Special Issue Information

Dear Colleagues,

Urbanization is reshaping landscapes globally, leading to increasingly complex hydrological and water resource management challenges in urban–rural transitional and coastal areas. Rapid population growth, climate change, and urban expansion intensify pressure on water systems, demanding sustainable approaches for resource allocation, pollution control, and flood resilience. Coastal zones, where urban development often meets critical ecosystems, face unique challenges such as saltwater intrusion, rising sea levels, and extreme weather impacts that complicate water management. Additionally, the integration of agricultural water management in urban and peri-urban settings is vital for balancing the water needs of food production with those of expanding urban populations. This Special Issue, "Global Perspective on Hydrology and Water Resources Management in Complex Urban Areas", seeks contributions that provide insights into hydrological processes, innovative water management strategies, and the role of emerging technologies in coastal or urban–rural transitional areas. By exploring case studies, modeling advances, and policy frameworks, this issue aims to present comprehensive strategies that can enhance water resilience and security in metropolitan environments. In this regards, we encourage submissions that address water quality, flood-drought risk, integrated water management, agriclutural water use optimization, and policy implications for densely populated urban regions or urban–rural and coastal areas, providing solutions that can be adapted across diverse global contexts.

Mountain reservoirs are often exposed to geological hazards, particularly landslides, posing significant risks to dam stability. This study conducted scaled experiments to investigate the surge pressure loads induced by landslides entering reservoirs under controlled conditions. Landslide volumes ranging from 500 cm3 to 2000 cm3 and slope angles of 35° and 45° were tested under different scenarios. Key parameters, including landslide volume, slope angle, water depth, and the distance between the landslide impact point and the dam were systematically varied to evaluate their effects on the maximum impact pressure along the reservoir bank. Through a systematic analysis of landslide volume, slope angle, water depth, and impact distance, their effects on maximum impact pressure were evaluated. Dimensional analysis and regression modeling were then used to develop a predictive model for maximum impact pressure. The results indicate that larger landslide volumes and steeper slopes amplify impact pressure, whereas greater water depths and larger distances from the impact point reduce it. Empirical equations for predicting impact pressure on reservoir banks and dam faces demonstrated strong agreement with experimental data. These findings offer crucial insights into the mechanisms influencing impact pressures in reservoirs and provide practical guidance for dam stability assessments under landslide-induced surge conditions.

Subsurface drip irrigation is an advanced technique that significantly enhances agricultural water efficiency and conserves irrigation resources. The Heilonggang region is highly representative of the maize–wheat rotation system in China. This region was selected for conducting operations and maintenance experiments on subsurface drip irrigation systems. The primary objective of this study was to determine the most suitable type of drip tape for application in the North China Plain and to identify specific maintenance measures necessary to ensure the long-term functionality of subsurface drip irrigation systems. The experiment was conducted in Jing County, Hengshui City. Anti-blocking drip tape (Netafim Co., Ltd. Beijing, China) with automatic functionality was evenly laid in the test area. The experimental area was divided into six rotational irrigation groups. The key parameter examined in this single-factor experiment was the drip tape wall thickness, with values of 0.2, 0.225, 0.25, 0.28, 0.31, and 0.38 mm. Drip tape treatments were randomly sampled in rotational irrigation groups, and there were three repeat plots in each treatment. Each replicate plot contained ten drip irrigation belts spaced 60 cm apart, with an interval of more than 2 m between adjacent plots. The subsurface drip irrigation system was installed in October 2023. Prior to irrigation, drip tape troubleshooting was conducted and recorded manually on 12 March 2024 (wheat regreening stage) and 29 June 2024 (maize-sowing stage). The experimental findings indicated that the primary factor influencing the stability of the irrigation system was the wall thickness of the drip tapes, while other system components operated efficiently. A significant correlation was observed between the wall thickness of the drip tape and the number of water leakage points (p < 0.05), with an absolute correlation coefficient exceeding 0.9. The number of leakage points in drip tapes with wall thicknesses of 0.2–0.28 mm (267 instances) was significantly higher than those with wall thicknesses of 0.31–0.38 mm (29 instances), primarily due to damage caused by mole crickets and wireworms. Following the injection of 40% phoxim, 2.5% lambda-cyhalothrin, and 70% imidacloprid insecticides (at a cost of 16.7 USD·ha−1) into the subsurface drip irrigation system, the insect pests were nearly eradicated within one month. A cumulative cost evaluation over a 6–10-year period recommended the use of drip tapes with a wall thickness of 0.31 mm and the application of insecticides every 1–2 months to maintain optimal system performance in this region. These measures can effectively support the stable operation of this irrigation technique at a relatively low cost. Full article

Quantifying the water budget in the Great Salt Lake (GSL) basin is a nontrivial task, especially under a changing climate that contributes to increasing temperatures and a shift towards more rainfall and less snowfall. This study examines the potential impacts of temperature thresholds on the water budget in the GSL, emphasizing the influence on snowmelt, evapotranspiration (ET), and runoff under varying climate warming scenarios. Current hydrological models such as the Variable Infiltration Capacity (VIC) model use a universal temperature threshold to partition snowfall and rainfall across different regions. Previous studies have argued that there is a wide range of thresholds for partitioning rainfall and snowfall across the globe. However, there is a clear knowledge gap in quantifying water budget components in the Great Salt Lake (GSL) basin corresponding to varying temperature thresholds for separating rainfall and snowfall under the present and future climates. To address this gap, the study applied temperature thresholds derived from observation-based data available from National Center for Environmental Prediction (NCEP) to the VIC model. We also performed a suite of hydrological experiments to quantify the water budget of the Great Salt Lake basin by perturbing temperature thresholds and climate forcing. The results indicate that higher temperature thresholds contribute to earlier snowmelt, reduced snowpack, and lower peak runoff values in the early spring that are likely due to increased ET before peak runoff periods. The results show that the GSL undergoes higher snow water equivalent (SWE) values during cold seasons due to snow accumulation and lower values during warm seasons as increased temperatures intensify ET. Projected climate warming may result in further reductions in SWE (~71%), increased atmospheric water demand, and significant impacts on water availability (i.e., runoff reduced by ~20%) in the GSL basin. These findings underscore the potential challenges that rising temperatures pose to regional water availability. Full article
