Special Issue Information

Dear Colleagues,

Climate change presents unprecedented challenges to the availability, quality, and distribution of water resources and management worldwide, from altered hydrological cycles and extreme events to rising competition for water across sectors. This Special Issue will focus on innovative approaches, tools, and strategies for adapting to climate change within the field of water resource management from high-quality, original research and reviews that address how water resource management systems and society can adapt to climate-induced stressors through science, policy, and practice.

We invite the submission of contributions that explore the following topics:

  • Adaptive governance and water policy reforms;
  • Integrated water resource management (IWRM);
  • Innovative modeling and decision-support tools;
  • Nature-based solutions and ecosystem-based adaptation;
  • Case studies on urban, agricultural, or transboundary water adaptation;
  • Adaptation to climate change and extreme hydrological events induced;
  • Water resource systems in transition;
  • Water quality under climate stressors;
  • Socioeconomic and equity considerations.

This Special Issue aims to foster a cross-disciplinary dialog, improve resilience in water systems, and inform decision-making under future climate scenarios. It seeks to bridge scientific research with practical applications, supporting adaptive decision-making in water resource planning under uncertainty. It will contribute to the ongoing discourse on sustainable water management and climate resilience by bringing together interdisciplinary insights from engineering, hydrology, environmental sciences, and policy frameworks for water resource sustainability.

Drought leads to declining water levels and reduced water volume in lakes, significantly altering their water quality. Current research has primarily examined water quality during drought episodes or compared conditions before and after such events. However, the variations in water quality indicators and their relationships with hydrological factors across different drought stages, particularly during development and recovery periods, remain poorly understood. To address this gap, we investigated the stage-specific impacts of hydrological drought on lake water quality. Hydrological drought events were identified and segmented into development and recovery stages using the Standardized Water Level Index. Eight water quality indicators, including total nitrogen (TN) and total phosphorus (TP), were analyzed together with hydrological variables using Grey Relational Analysis (GRA). Poyang Lake, the largest freshwater lake in China, served as the case study. The results revealed significant spatio-temporal heterogeneity in both drought characteristics and water quality responses. Development periods were generally longer than recovery periods. Dissolved oxygen (DO) was consistently lower during drought development, whereas TP increased during recovery. GRA indicated that the main drivers of TN and TP shifted across drought stages. During the development period, TN and TP were more closely coupled, and permanganate index and turbidity exerted strong influences. In contrast, during the recovery period, TN was primarily associated with conductivity, while TP became mainly dominated by turbidity. This paper not only supplements the theoretical understanding of the interaction between hydrological drought and water quality, but also provides scientific support for water quality early warning, and the water resource management of large freshwater lakes under drought scenarios.

Climate change increasingly threatens the sustainability of regional water resources; therefore, robust station-scale precipitation projections are essential for basin-level planning. This study aims to develop and evaluate a hybrid, machine-learning-based statistical downscaling framework to generate monthly precipitation projections for the 21st century in the Büyük Menderes Basin, western Türkiye, using the HadGEM3-GC31-LL global climate model from the CMIP6. Monthly observations from 23 rainfall observation stations and ERA5 reanalysis predictors were employed to train station-specific Random Forest (RF) models, with optimal predictor sets identified through a multistage selection procedure (MPSP). Coarse-resolution general circulation model (GCM) fields were harmonized with ERA5 data using a three-stage inverse distance weighting (IDW), Delta, and Variance rescaling approach. The downscaled projections were bias-corrected using Quantile Delta Mapping (QDM) to maintain the climate-change signal. The RF models exhibited strong predictive skill across most stations, with test Nash–Sutcliffe Efficiency (NSE) values ranging from 0.45 to 0.81, RSR values from 0.43 to 0.74, and PBIAS values from −21.99% to +5.29%. Future projections indicate a basin-wide drying trend under both scenarios. Relative to the baseline, mean annual precipitation is projected to decrease by approximately 12.2, 19.6, and 33.7 mm in the near (2025–2050), mid (2051–2075), and late (2076–2099) periods under SSP2-4.5 (Shared Socioeconomic Pathway 2-4.5, a moderate greenhouse gas scenario). Under the high-emission SSP5-8.5 scenario, projected decreases are 25.2, 53.2, and 86.9 mm, respectively. Late-century reductions reach approximately 15–22% in several sub-basins. These findings indicate a substantial decline in future water availability and underscore the value of RF-based hybrid downscaling and trend-preserving bias correction for water resources planning in semi-arid Mediterranean basins.

The SCS-CN (Soil Conservation Service Curve Number) model is important for flood forecasting as it provides a relatively simple and widely used methodology for estimating the amount of surface runoff from a rainfall event, which is a crucial input in predicting flood volumes and peaks in ungauged or data-scarce watersheds. Thus, the authors developed a hydrological model based on the SCS-CN curve methodology and GIS (Geographic Information Systems) to estimate the flood hydrograph in the upper parts of the Biała Lądecka River basin in Poland. The numerical model was calibrated based on the data available from the Polish Institute of Meteorology and Water Management (IMGW). The output of the model demonstrates the effect in the flood hydrograph at the town of Lądek-Zdrój. Additionally, hydraulic routing calculations were included to analyze the possible causes of the dam failure of the Stronie Śląskie reservoir in the year 2024. The main purpose of this study is to corroborate the influence of climate change on flood events and their consequences, as well as to assist in forecasting future catastrophic hydrological events and thus earlier adaptation and reinforce the infrastructure in our territories against future flooding.

Climate change is intensifying hydrological extremes, posing growing threats to the safety and operational reliability of embankment dams worldwide, particularly those in regions susceptible to heavy rainfall and flooding. This study evaluates the overtopping risk for Batu Dam, a critical flood mitigation and water supply structure near Kuala Lumpur, Malaysia, under future climate scenarios, with the aim of informing risk-informed dam safety strategies. Using historical hydrological data (1975–2020) and downscaled climate projections from the CMIP5 database under three Representative Concentration Pathways (RCP4.5, RCP6.0, RCP8.5), we conducted flood routing simulations and probabilistic risk assessments employing the iPRESAS software. Our results demonstrate that the annual probability of overtopping increases substantially under higher-emission scenarios, reaching up to 0.08% by the late century under RCP8.5, driven by increased frequency and intensity of extreme rainfall events. These projections highlight significant spillway capacity limitations and underscore the heightened risk of downstream consequences, including economic losses exceeding RM 200 million and potential loss of life surpassing 2900 individuals in worst-case scenarios. The findings confirm the urgent need for both structural adaptations, such as spillway expansion and crest elevation, and non-structural measures, including enhanced real-time monitoring and early warning systems. This integrated approach offers a robust and replicable framework for strengthening dam safety under evolving climate conditions. Full article
