；主要污染源为工业污染和生活废水污染，近年来生活废水污染日益突出，工业污染中重金属污染明显；在干流不同河段中，株洲、湘潭和长沙河段污染最为严重；估计未来湘江的生活污染和农业污染还会加剧。

In the paper, river and the downstream area of dike are regarded as a whole system, and hydraulic model of coupling 1-D river and gradual dike-break is established, therein the Preissmann implicit difference scheme is applied to Main River, and the FVM is applied to the breach and polder. On the basis of FVM and unstructured grids, TVD ?

本文将河道与堤坝下游区域视为一个整体，对于单一河道采用Preissmann四点隐式差分格式计算，对于溃口及圩区采用有限体积法，建立了一维河道与堤坝渐溃耦联的水力模型，也是一维、二维耦合的水流模型。

From the Yellow River flows through the water from the upper reaches of the Chuan Zhen, a singular landscape, steep terrain, the big blue sky and white clouds Gap 50 at various tourist attractions, from not more than 3 Wa Lane, 10 minutes Wudang God, Lei Zu Feng Yun, Gu Du Okawa 3 with a long history The human landscape; water of the Yellow River has been surrounded on all sides of the Yellow River Island rabbit unique natural landscape of lakes and reed ten fishing grounds.
