Summary: This study develops and compares different models to predict groundwater flooding in a lowland karst area of Ireland. The results show that a NARX model taking inputs of the past 5 days' flood volume, rainfall data, and tidal amplitude data has the best performance in predicting floods up to 30 days into the future. Additionally, real-time telemetric monitoring of water levels can be used to provide an early warning flood warning tool.

Summary: Most lake temperature studies have focused on climate-induced changes at the lake surface, but few have investigated temperature variations in lakes situated north of the Arctic Circle. This study analyzes a 60-year observational data set from Lake Inari in Finland and finds a summer warming trend at the lake surface while deepwater temperatures remain largely unchanged, resulting in a strengthening of summer stratification in this high latitude lake.

Summary: Longitudinal environmental heterogeneity and directionality of water movement play important roles in the distribution patterns of riverine plankton communities. This study examines the impact of urbanization on plankton assembly processes in a river in Southeast China. The results reveal that despite short distances between sampling sites, plankton community similarity decreases with increasing distance from pristine upstream areas towards downstream urban areas. Deterministic and stochastic processes drive the distribution patterns of phytoplankton and bacterioplankton, respectively, suggesting a balance between dispersal and local selective pressures. These findings highlight the importance of plankton-based ecological approaches in managing rivers draining urbanizing watersheds.

Summary: Water scarcity has become a prevalent issue in many regions over the past decades. Previous assessments largely overlooked the role of green water in supporting crop production. This study proposes an agricultural water scarcity index (WSIAW) that combines green and blue water to measure water scarcity. The results show that the WSIAW provides a better understanding of water scarcity compared to blue water assessments alone, and reveals an increasing severity of water scarcity in major agricultural regions, mainly due to expanding cropland and competing water withdrawals. The proposed WSIAW is important for addressing global water scarcity issues.

Summary: In this study, radar rainfall nowcasting was used to construct discharge forecasts for Dutch catchments. The results showed that both rainfall and discharge forecast errors increase with increasing rainfall intensity and spatial variability. The performance of discharge forecasts depends on the initial conditions, with faster increase in forecast error for shallow groundwater table. Among the tested algorithms, Rainymotion DenseRotation, Pysteps deterministic, and probabilistic methods outperformed the others in discharge forecasting. The study also found that the threshold exceedance forecasts provided advanced warning compared to no rainfall forecasts, with PS-D and PS-P methods producing lower false alarm ratio and inconsistency index values.

Summary: Changes in physical oceanography in the Northwest Atlantic have impacted the foraging ecology and distribution of North Atlantic right whales. The study analyzed right whale sightings from 1990 to 2018 and found significant differences in foraging habitats over three decades. The analysis also revealed that changes in foraging habitats were driven by a decline in prey in traditional habitats, rather than an increase in prey in new habitats.

Summary: Understanding the role of reservoirs in the terrestrial water cycle is crucial for sustainable water resource management, especially in China where reservoirs are extensively built. However, the lack of continuous, long-term reservoir operation records and an accurate modeling tool have posed scientific challenges. In this study, a continental-scale land surface-hydrologic model is developed to explicitly represent 3,547 reservoirs in China and quantify their seasonal dynamics and role in terrestrial water storage.

Summary: About 15 Tg of plastic enter the ocean each year, with the majority accumulating in marine sediments rather than floating on the surface. From 1950 to 2010, an estimated 170 Tg (25-900 Tg) of nonfibrous plastic has accumulated in marine sediments globally, confirming their role as a major sink for plastic.

Summary: Groundwater use is essential for economic production, but its unsustainable use threatens environmental flows, sustainable development, and future food security. This study analyzes the complete supply chain of China and finds that groundwater depletion primarily occurs in water scarce regions in the country, and a significant amount of depleted groundwater is incorporated into industrial and tertiary products consumed by major cities.

Summary: This study investigates the transitions of dissolution patterns in rock fractures under different flow-rate and reaction-rate conditions. Three distinct dissolution morphologies, namely compact, wormhole, and uniform patterns, are observed and quantified. The critical Peclet numbers for the transitions increase with the reaction rate. A theoretical model based on the growth of dissolution channels in the flow and transverse directions is established to describe the transitions. The phase diagram predicted by the model agrees well with experimental results and previous studies, enhancing the understanding of fracture aperture expansion in dissolution processes.

Summary: The concentrations of solutes in seepage lakes are influenced by precipitation and groundwater inputs. Seepage lakes in areas where road salt is applied may face a high risk of salinization. Monitoring of Sparkling Lake over 40 years shows that chloride concentrations have steadily increased, indicating terrestrial retention as a factor. When modeling future chloride contamination risk, the retention of chloride on the landscape should be considered.

Summary: This study investigated the dual water isotopes in the northwestern South China Sea during Typhoon Wipha to address the controversial issue of nutrient increase in coastal marine ecosystems. The results showed that weak mixing existed among different water masses before the typhoon, but was strengthened after the typhoon with the drop in temperature and salinity. Upwelling was found to be stronger on the right side of the typhoon path than on the left, and nutrients predominantly originated from the coastal diluted water input in the upper nearshore layer.

Summary: The Wubi input method has become a widely used Chinese input method, especially in computer input, and has been widely recognized by users. The Wubi input method was developed by Xu Zheng in the early 1980s, and the initial version was based on the input method of radicals. Later, after continuous improvement and perfection, multiple versions were launched. The characteristics of the Wubi input method are fast, accurate, and can be personalized based on the user's input habits.
