“…On the other hand, permafrost thawing in high-elevation headwater catchments, as a result of global warming, promotes groundwater recharge. The number of extreme precipitation events has also increased in the arid and semi-arid region of China (Huang et al 2014). Increase in extreme rainfall events potentially leads to groundwater recharge increase (Zhang et al 2021).…”

The arid and semi-arid regions within China host 75% of the country's cultivated lands. These regions heavily rely on groundwater for drinking, irrigation, industry and energy production. Understanding recharge and discharge processes is critical to managing sustainable use and development of groundwater resources. Recently, groundwater recharge and discharge have been altered by climate change (air temperature, rainfall) and human activities (e.g. irrigation, pumping, reforestation), resulting in significant changes in the quantity, quality, and spatiotemporal distribution of groundwater resources. This essay describes some examples of the associated issues, challenges and opportunities in the arid and semi-arid areas of China.

“…In addition, drought and water quality concerns are expected to increase in the coming years due to climate change and increasing water demand resulting from population growth and urbanization (Darko et al 2022 ; Guo et al 2022 ; Khan et al 2021 ; Lee et al 2019 ; Mukherjee et al 2018 ). Unsustainable water resources development in large basins has also induced various serious environmental problems and geohazards such as soil salinization, land desertification, earth fissures and ground subsidence (Huang et al 2014 ; Wu et al 2014 ). The sustainable development and management of water resources in large basins has become an important topic worldwide, requiring systematic and comprehensive scientific research.…”

Water resources are important in large basins which are important places for human habitation and industrial and agricultural development. The background of editing this thematic issue was introduced and the general water resources situation and water quality status in four major large river basins in the Asian and African continents were briefly summarized to give readers general pictures of water resources development and management in these basins, and these large river basins are the Yellow River Basin, the Yangtze River Basin, the Indus Basin, and the Nile Basin. The thematic issue papers were classified into four clustered topical categories, and the main points of the papers in this thematic issue were summarized. Finally, the perspectives of future sustainable water resources development and management in large river basins were proposed.

“…Overexploitation of groundwater lowers the level of groundwater in an aquifer, and the main reason for seawater intrusion is that the groundwater level in the aquifer is lower than that in the adjacent seawater level (Alfarrah and Walraevens 2018). Seawater intrusion will cause shortages of freshwater resources in coastal land, thus affecting the normal water use of local residents, threatening human health, reducing the inherent irrigation capacity for agriculture, and limiting industrial production (Huang et al 2014). In addition to hindering the economic development of coastal areas, seawater intrusion can also cause harm to the local terrestrial and aquatic ecology in the form of soil salinization, degradation of shrub communities, and deterioration of water quality from mineral water sources (Arslan and Demir 2013;Qi et al 2019).…”

In this paper, the simulation–optimization method is used to study the optimal location of cutoff walls for seawater intrusion. The optimization model is based on minimizing the chlorine concentration of two water sources after 50 years. In order to reduce the computational complexity, a Kriging surrogate model simulation is coupled with the optimization model. Finally, a hypothetical case is used to evaluate the accuracy of the surrogate model and the performance of the optimization model. The results show that the outputs of the Kriging surrogate model and the variable density groundwater simulation model for the same cutoff wall design fit well, and the average relative error of the two outputs is only 2.2% which proves that it is feasible to apply the Kriging surrogate model to this problem. By solving the optimization model, the location of the cutoff wall which minimizes the sum of chlorine concentration of the two water sources after 50 years is obtained. This provides a stable and reliable method for the site selection of cutoff walls for future projects intended to prevent and control seawater intrusion.
