Reservoir Project

The “Yangtze River to Huaihe River” project is another large-scale trans-basin water diversion project in China, following the South-to-North Water Division Project. The reservoir project is in the period of China’s rapid development of modernization, informatization and marketization. During this period, reservoir-induced migrants have great differences in resource endowment and development opportunities, so they show different characteristics in the integration process. In order to clarify these characteristics and formulate corresponding policies based on these characteristics to help them integrate into the society of the resettlement area as soon as possible, this paper has completed two aspects of work: First, a method for identifying social integration is proposed. Second, the characteristics of social integration of different migrant groups in different time dimensions are analyzed. This study has two important findings: First, the extent of information sources and understanding of policies has a greater impact on the social integration of migrants. The wider the source of information and the more understanding of policies, the more it helps migrants to integrate into society. Second, the social network relationship established by the female migrant group in the maintenance activities will greatly promote their social integration.

With the rapid development of China, water pollution is still a serious problem despite implementation of control measures. Reasonable water environment management measures are very important for improving water quality and controlling eutrophication. In this study, the coupled models of hydrodynamics, water quality, and eutrophication were used to predict artificial Playground Lake water quality in the Zhenjiang, China. Recommended “unilateral” and “bilateral” river numerical models were constructed to simulate the water quality in the Playground Lake without or with water diversion by pump, sluice and push pump. Under “unilateral” and “bilateral” river layouts, total nitrogen and total phosphorus meet the landscape water requirement through water diversion. Tourist season in spring and summer and its suitable temperature result in heavier eutrophication, while winter is lighter. Under pumping condition, water quality and eutrophication of “unilateral” river is better than “bilateral” rivers. Under sluice diversion, the central landscape lake of “unilateral river” is not smooth, and water quality and eutrophication is inferior to the “bilateral”. When the water level exceeds the flood control level (4.1 m), priority 1 is launched to discharge water from the Playground Lake. During operation of playground, when water level is less than the minimum level (3.3 m), priority 2 is turned on for pumping diversion or sluice diversion to Playground Lake. After opening the Yangtze river diversion channel sluice, priority 3 is launched for sluice diversion to the Playground Lake. When the temperature is less than 15 °C, from 15 °C to 25 °C and higher than 25 °C, the water quality can be maintained for 15 days, 10 days and 7 days, respectively. Corresponding to the conditions of different priority levels, reasonable choices of scheduling measures under different conditions to improve the water quality and control eutrophication of the Playground Lake. This article is relevant for the environmental management of the artificial Playground Lake, and similar lakes elsewhere.

For projects, especially large-scale projects, due to the long time of project construction, the construction of the complexity of the geological conditions, sometimes inevitably lead to quality defects.How scientific and reasonable quality defects hidden works to take remedial measures, or effective correction to restore the loss of time, cost, quality, safety,become an important engineering problem.Some cracks, will not have a substantial impact on the project, you can take measures to deal with to ensure proper implementation of the project.The article takes the analysis of crack initiation and Treatment in the Suining two station project.There are a lot of reference in processing defects in the country's large projects.Statistical indicators from the implementation of the results, analysis shows that to achieve even better than the regulatory requirements, and achieved the expected results.

Purpose The purpose of this paper is to aim mainly at social public decision-making problems, studies the corresponding relationship between different voting rule combinations and the final results, and discusses the quantitative relationships between group intelligence (final votes) and individual intelligence (everyone) to defend democracy under the circumstance of rapid development of network technology, and crowd intelligence becomes more complicated and universal. Design/methodology/approach After summarizing the crowd co-decisions of related studies, the standards, frameworks, techniques, methods and tools have been discussed according to the characteristics of large-scale simulations. Findings The contributions of this paper will be useful for both academics and practitioners for formulating VV&A in large-scale simulations. Originality/value This paper will help researchers solve the social public decision-making problems in large-scale simulations.

A one-dimensional numerical model was developed for unsteady-flow in a large-scale conveyance channel with complex inner boundary conditions. Using Taylor expansion and finite difference method, this model incorporated three types of inner boundary conditions, including regulators, inverted siphons, and flumes with parallel connections. It can facilitate continuous simulation with large-amplitude variations in water level and flow discharge during the flow transitions. Transition flows were simulated by this model, which were caused by the operation of a single gate of the Middle Route of the South-to-North Water Diversion Project. The discharges of simulation were consistent with the discharges of formulas calculation, and the water level variations accords with hydraulic law. The results indicate its efficiency and applicability on simulating hydraulic response of large-scale conveyance channels with complex inner boundary conditions.

The central region of China boasts a long history, abundant resources, convenient transportation, advanced economy, a strong industrial and agricultural foundation and a rapid development of modern service industry, with about 10.7% of the country's total land area, 26.5% of the country's population and a GDP of about 21.4% of the country's total . As the population center, transportation hub, economic hinterland and important market, it is the second echelon of China's economic development; the central region of China plays an important role in the division of labor in China. The middle reaches of the Yangtze River water network includes four neighboring provinces- Hubei, Hunan, Anhui and Jiangxi. Although all four provinces are located in the middle of the Yangtze River Basin, there are still quite some differences. Based on the 2017 Statistical Yearbook data, this paper studies the economic supportive index of pig breeding in four provinces located in the water network area of the middle reaches of the Yangtze River in Jiangxi, Hubei, Hunan and Anhui. The evaluation results show that among the four provinces, the socio-economic conditions of Hubei Province can most support the large-scale cultivation of live pigs, and the support of Jiangxi Province is the weakest.

The South-to-North Water Diversion Eastern Route Project of China is a complex large scale system. It is important of constructing a modelling and simulation for this type of system. This paper proposes a modelling and simulation technique for large scale water project based on Agent calculation and complex adaptive system (CAS). The simulation experiment system, about multi-Agents of water resources in East CAS management features is conducted using SWARM. We demonstrate also the interaction within all kinds of objects and the behaviour of system evolvement in the course of water resources allocation and scheduling. The simulation results show the proposed simulation model effective.
