Abstract With the development of economy and society, deep groundwater exploitation has intensified, even to the point of over-exploitation, resulting in multiple geological disasters. Thus, it is essential to regulate the deep groundwater table to a reasonable range. This paper selected the water intake area of the South-to-North Water Transfer Project in Tianjin as a case study. First, the groundwater flow and land subsidence model with MODFLOW-2005 and SUB Package were constructed. Second, the regulation schemes were designed based on the corresponding regulation principles. Lastly, the established groundwater model was adopted to forecast and simulate deep water table and land subsidence under different exploitation scenarios, and regulation effects were analyzed from the viewpoints of exploitation total amount, exploitation distribution, and exploited horizon. The results showed that groundwater tables of different layers and land subsidence were effectively controlled and improved under the three exploitation schemes for different planning level years. The exploitation total amount of groundwater, exploitation distribution, and exploited horizon had a direct impact on water table and land subsidence. From the perspective of regulating deep groundwater, all three schemes could achieve this goal, hence the three schemes were reasonable and feasible. The results are of great significance for rational utilization of deep groundwater.

The chosen water management mechanism will directly or indirectly determine the success or failure of the South-to-North Water Transfer Project. Due to the importance and complexity of the project and based on national conditions and the water situation, it is necessary to adopt a quasi-market mechanism. Using the advanced experience in China and abroad for reference, this study takes the central route of the project as an example and conducts experiments by undergraduates in the laboratory. Under the simplified experimental environment, three basic rules of a quasi-market mechanism are contained and integrated: the combination of governmental macro-control with a market mechanism; the combination of water-supply management with water-demand management; and the combination of routine management with emergency management. By observing the decision-making behaviour of the experimental participants, researchers constantly changed experimental conditions to simulate the real water market realistically; finally, researchers drew conclusions based on the repeated experiments.

Over Exploitation

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.

With regards to the characteristics of inter-basin water transfer projects, a 3d visual simulation (Three-Dimensional Visual Simulation, 3DVS) method for inter-basin water transfer project was proposed. A virtual reproduction of the entire project and its topography is achieved. The supplement of the three-dimensional topographic data was completed by Civil 3D combinedwith Google Earth. In this paper, the 3D digital model of inter-basin water transfer project is established using 3ds Max. Based on the established digital model, the simulation of channel water were realized .The Yuzhou section of South-to-North Water Transfer Project is taken as a case study. 3D visual simulation provides an effective way for the construction management and decision-making for inter-basin water diversion project.

The world famous South-to-North Water Transfer Project was built to alleviate serious water shortages in northern China. Considering that lake Hongze is an important freshwater lake in this region, analyzing the influence of water diversion on typical contaminant bioavailability and microbial abundance could aid in achieving a good overall understanding of hydrodynamic variation. Accordingly, in situ high-resolution measurements of diffusive gradients in thin films (DGT) and next-generation high-throughput sequencing were combined in order to survey Lake Hongze and determine the relationship between environmental factors and microbial communities. The DGT method effectively obtained more than the 85% of bioavailable concentrations of the corresponding contaminants; the results showed that labile P, S, Fe, As, and Hg concentrations were higher in areas influenced by water transfer. Moreover, the relative abundance and alpha diversity of the sampling sites distributed in the water transfer area differed significantly from other sites. The pH, conductivity, and labile Mn, As, and P were shown to be the primary environmental factors affecting the abundance and diversity of microbes. With the exception of bioturbation-affected sites controlled by labile Mn and pH, sites distributed in the water diversion area were most affected by As and conductivity, with little spatial discrepancy. Furthermore, site 2, with higher bioturbation abundance, and site 10, with stronger hydrodynamics, had low alpha diversity compared to the other sites. Consequently, the bioavailability of typical contaminants such as P, S, As, Hg, Fe, Mg, Cd, Pb, and Mn, as well as the diversity and abundance of microbial in the sites influenced by the water diversion, were significantly different to the other sites. Thus, the impacts of the South-to-North Water Transfer Project on participant lakes were non-negligible overall in the investigation.
