Summary: This article presents a hydrological reconstruction of the Upper Colorado River Basin using hourly temporal resolution and 1-km spatial resolution from October 1982 to September 2019. The validated dataset includes various hydrologic variables such as streamflow, water table depth, snow water equivalent (SWE), and evapotranspiration (ET). These datasets provide a long-term simulation of natural flow for one of the most over-allocated basins in the world.

Summary: Studies in the Colorado River Basin have found that warming has caused declines in streamflow since 2000, especially in the Upper Basin. However, it is uncertain if increased precipitation variability could outweigh the effects of future warming. To address this, a model framework was used to project streamflow across the entire basin, showing significant declines in streamflow due to warming and decreased precipitation. The spatial analysis provided actionable information for water management in the basin.

Summary: This study explored the hydro-climatic and socio-ecological determinants affecting terrestrial water storage (TWS) variations in the Yellow River Basin in northern China. Precipitation, minimum temperature, runoff, base flow, water withdrawal, and NDVI were identified as the main drivers of TWS variations, with minimum temperature and runoff playing a significant role.

Summary: The study found that low flows in the Delaware River Basin are influenced by biophysical and climatic drivers, exhibiting different spatial patterns in different years and regions. Despite an increase in precipitation recently, 7-day low flows generally show an increasing trend, while low flows have decreased in the Coastal Plain physiographic province due to land and water management effects.

Summary: This study updated the vegetation parameters of the VIC hydrologic model using MODIS observations and improved streamflow simulations in the Colorado River basin. While both configurations performed similarly in historical simulations, they projected different changes in streamflow under future climate scenarios. The MODIS-based configuration simulated a smaller change, whereas the previous configuration predicted a decrease in streamflow. These results emphasize the importance of accurately characterizing vegetation and better constraining climate sensitivities in hydrologic models.

Summary: The study addressed the impact of climate variability and land-use change on streamflow and pollutant loadings in the 3S River Basin over a 30-year period. Climate variability was found to have a significant effect on streamflow and pollutant loadings, with the Sekong and Srepok River Basins showing stronger responses to climate variability compared to land-use change. The findings of the study provide valuable information for decision makers in developing sustainable water resources management strategies.

Summary: Fires have adverse effects on forested watersheds, but the impact on water resources is uncertain. This study evaluates the effects of two major wildfires in the Lower Colorado River Basin, considering various factors such as elevation, climate, vegetation, burned area, and spatial scale. The results indicate that warm semiarid watersheds respond differently to disturbance compared to colder watersheds, emphasizing the importance of considering the asynchrony between winter snowmelt and summer evaporative demand when assessing long-term impacts on water supply.

Summary: The Yellow River in China faces various emerging pressures, with water stress in the lower reach being the most concerning, primarily caused by reduced flow. Pollution and climate change also contribute to water stress. The study recommends the use of demand management approach and adaptive policy measures as alternative solutions to tackle the challenges presented by these emerging pressures.

Summary: Globally, the impacts of climate change can vary across different regions. This study evaluates recent and projected climate change in Europe using a probability framework. The results show that temperature has increased significantly, while changes in precipitation are not as consistent. The eastern and UK/Ireland regions are expected to experience the largest increase in temperature and precipitation extremes, respectively. The study also reveals that increases in precipitation extremes mainly occur at larger extremes.

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: Flash flood early warning requires accurate and timely rainfall forecasts. Radar rainfall nowcasting combined with numerical weather prediction (NWP) forecasts can be used to extend the lead time of short-term rainfall forecasts. In this study, an adaptive ensemble blending method was implemented to combine extrapolation nowcasts, NWP forecasts, and noise components with skill-dependent weights. The method was evaluated using heavy rainfall events in Belgian and Dutch catchments and compared with other forecast methods. The results showed that the blending approach performs similarly or better than only nowcasting and adds value compared to NWP for the first hours of the forecast.

Summary: Plastic pollution in urban rivers is influenced by hydrometeorological and anthropogenic factors. Tidal dynamics were found to be the main driver of plastic transport closest to the river mouth, while rainfall and river discharge were more important drivers outside the tidal zone. Long-term monitoring data is needed to further investigate the inconsistent correlations between plastic transport and hydrometeorological variables. The findings support the hypothesis that tidal dynamics are crucial in controlling the emissions of plastics from rivers into the ocean.

Summary: Catchment-scale plastic pollution assessments provide insights into the sources, sinks, and pathways of plastic pollution. We propose an approach to quantify macroplastic transport and density in the Odaw catchment, Ghana, and find that the urban riverine zone has the highest transport, while the urban tidal zone has the highest riverbank and land macroplastic density.

Summary: Controls on open water evaporation of a large lowland reservoir in the Netherlands were studied. Wind speed and vertical gradient of vapour pressure were found to be the main drivers of open water evaporation. Data-driven models using only two variables showed satisfactory results at some locations but not for others.

Summary: This study proposes a method to improve rainfall estimation using commercial microwave links (CMLs) by systematically calibrating all parameters of the algorithm. The stochastic particle swarm optimization method is used for parameter optimization. Results show that the proposed method improves rainfall estimation compared to the default parameter settings and performs even better when averaged over the entire Netherlands. The method is also of general interest for calibrating parameters in other climates and cellular communication networks.
