The South-to-North Water Diversion Project consists of long-distance water delivery channels and a complicated geological environment along the way. To deal with the operation safety of the water conveyance channels in the middle route of the South-to-North Water Diversion Project, this study analyzes six failure modes: structural cracks, poor water delivery during ice periods, instability of canal slopes, material aging, abnormal leakage, and foundation defects. Based on FMEA, a multigranularity language evaluation method that can be converted into interval intuitionistic fuzzy numbers is used to evaluate the severity (S), occurrence (O), and detection difficulty (D) of the six failure modes. Interval intuitionistic fuzzy entropy is used to calculate the weights of the risk factors. Finally, a ranking model of each failure mode is built based on the TODIM method. The final ranking results show that the risk of abnormal leakage is the largest, and the risk of poor water delivery during ice periods is the smallest. The feasibility and validity of the calculation results are verified by comparing them with the ranking results of the traditional RPN and TOPSIS methods. The TODIM-FMEA risk assessment model offers a new solution to the problem of risk assessment for water transfer projects.

Abstract Based on fuzzy mathematics, a risk assessment model of floodwater resources utilization in a water diversion project was established based on the fuzzy network analytic hierarchy process (F-AHP). First, the weight of each factor was determined through AHP, and then the fuzzy evaluation method (FEM) was used for analysis and comparison. Finally, the optimal decision scheme was determined. The model was applied to the Eastern Route of the South-to-North Water Diversion Project (SNWDP) for floodwater resources utilization risk assessment. The results show that the model can utilize the risk factors of floodwater resources for identification and sorting, and then make a risk evaluation. The risk of floodwater resources utilization in a normal flow year is the lowest and the benefit is remarkable, providing a reasonable control scheme, and reducing unnecessary losses for the risk of floodwater resources utilization.

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.

Message mapping is useful for communications which should be easy to understand and reflect the concerns of stakeholders when abrupt trans-boundary environmental pollution occurs in river basin. This paper describes the process undertaken to develop the message maps, and lessons learned thus far. The working group developed a message map for one part of east route of the South-to-North Water Diversion Project (from Yangtze River to Hongze Lake).The message map can help give clear and concise information for stakeholders communication in a crisis where emotions are high, and provides information support for information map visualization in the near future.

The water-ways were complicated and intertwined in the Hongze Lake section of South-to-North Water Transfer Project. A complex natural environment and multitudinous chemical enterprises here result in environmental risk sources in this region.This study, with the Hongze Lake as center, aims to investigate information of pollution sources about 22 plants in the surrounding cities.We construct recognition evaluation index system for watershed risk sources, calculate risk coefficient about the risk sources by R-AHP Comprehensive Evaluation and finally determine the 4 risk levels. The results can help to make identification mark taking the grading alert colors and it is significant for decreasing the probability of major environmental pollution accidents.

Global Concern

Water scarcity in densely populated areas is a global concern. In China, ensuring water supply and quality in the middle of the South-to-North Water Diversion Project has become a major challenge due to the complexity and diversity of landscape features and the trunk canal construction in the crossing area of this route. Precise assessments of the pressures on water protection along the route are urgently needed. This article provides a rigorous methodological framework to assess water quality protection, identifying the intensity of human disturbance along the route within 2-km radius buffer areas on both sides of the trunk canal, based on land-use changes from 2005 to 2015. The results show that more than 10,000 ha of pervious surfaces were transformed into impervious surfaces, leading to undesirable outcomes. The results of this study can be used for decisive support in China’s environmental management, such as with main functional zoning policy and ecological red lines policy.
