Special Issue Information

Dear Colleagues,

Affected by global climate change and rapid socio-economic development, China suffers from severe water security pressure, especially in terms of water shortages, flood disasters and water-related ecological and environmental problems. The solution to these problems requires comprehensive research across different disciplines.

Focusing on discussing China’s water issues, we carried out a series of academic exchanges over a long period. The well-known “China Water Forum”, launched in 2003 and held annually, focuses on discussing solutions to China’s water issues. By 2023, the forum was successfully held for 20 sessions. “Water Science Development Forum”, launched in 2007 and held annually, focuses on promoting the multidisciplinary integration of other disciplines with water science research. By 2023, the forum was successfully held for 16 sessions. “Water Science Lectures”, launched in 2021, is an open, shared and non-profit public welfare lecture. A report will be arranged for each lecture, which will be lectured and presided over by invited famous researchers.

The Editorial Department of Water Journal cooperates with “China Water Forum”, “Water Science Development Forum” and “Water Science Lectures” to set up a series of columns. At least one column is planned each year currently. The column established in 2024 is “China Water Forum 2024”. We welcome scholars and graduate students participating in the above-mentioned conferences, as well as scholars who study water issues in China, to submit full texts of their unpublished manuscripts. The received papers will be professionally peer-reviewed and recommended for publication by the editorial board.

We invite submissions on, but not limited to, the following topics:

（1）Climate change and hydrology     Director: Dunxian She, Rong Gan

（2）Water problems and human–water relationship control      Director: Zengliang Luo, Qiting Zuo

（3）Water environment and ecology       Director: Fuqiang Wang, Jiaqi Zhai

（4）Water information technology and modeling     Director: Lei Zou, Xiuyu Zhang.

The assessment of streamflow patterns and their complexity variations across multiple timescales within river basins is a crucial aspect of water resource management and policy formulation. In this study, the Hurst coefficient, Mann–Kendall nonparametric test method, streamflow pattern indices, and sample entropy (SampEn) analyses were used to investigate the streamflow pattern in the whole Yangtze River basin at annual, monthly, and daily scales. The results show that with the increase in the time resolution, the streamflow shows more complex changing characteristics and streamflow changes more obviously on the monthly timescale than on the annual one. The annual mean streamflow decreases only in some of the tributaries, while the monthly streamflow shows significant increasing trends in the dry season and significant decreasing trends in the late wet season in almost the whole basin. Results also show that the minimum extreme streamflow indices increase in almost the whole basin. The maximum indices show decreasing trends in most of the tributaries and the Yichang gauge in the main reach. The streamflow complexity in the tributaries is higher and the complexity increases from upstream to downstream along the main reach in the basin. Along the main reach, the average SampEn increases downstream of the reach with values of 0.05, 0.07, 0.10, 0.12, 0.14, and 0.14 at Shigu, Pingshan, Cuntan, Yichang, Hankou, and Datong, respectively. These findings are helpful for understanding the hydrological characteristics and water resource management in the Yangtze River basin. Full article

With the increasing environmental impacts of human activities, the problem of polygenic multipollutants in groundwater has attracted the attention of researchers. Identifying the hydrobiogeochemical characteristics of the surface sewage that replenishes groundwater is crucial to addressing this problem. The input of polygenic multipollutants into groundwater leads to not only the mechanical superposition of pollutants but also the formation of secondary pollutant types. The evolution of polygenic multipollutants is influenced by aquifer characteristics, carbon sources, microbial abundance, etc. Therefore, this study took a sewage leakage point in Northwest China as the research object, carried out a controlled laboratory experiment on the impact of sewage discharge on groundwater, and, combined with long-term field monitoring results, determined the main hydrobiogeochemical processes of polygenic multipollutants and their secondary pollutants. The results showed that the redox environment and the gradient change in pH were identified as the most critical controlling factors. In oxidative groundwater during the early stage of vertical infiltration, sewage carries a substantial amount of NH4+, which is oxidized to form the secondary pollutant NO3−. As O2 is consumed, the reduction intensifies, and secondary pollutants NO3−, Mn (IV), and Fe(III) minerals are successively reduced. Compared with the natural conditions of rainwater vertical infiltration, the reaction rates and intensities of various reactions significantly increase during sewage vertical infiltration. However, there is a notable difference in the groundwater pH between sewage and rainwater vertical infiltration. In O2 and secondary pollutant NO3− reduction, a large amount of CO2 is rapidly generated. Excessive CO2 dissolves to produce a substantial amount of H+, promoting the acidic dissolution of Mn (II) minerals and generation of Mn2+. Sewage provides a higher carbon load, enhancing Mn (II) acidic dissolution and stimulating the activity of dissimilatory nitrate reduction to ammonium, which exhibits a higher contribution to NO3− reduction. This results in a portion of NO3− converted from NH4+ being reduced back to NH4+ and retained in the groundwater, reducing the denitrification’s capacity to remove secondary NO3−. This has important implications for pollution management and groundwater remediation, particularly monitored natural attenuation. Full article

The natural hydrological cycle of basins has been significantly altered by climate change and human activities, leading to considerable uncertainties in attributing runoff. In this study, the impact of climate change and human activities on runoff of the Ganjiang River Basin was analyzed, and a variety of models with different spatio-temporal scales and complexities were used to evaluate the influence of model choice on runoff attribution and to reduce the uncertainties. The results show the following: (1) The potential evapotranspiration in the Ganjiang River Basin showed a significant downward trend, precipitation showed a significant upward trend, runoff showed a nonsignificant upward trend, and an abrupt change was detected in 1968; (2) The three hydrological models used with different temporal scales and complexity, GR1A, ABCD, DTVGM, can simulate the natural distribution of water resources in the Ganjiang River Basin; and (3) The impact of climate change on runoff change ranges from 60.07% to 82.88%, while human activities account for approximately 17.12% to 39.93%. The results show that climate change is the main driving factor leading to runoff variation in the Ganjiang River Basin. Full article
