“…The SNWTP was officially opened on 12 December 2014, with a total area of 155,000 square kilometers within the scope of water supply and a total length of 1277 km of trunk canals. The SNWTP focuses on solving the problem of water resource shortages along the route, providing water for production and living as well as industrial and agricultural in a dozen large and medium-sized cities along the route [38,57,58]. The SNWTP effectively promotes the restoration and protection of the water environment in the strategic areas of national construction, such as the integration of Beijing, Tianjin, and Hebei, and has significant social, economic, and ecological benefits.…”

North China (NC) is experiencing significant groundwater depletion. We used GRACE and GRACE-FO RL06 Level-2 data with Mascon data from April 2002 to July 2022. We fused these two types of data through the generalized three-cornered hat method and further combined them with hydrological models, precipitation, in situ groundwater-level, and groundwater extraction (GWE) data to determine and verify temporal and spatial variations in groundwater storage (GWS) in NC. We quantitatively assessed groundwater sustainability by constructing a groundwater index in NC. We further explored the dynamic cyclic process of groundwater change and quantified the impact of the South-to-North Water Transfer Project (SNWTP) on GWS change in NC. The overall GWS shows a decreasing trend. The GRACE/GRACE-FO-derived GWS change results are consistent with those shown by the in situ groundwater-level data from the monitoring well. Groundwater in NC is in various states of unsustainability throughout the period 2002 to 2022. The SNWTP affected the water use structure to some extent in NC. This study elucidates the latest spatial–temporal variations in GWS, especially in the groundwater sustainability assessment and quantitative description of the effects of the SNWTP on changes in GWS in NC. The results may provide a reference for groundwater resource management.

Interbasin water transfer is widely used to ensure water supply security in water-scarce regions. However, the evolutionary mechanism of the water supply system in the receiving area under the impact of water diversion projects remains unclear. The theory of dissipative structures is utilized in this study to analyze the entropy flow of the water supply system in the receiving area. An entropy flow measurement index system is constructed, and the transformed Brussels model is combined to determine the evolutionary direction of the water supply system under the influence of the water diversion project. Taking Zhengzhou City as an example, the results show that after the South-to-North Water Transfer Project commenced operation, the evolutionary value increased from 0.048 to 0.199, indicating that the system is evolving toward a dissipative structure. In contrast, without the South-to-North Water Transfer Project, the evolutionary value decreased from −0.850 to −1.045, indicating that the system is evolving toward a nondissipative structure. Upon further discussion, it was found that the South-to-North Water Transfer enhanced the negative entropy of environmental management in Zhengzhou's water supply system, reduced the positive entropy of the water supply mode, and steered the system toward sustainable and healthy evolution.
