Special Issue Information

Dear Colleagues,

Water resources are essential for public health as well as eco-environmental health. Climate change, compounded with rapid urbanization, has severely interfered with the water resource circulation and allocation processes, restricting economic development and causing unprecedent water-related challenges globally. As the United Nations has pointed out, the global demand for fresh water is expected to increase by more than 40% by 2050 due to population growth and urbanization, while the water availability is declining because of the higher climate uncertainty. At least a quarter of people will live in countries or regions that experience intermittent or persistent shortages of fresh water resources, especially in metropolitan areas with concentrated populations and developed economies, where the water resource system has been undergoing long-term overexploitation and become extremely vulnerable. Therefore, water resources have been emphasized as one of critical components in the 2030 Agenda of United Nations Sustainable Development Goals (SDGs 2030). Although extensive research on various temporal/spatial scales has largely focused on water resource shortages or water-related environmental problems under climate change, few studies have emphasized the impact of urbanization on water resources and its health impact. Thus, this Special Issue focuses on, but is not limited to, the following topics:

the mechanism of water resource circulation within the urban system;
the monitoring and simulation of the water resource response to the urbanization process;
the health impact of water resources in urbanized regions;
the evaluation and prediction of the water resource system in urbanization;
the management and optimization of the water resource system under urbanization;
integrated/separated response of water resource system to urbanization and climate change.

Characteristics and Driving Mechanism of Water Resources Trend Change in Hanjiang River Basin

Abstract

Studying the historical and future trends of water resources in a basin and explaining the causes of water resource changes is very important, which is key to the management of water resources in a basin. The Hanjiang River Basin is an important water supply source for southwestern Fujian and eastern Guangdong, but it has an uneven spatial and temporal distribution of water resources and an outstanding conflict between supply and demand. In this study, the SWAT model was used to simulate the conditions of the Hanjiang River Basin in the last 50 years, using long time series climate data to study the characteristics and driving mechanism of water resources trend change. The results show that the water resources in the basin have not increased significantly in the last 50 years, but evapotranspiration has increased significantly. The forecast results for water resources in the future are reduced. The water resource changes in the basin have been unevenly distributed in the last 50 years. Climate change has been the main factor in total water resource change in the basin, while the difference in water resource change trends within the basin is caused by land use. The key reason for the decrease in water resources in the Hanjiang River Basin is the significant increase in evapotranspiration due to the significant increase in temperature. If this situation continues, the available water resources in the basin will continue to decline. In fact, many basins around the world are currently likely to have such problems, such as the 2022 summer drought in the Danube River Basin in Europe and the Yangtze River Basin in China, so this article is informative and representative of future water resources management in the basin.

Determination of Pollution and Environmental Risk Assessment of Stormwater and the Receiving River, Case Study of the Sudół River Catchment, Poland

by Izabela Godyń, Marek Bodziony, Agnieszka Grela, Krzysztof Muszyński and Justyna Pamuła

Abstract

Changes in the land use of urban catchments and the discharge of stormwater to rivers are causing surface water pollution. Measurements were taken of the quality of discharged stormwater from two areas with different types of development: a residential area and a residential–commercial area, as well as the quality of the Sudół River water below the sewer outlets. The following indicators were studied: TSS, COD, N–NO₃, N–NO₂, TKN, TN, TP, Zn, Cu, Hg, HOI, and PAHs. The influence of land use on the magnitudes of flows in the river was modeled using the SCS–CN method and the Snyder Unit Hydrograph Model. The results showed an increase in sealing and a resulting increase in surface runoff. Concentrations of pollutants in stormwater and analysis of the potential amounts of loadings contributed by the analyzed stormwater outlets indicate that they may be responsible for the failure to meet environmental targets in the Sudół River. Environmental risk assessment shows that the aquatic ecosystem is at risk. A risk factor indicating a high risk of adverse environmental effects was determined for N–NO₃, Zn, and Cu, among others.
