Study Results

Danjiangkou reservoir area is the main water source area and submerged area of the Middle Route South-to-North Water Transfer Project of China. Soil erosion is a significant influence factor in reservoir water quality and water transfer project success. The objective of this paper is to assess the soil erosion risk and mapping priority areas for controlling soil erosion of Danjiangkou reservoir area. The results indicated that the top three conservation priority levels cover almost all regions with severe erosion and prominent increase in erosion risk, with a total acreage of 3,531.543km2, accounting for 19.703% of the study area. These three levels to be managed as erosion control regions with appropriate conservation strategies in future projects. The study results will provide guidance in developing and implementing water conservation planning and to assist government agencies in decision-making for determining erosion control area, starting regulation project and making soil conservation measures.

The middle route of the south–north water transfer project (SNWTP) was built to relieve the pressure of increasing water demand in northern China. Serving as one of the major storage systems, optimal operation rules should be proposed promptly for Danjiangkou Reservoir, completed by a heightening project. In this paper, in order to seek out the optimal operation rules for Danjiangkou Reservoir, a multi-objective optimal operation model is developed, considering the inflow uncertainty, multi-year regulation cycle and water supply for the SNWTP. Three evaluation indexes (hydropower generation, water impoundment condition and shortage index) are adopted to assess the impacts of three influence factors (starting regulation level (SRL), inflow condition and flood control level) on Danjiangkou Reservoir operations. Finally, some critical operation strategies for Danjiangkou Reservoir are proposed. The results show that the optimal SRL for Danjiangkou Reservoir is 158 m and the recommended range of the water level at the end of the first year varies between 162–166 m (very wet), 164–166 m (wet), and 162–164 m (normal) on the basis of setting 158 m as the SRL.

Hydrosocial territories are produced not just through concrete water infrastructure, but through flows of people, water, money, and ideas at multiple scales. As part of China’s South–North Water Transfer Project, water drawn from the distant Danjiangkou Reservoir now supplies the megacities of Beijing and Tianjin with the majority of their drinking water. To provide this new service – supplying drinking water of sufficient quality and quantity – the Reservoir and its upper reaches are in the midst of socio-economic and ecological transformations. In this article, we outline the tools being mobilised to send a river of clean water north, including administrative interventions, displacement, and discursive imaginings. We argue that what is being attempted is a wholesale reorganisation that marginalises local territorialities, reflects China’s particular governing rationalities and practices, and highlights new spatialities of water governance. Our analysis of the remaking of Danjiangkou pushes hydropolitical scholarship to more precisely define the geographies of power in hydrosocial territories.

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.

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.
