“…In addition, these reservoirs and pump stations are operated jointly to meet the water demand in the water recipient area. Water can be transferred among different reservoirs by the pump stations to deal with water variability (Davies et al 1992;Wu et al 2020). For example, at off-peak time, water is pumped from lower elevation reservoirs to store in higher elevation reservoirs with higher potential energy.…”

Most of inter-basin water diversion projects have been constructed to cope with the water shortage problems. These projects usually have multiple reservoirs and pump stations connected to each other. Most previous studies focus solely on the operation of reservoirs aiming to supply more water rather than the joint operation of the reservoir-pump station system. Project operation ignoring the pump station may be not cost effective. In addition, future water availability is of great uncertainty that will affect the system performance. Therefore, the main purpose of this study is to evaluate the tradeoffs between water supply and power net revenue (considering power generation by hydropower stations and power consumption by pump stations) under different water availability scenarios which can be used to inform policies. A resilience metric is introduced to evaluate the joint system performance. An optimization model including two objectives: social perspective (minimum of total water shortage) and economic perspective (maximum of power net revenue) is considered for the study area: Hanjiang-to-Weihe River Valley Water Diversion Project. Results mainly show that two objectives are in a contradictory relationship. If future streamflow does not decrease, the water supply sector could at least meet 50% of the water demand in recipient area.

“…In particular, the impact of these water conservation projects on the water quality of the Yangtze River has attracted international attention (Zhuo et al, 2017).Many studies have been devoted to the water quality assessment in the Yangtze River and many methods have been applied such as single factor method (Lv and Mi, 2011),TOPSIS (Technique for order preference by similarity to an ideal solution) model (Wang et al, 2017), multiple comparative test and contrast analysis (Li et al, 2017). Furthermore, the variation range of water flow is limited to a small range and the natural environment on which river life depends tends to be monotonous, which as further led to ecosystem degradation (Wu et al, 2020). Some of the effects of reduced sediment concentration, delayed temperature effects, and changes in the relationship between rivers and lakes are still being assessed (Bing et al, 2019;Gao et al, 2020).…”

Yangtze River, the longest river in Asia, provides 40 percent of freshwater in China and plays an important role in ecological biodiversity. However, this ecosystem has been deteriorated by the continuously construction of reservoirs and hydropower stations. Many investigations have been carried for the biodiversity, hydrological indicators, and species distribution along Yangtze River caused by dam construction. As a result, the ecological operation has been gradually applied to mitigate the negative effects of water conservancy projects. In order to well know recent advances in the study of fish habitat in the Yangtze River Basin, 424 original papers published from 2000 to 2020 using bibliometrics were compiled in this research to analyze the developing trends including topics, data, and research status. The results of literature statistics showed that the related research fields on the effects of the reservoir on hydrological indicators mainly focused on negative impact caused by hydrological changes, water temperature effect, and sediment variation. In the studies on the habitats of fish, the four major Chinese carps and Chinese sturgeon were the main objects of concern, in which multi-objective joint operation, cascade reservoir operation, and model coupling have been widely adapted.

This paper compares and analyzes the effects of different amounts of government subsidies and subsidy patterns on water supply, pricing, and profit distribution, and takes water diversion project supply chain composed of water transfer company and the water work as the study object, using financial accounting method innovatively, establishing non-cooperative and cooperative game models of two under government subsidies. The results show that as the number of subsidies increased, the optimal amount of water supply and the profits increased, but the price of water work decreased. When the amount of subsidy stays same, the price of water plant also stays same. However, the price of the water transfer company is constantly changing, the higher the proportion of subsidies it received, the lower the price. In terms of data, the authors take a practical example – the Tao River Water Diversion Project to analyze. This paper’s limitation is that the conclusion is based on a single water transfer company and a single water plant as the research object. However, the actual situation of the water transfer project is that a water transfer company faces a complex supply chain network formed by many water plants and farmers’ water users’ associations.
