Abstract:

The South-to-North Water Transfer Project is a cross century water diversion project. So it is very important to ensure its normal operation. The hydraulic calculation of Jiping Canal of the South-to-North Water Transfer Project is carried out in this paper, working out cross section, the profile and the X-Y-Z perspective plot of Jiping Canal respectively. An analysis of the canal stability enables us to get the condition in which the canal is stable, which will provide strong technical support for the design and construction of the canal. Therefore, the analysis has important practical significance. The study will be effective guidance on the normal operation of Jiping Canal of South-to-North Water Transfer Project.

Abstract:

North China faces severe water scarcity—more than 40% of the annual renewable water resources are abstracted for human use. Nevertheless, nearly 10% of the water used in agriculture is employed in producing food exported to south China. To compensate for this ‘virtual water flow’ and to reduce water scarcity in the north, the huge south–north Water Transfer Project is currently being implemented. This paradox—the transfer of huge volumes of water from the water-rich south to the water-poor north versus transfer of substantial volumes of food from the food-sufficient north to the food-deficit south—is receiving increased attention, but the research in this field has not yet reached further than rough estimation and qualitative description. The aim of this paper is to review and quantify the volumes of virtual water flows between the regions in China and to put them in the context of water availability per region. The analysis shows that north China annually exports about 52 billion m 3 of water in virtual form to south China, which is more than the maximum proposed water transfer volume along the three routes of the Water Transfer Project from south to north.

Abstract:

The availability of and demand for water in China is an extreme case of uneven distribution in time and space. In response, the South to North Water Diversion (SNWD) project, the largest inter-basin water transfer scheme in the world, channels large amounts of fresh water from the Yangtze River in southern China to the more arid and industrialised north. In order to keep the SNWD project running smoothly, a comprehensive governance system has been implemented and innovative institutional arrangements have been created to facilitate the transfer of water itself. By taking the SNWD project’s Middle Route as one case study and drawing on primary and secondary data, this article examines the project’s emerging institutional arrangements. The article outlines the establishment of new institutions for the SNWD project with high administrative rankings at both central and local levels, the encouragement of inter-department cooperation, the adoption of a market mechanism and the integration of market functions into administrative functions. We argue that these institutional arrangements have to some extent overcome common challenges in water governance in China, including an engineering-heavy approach and what Chinese commentators have traditionally called the problem of water being managed by multiple government ministries and municipal authorities as the common metaphor of ‘nine dragons managing the water’. Our findings have significant implications for understanding the continuing evolution of water governance in China.

Abstract:

The South-North Water Transfer Project (SNWTP), if fully developed, could divert 40-50 km3/yr from the Yangtse basin to the North China plain, alleviating water scarcity for 300-325M people living in what even then will be a highly water-stressed region. Construction of the next stage, diverting up to 20 km3 at a cost of about $17,000M (including $7000M in ancillary costs), is to start in 2002/3. A recent World Bank study suggests that the project is economically attractive. This conclusion has been disputed by the World Wildlife Fund (now the Worldwide Fund for Nature). This paper concludes that little confidence can be placed in either of these analyses. It therefore seeks to throw light on how the project fits within a broader regional and agricultural development setting. The project is hugely expensive, and would at the margin tend to preserve water in low value agriculture and require the resettlement of upwards of 300,000 people. On the other hand, the pace and scale of socio-economic change in China are without precedent, and adjustment problems on the North China plain are greatly exacerbated by water scarcity. Reallocation of water from irrigation to municipal and industrial uses or to the environment is socially divisive and in some instances physically impracticable. The transfer project would greatly alleviate these difficulties. It is these arguments (which are ultimately political and pragmatic), rather than those based strictly on economic or food security concerns, that make the Government's decision to proceed with the project fully understandable.

Abstract:

Water quality assurance is the primary factor for the successful operation of water diversion projects across river basins. The rapid prediction of water pollution is the basis for timely and effective emergency control and disposal measures. In China, since the open channels intersect with numerous waterways and traffic arteries, water transfer projects are prone to sudden water pollution accidents. In this paper, the rapid prediction method was developed for sudden water pollution accidents that possibly occurred in the East Route of the South-to-North Water Diversion Project (ERP) in Shandong Province. With the empirical formula of the pollution transfer law, a rapid prediction model of water quality (WQRP) was established based on the simulation of the typical accidents in the main channel. Finally, four typical accidents were selected as application examples, and the prediction results were compared with the results from a computer numerical simulation to demonstrate the validity of the model. The results showed that the prediction results by the WQRP model meet the accuracy requirements. This method is of great significance for providing water transport security in the extreme conditions of long-distance water transfer projects.

Abstract:

Abstract This article investigates the energy intensity and related impacts of the Eastern Route of China's South-North Water Transfer Project, based on the concept of the water–energy nexus. It finds that from November 2013 to May 2017 a total of 2.35 billion kWh of energy was consumed to transfer 15.5 billion m3 water driven by a large-scale system of pumping stations. This energy production required 7.4 million m3 of virtual water and emitted 1.93 MtCO2e of carbon. An average water–energy nexus ratio of 0.05% indicates that transferring 100 m3 of water consumes 0.05 m3 of virtual water due to the electricity consumption of the Eastern Route's pumping stations. It is estimated that to transfer 7.3 billion m3 water by 2030, this mega project will consume 1.35 billion kWh of energy, 4.6 million m3 of virtual water and emit 0.94 MtCO2e of carbon. These findings and scenario analysis demonstrate that strategies are needed for mitigating the energy intensity of the Eastern Route, such as improved pumping efficiency, reduced water loss during water delivery, decreased water quotas, and promotion of other, less carbon-intensive water sources in destination provinces.

Abstract:

Abstract Public participation in water conservation projects is gaining more and more attention in the information era. Public opinion, showing the focus and interests of the public, is the basis of public participation. This paper proposes a social sensing system based on social media platforms, which employs two natural language processing technologies, namely, sentiment analysis and topic modeling. The public opinion on water conservation projects is monitored from three perspectives: public opinion intensity (POI) monitoring, topic detection, and sentiment analysis. To test their effectiveness, a case study on the South-to-North Water Transfer Project (SNWTP) in China is conducted. The public opinion data were acquired from Sina Weibo, China's largest social media platform. The results indicate that: (1) POI peaks when hot project-related events occur, and POI of direct stakeholders apparently exceeds indirect stakeholders; (2) different stakeholders have different topics of concern closely associated with their interests; (3) negative events always lead to dramatic decreases in the sentiment value (SV), while positive events only slightly lift SV. The proposed system has achieved real-time monitoring of the public opinion on water conservation projects. Consequently, it can help to improve the level of public participation and provide a valuable reference in project management and policy-making.

Abstract:

An inter-basin water transfer project is one of the effective ways to resolve the problem of an uneven distribution of water resources. Temporal and spatial variations in rainfall in different basins greatly affect water supply and demand in inter-basin water transfer projects, leading to risks to the operation of the water transfer projects. This paper applies a Bayesian network model to analyze this risk and studies the rich–poor rainfall encounter risk between a water source area and water receiving areas in the middle route of the South-to-North Water Transfer Project in China. Real time scenario simulations with the input of new observations were also studied. The results show that the rich–poor rainfall encounter risk is high for the Tangbai River receiving area in the fourth quarter, for the Huai River and South of Hai River receiving area in the second quarter, and for the North of the Hai River receiving area in the fourth and first quarters. The scenario simulations reflect risk change in the operation of water transfer projects, providing scientific decision support for the management of the water resource distribution in the inter-basin water transfer projects.

Abstract:

The South-North Water Transfer Project is playing a more and more important role in ensuring economic and social development and maintaining a good ecological environment for north of China. However, long-term over-exploitation of groundwater has caused a series of ecological and environmental problems. The first phase of the South-to-North Water Transfer Project was successfully passed through in 2013 and 2014. The water supplied by this huge project provided critical water source for implementing groundwater overexploitation control. In order to promote the management and protection of groundwater resources, the overdraft areas had adopted comprehensive measures to reduce groundwater extraction, such as accelerating the construction of supporting projects, shutting down groundwater mining wells, improving the groundwater monitoring station network, and reforming the water resources fees and so on. The urban groundwater overexploitation control work has received good progress. Based on the investigation and statistics of groundwater overexploitation control in the water receiving region of the first phase of the South-North Water Transfer Project, it was found that since the first phase of the South-to-North Water Transfer Project passing though, the water groundwater withdrawal decreased by 15.23×108 m3 by making full use of the water from the South-North Water Transfer Project, including 2.36×108 m3 in Beijing, 0.67×108 m3 in Tianjin, 6.39×108 m3 in Hebei, 3.84×108 m3 in Henan, 1.62×108 m3 in Shandong, and 0.35×108 m3 in Jiangsu, respectively. The number of groundwater withdrawal wells closed was 15202, including 331 wells in Beijing, 582 in Tianjin, 4895 in Hebei, 6213 in Henan, 2012 in Shandong, and 1169 eyes in Jiangsu, respectively. In terms of groundwater level, the trend of continuous decline in groundwater level has been effectively curbed in most areas of the water receiving region, however, in some areas the groundwater level is still declining due to the too large cumulative over-exploitation of groundwater. Shijiazhuang City was selected as typical monitoring site to explain the groundwater overexploitation control effect on groundwater level. The analysis of the monitoring data of typical monitoring sites showed that groundwater overexploitation control has a great influence on the groundwater level change in Shijiazhuang urban area. This study also puts forward some problems and suggestions in promoting the groundwater overexploitation control in the water receiving region, and provides reference for the construction of ecological civilization and national water security.

Abstract:

The South-to-North Water Transfer Project plays an important role in guaranteeing the sustainable development of economy and society in North China. The first phase of the middle route of the South-to- North Water Transfer Project (m-SNWTP) has been running safely in the past three years, and the dispatched water amount is increasing. This paper mainly describes the water operation of the m-SNWTP and the groundwater protection in the water-receiving areas. Up to the end of June 2018, more than 1.4×1010m3water had been supplied to the m-SNWTP benefited regions, including 8.65×108m3environmental water. In addition, the m-SNWTP provides water source guarantee for the environment restoration. Over 1.326 ×109m3overexploited groundwater has been reduced in the urban areas of the water-receiving areas, and the continuous decline of groundwater level has been effectively curbed.

Abstract:

The cracking control standard of water delivery structure is quite strict especially for middle-route of south-to-north water transfer project with long distance water transfer, large discharge, the crack prevention standard is extraordinary strict and must be reached. Early crack during construction period will affect safe operation of aqueduct, and diurnal variation of air temperature has significant effect on temperature field of thin-walled structure. Construction process simulation and temperature filed calculation during construction period about Caohe river landing rectangle aqueduct of Beijing-Shijiazhuang emergency water supply engineering of middle-route of south-to-north water transfer project are carried out by FEM , and compared with the monitoring temperature. The comparison result shows that temperature field during construction can be accurately simulated by calculation, which is helpful for guiding construction and choosing construction scheme, and worthy to popularize to other similar projects. From the calculation and monitoring, the maximum temperature difference is less than the standard, so there will be no serous cracks during construction in Caohe river aqueduct.

Abstract:

The Eastern Route of the South-to-North Water Diversion Project is a national strategic measure to improve the water supply conditions of the cities along the route, Jiaodong and Huaibei regions. However, the Water Diversion Project not only brings social and economic benefits, but also changes the hydrological situation and ecological environment of water source area, transfer area and receiving area. In this paper, Dongping Lake is selected as the research object. By using the analytic hierarchy process and fuzzy evaluation method, the index system of the impact assessment of the Eastern route project on the water environment of Dongping Lake is constructed, and a multi-level fuzzy evaluation model is established to conduct quantitative and qualitative research on the impacts of hydrology, meteorology, water ecological environment, soil and other aspects as well as ecological and economic compensation. The analysis results show that the operation of the Eastern route project has brought some negative effects on Dongping Lake, mainly reflected in the aspects of soil, ecological compensation, hydrology and meteorology, and the negative effects on the water ecological environment are light. By studying the impact of the Eastern route project on the water environment of Dongping Lake, this paper aims to improve the environmental impact assessment system for the water receiving area of the Eastern Route of the South-to-North Water Diversion Project, and to provide reference for the research on the environmental impact assessment system for other water diversion projects in China.

Abstract:

The South-to-North Water Transfer Project (SNWTP) in China is a considerable trans-basin water transfer project which can relieve the serious water resources shortage in northern of China and optimize water resources allocation. The construction of SNWTP has strategic importance to transfer the water from south to north and realize the target of water resources allocation. The operational management risks of SNWTP are discussed in this paper and the eastern route of SNWTP is studied as a case. The definition and connotation is given on the risk of operational management of SNWTP and the operational risk factors of SNWTP are distinguished. The index system of operational management risks is established. Considering the uncertainty of the risks of SNWTP, the risk evaluation model based on evidence theory is put forward. The countermeasures for the operational management risks of eastern route of SNWTP is brought up from the aspects of establishing risks management organization, risks management platform and emergency mechanism, technical methods and so on.

Abstract:

The inter-basin water transfer project is one of the most important means to solve the uneven distribution of water resources in time and space, rationally allocate water resources, and promote the construction of water ecological civilization. Research on the operation impact and channel hydraulic response is meaning for the safe operation of long-distance water conveyance canals. Taking the Middle Route Project (MRP) of South-to-North Water Diversion (SNWD) as example, this paper built the onedimensional steady and unsteady flow model and investigated the impact of roughness change, emergency rescue technology and equipment, and sluice control failure. Results showed that increased roughness decreased the water diversion efficiency of MRP to some degree. The emergency rescue technology and equipment occupied the channel section and declined flow capacity. The occurrence of sluice control failure relatively played an increasing impact on upstream water level and a decreasing impact downstream water level and flow discharge. The impact of the above scenarios on the scheduling operation can be reduced to a certain extent by regular cleaning and maintenance, development of rational water emergency rescue project, development of staff skill, etc. This research can provide support for safe operation and regulation of the MRP of SNWD.

Abstract:

Jack-up technology is widely used in aqueduct reconstruction projects. In this paper, a self-developed displacement synchronous automatic control jack-up technology is introduced for the upgrading and reconstruction project of super large aqueduct in South-to-North Water Diversion Project. A new large span aqueduct jack-up construction technology is proposed and studied, and the key technologies of different heights of the aqueduct are discussed. During the jack-up reconstruction of the Lihe Aqueduct from Taocha Canal Head to Shahenan Canal Project in the first phase of the middle route of the South-to-North Water Transfer Project, the overall synchronous lifting of the aqueduct body was achieved by 72 cm, and then the aqueduct body was dropped proportionally. Finally, the jack-up reconstruction of the entrance section of the Lihe Aqueduct was achieved by 50 cm, and the exit section was not jack-up, and the middle section showed a linear change. The research results have a certain reference value for the reconstruction projects of similar structures with different heights at both ends.

Abstract:

In order to meet the demand of emergency water supply in the northern region without affecting normal water transfer, considering the use of the existing South-to-North Water Transfer eastern route project to explore the potential of floodwater resource utilization in the flood season of Hongze Lake and Luoma Lake in Jiangsu Province, this paper carried out relevant optimal operating research. First, the hydraulic linkages between the lakes were generalized, then the water resources allocation mode and the scale of existing projects were clarified. After that, the actual available amount of flood resources in the lakes was evaluated. The average annual available floodwater resources in 2003–2017 was 1.49 billion m3, and the maximum available capacity was 30.84 billion m3. Then, using the floodwater resource utilization method of multi period flood limited water levels, the research period was divided into the main flood season (15 July to 15 August) and the later flood season (16 August to 10 September, 11 September to 30 September) by the Systematic Clustering Analysis method. After the flood control calculation, the limited water level of Hongze Lake in the later flood season can be raised from 12.5 m to 13.0 m, and the capacity of reservoir storage can increase to 696 million m3. The limited water level of Luoma Lake can be raised from 22.5 m to 23.0 m (16 August to 10 September), 23.5 m (11 September to 30 September), and the capacity of reservoir storage can increase from 150 to 300 million m3. Finally, establishing the floodwater resource optimization model of the lake group with the goals of maximizing the floodwater transfer amount and minimizing the flood control risk rate, the optimal water allocation scheme is obtained through the optimization algorithm.

Abstract:

Based on the theory of ecological hydraulic radius model (EHRM) for estimating watercourse ecological water requirement, the in-stream ecological water requirement for satisfying fish habitat in watercourse is calculated by using the example of Daofu hydrological station in Xianshuihe River at the Western Route First Stage Project of China’s South-to-North Water Transfer Scheme. Meanwhile, in order to check up practicability of this new model, the calculated result is compared with that of Tennant method. The result shows that the watercourse ecological water requirement calculated by EHRM is basic between the minimum ecological water required and condign ecological water requirement calculated by Tennant method. Because of more information of flow velocity for satisfying fish habitat taken into account, the ecological water required calculated by EHRM is more accord with the real instance of Xianshuihe River at the Western Route First Stage Project of China’s South-to-North Water Transfer Scheme. The in-stream ecological flow of every year is less than that of 40%per annual averaged flow during 1965 -1987, the range of percent is 12.0%-33.2%. If the flow is regulated by the calculated by EHRM after the Western Route First Stage Project of China’s South-to-North Water Transfer Scheme will be run, the watercourse ecosystem will be in better function state.

Abstract:

Scientific and effective operation control of the Middle Route of South-to-North Water Diversion Project (MRP) is crucial to ensure water conveyance safety. As the longest water transfer project in China, its operation is confronted with unprecedented difficulties since it is controlled by a large number of check gates and diversion gates, subject to multiple constraints, and has no online regulation reservoirs. No automatic control models have been successfully put into use yet. This paper firstly introduced an expanded downstream depth operation method, and then scheduled the delivery using the volume balance principle and chartography according to the possible combination of flow change of the check gate, water volume change of the pool and flow change of diversions. Next, an improved real-time control model was established on the basis of PI controller, and the models were integrated into an automatic system for daily operation. Finally, a case study was carried out. Results showed that water level variations could be controlled within the target interval (0.25 m), and users’ demands could be met five times more rapidly. In addition, the total times of check gate operation could be reduced almost two times. The findings could promote the intelligent operation of the MRP.

Abstract:

In order to solve the prewarning problem of South-to-North Water Transfer Project safety, an intelligent cooperative prewarning method based on machine learning was proposed under the framework of intelligent information processing. Driven by the monitoring data of the South-to-North Water Transfer Project, the single sensor in typical scenes was studied, and the security threshold was predicted along the vertical axis of time, firstly. With the support of the data correlation calculation, the sensors in the typical scene were intelligently grouped, and the study objectives were changed into sensor grouping, secondly. Then, the nonlinear regression model between the single sensor and the multisensors was built on the time cross section, and the model was used to dynamically calculate the safety threshold of the current sensor for the second time. Finally, in the framework of intelligent information processing, a double verification mechanism was proposed to support the construction of the intelligent prewarning method for the safety of South-to-North Water Transfer Project. The paper collected the monitoring data from November 2015 to September 2016 in the typical scenarios. The experimental results showed that the methods constructed in the paper can be able to identify the abnormal causes of data sudden jump effectively and give the different level prewarning. The method provides a strong theoretical support for further manual investigation work.

Abstract:

The safety of water delivery and water quality in the South to North Water Transfer Project of China is important to northern China. Water quality data, flow data and data on factors that influence water quality were collected from 25 May to 26 August, 2013. These data were used to forecast water quality and calculate the relative error when using a genetic algorithm optimized general regression neural network (GA-GRNN) model as well as conventional general regression neural network (GRNN) and genetic algorithm optimized back propagation (GA-BP) models. The GA-GRNN method requires few network parameters and has good network stability, a high learning speed and strong approximation ability. The overall forecasted result of GA-GRNN is the best of three models, of which the root mean square error (RMSE) of every index is nearly the least among three models. The results reveal that the GA-GRNN model is efficient for water quality prediction under normal conditions and it can be used to ensure the security of water delivery and water quality in the South to North Water Transfer Project.
