Beijing is located in a semiarid region, and water shortage is a common problem in the city. Along with the rapid increase in water demand, due to fast socioeconomic development and an increase in population, a shortage of water resources and a deterioration of the water environment have become obstacles to sustainable socioeconomic development in Beijing. In the long run, sustainable water resources management, water conservation, and completion of the south to north water diversion project will solve the problem. This paper introduces the water resources situation in Beijing; analyzes future water demand; and discusses the actions of water saving, nontraditional water resources exploitation, wetland construction, and water environment protection. The paper also explains the importance of the south to north water diversion project and the general layout of the water supply strategy, water distribution system, and methods to efficiently use the diverted water in Beijing.Key words: water resources, water supply, water saving, water recycling, water diversion.

Having become the tool to resolve the watershed environmental protection and local development contradictions, ecological compensation has been drawing increasing attention. Conflicts in environmental protection and regional development of the middle route water source area of the South-to-North Water Transfer Project urgently need to be resolved by the ecological compensation. However, the ecological compensation remains unsound yet. The author of this paper introduces the existing ecological compensation policy of the middle route water source area, analyzes main problems existing in ecological compensation policies in the middle route water source area, e.g. lack of legislative support for ecological compensation, insufficient researches on compensation standards, limited channel of funds and unsound evaluation mechanism and ultimately puts forward some suggestions on the improvement of ecological compensation policies of the water source area.

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.

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.

With the development of the economy, human activities have more and more effects on natural environment. The large water conservancy and hydropower projects caused great multi-aspect influences on the environmental changes. The unreasonable activities of mankind in water resources exploitation have deteriorated the natural environment, intensifying the conflicts between human beings and the nature. Environment and natural disasters have brought forward rigorous challenge on the survival and development of the mankind. The concept of environmental variation is proposed in analyzing the processes of environmental change, and the reparation methods for the river environment variation have been stated as well. Styles of river environmental variation can be classified according to characteristics of the river and of human activities. The characteristics and the consequences of the environmental variation in the estuary of Yellow River are analyzed, so have the reparation methods. With the development of the economy, the human activities have more and more effects on natural environment. The large Water Conservancy and Hydropower Projects, such as the big-dam-building on the river, the water-transferring project, the water resources-exploiting project, and the sewage-discharge project, etc., have caused great multi-aspect influences on the environmental changes. The unreasonable activities of mankind in water resources exploitation have deteriorated the natural environment, intensifying the conflicts between the human beings and the nature. Environment and natural disasters have brought forward rigorous challenge on the survival and development of the mankind. Some abnormal environmental changes (Environment Variation) can be observed in rivers, influencing our life greatly, especially the environmental variation in the mouth of Yellow River.

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.

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.
