River Training Measures To Optimize The Characteristics Of The River Hydrology Of Shaying River

Shaying River is the longest tributary of the upper reaches of Huaihe, the Huaihe traffic supply has significant effects on hydrological processes, the greatest impact in Huaihe. The river is the Huang Huai plain on the important water source, nourishes the coast honest kind of Yuwan village. In recent years, as a result of unreasonable human activities such as industrial and agricultural sustained effects, deterioration of water quality, air pollution, garbage pollution, the environmental problems become increasingly serious. Shaying River is densely populated, the environment problem is particularly prominent.Facing more and more serious disaster, the people of the area of Shaying River have increasingly taken measures, implementation of diversified management measures, such as engineering control measures, biological measures and non engineering measures. In this paper the Shaying river management measures, through to the Shayinghe river hydrological characteristic change before and after management situation analysis, and according to the hydrological characteristics of the change of coastal area daily production and life impact are analyzed, finally the river harnessing measures the rationality of evaluation, and puts forward the improvement of the existing river control measures.This paper choose the river hydrological features elements of the three:the river flow, river sediment concentration and water quality, these three elements can be better reflected the river hydrological regime change. This article mainly adopts the analogy method, in the same element phase conditions, will present status and the previous average of contrast. The first method is in river flow rate under the condition of same contrast in recent years, the water level value between 1951 and2000the average level, and then draws the Shayinghe river section of hair structure, through contrast found in section of sediment deposition is not obvious, the river management measures changed the river’s water environment is the result the main cause of the rise in the river level; the second kind of method is to set the same level condition, in contrast to recent years river flow changes, by contrast, Shayinghe river flow large inter-annual changes, areas along the river management activities is an important influence factor. River sediment concentration research is based on the river flow and sediment discharge of the river contrast, average sediment concentration, and analysis of river sediment concentration of interannual variation, and to explore the river sediment concentration change causes, finally find out the measures of reducing river sediment concentration. Quality problem is always the Shaying River paper is important, because the region is densely populated, once the environmental problems, the consequences are unthinkable, taking Fuyang station measured hydrologic data as the basis, to the existing national water quality assessment standard, adopt the method of fuzzy mathematics, to determine the Shaying River each the main sections of the river water quality, and then put forward the optimization measures for river water quality.After the Shaying River, sediment, water quality analysis, can be obtained from existing channel management measures function as follows:Shayinghe river flow:through data analysis and comparison, we can see that the river flows are seasonal and interannual variation reduction, reservoir, flood storage area and river engineering control measures function should be played, but separate river water and water environment association. Through the ecological management model, an improvement of this feature.Shayinghe river sediment concentration:through the analysis of data, can see the Shaying river sediment in recent years has increased, mainly due to the unreasonable construction and excessive due to agricultural activities, can be related through optimization measures to reduce soil and water loss, and reduce the silt content of river.Shayinghe river water quality:Based on the data of water quality comparison, can be seen in recent years Shaying River water pollution is very serious, this is mainly due to the local social and economic development and problems arising in the process of industrial and agricultural pollution, excessive lead, which can be based on the corresponding biological measures to alleviate the problems of water pollution.Finally, according to the hydrological elements of the analysis results, to evaluate the rationality of river management measures, and points out the related optimization measures.
