Summary: Our research indicates that using predictors such as soil moisture, SWE, and precipitation can lead to extended seasonal predictions of the UCRB streamflow. Additionally, incorporating Pacific SST information can improve the prediction skills for lead times between 6 to 9 months.

Summary: The ongoing drought in the Upper Colorado River Basin has been found to be extremely severe, especially when compared to the tree-ring records from as early as 762 CE. Using gridded drought-atlas data and streamflow data, researchers have developed a streamflow reconstruction model for the Lees Ferry gage, revealing a second-century drought that surpasses the severity of the current drought and documented medieval period droughts. Limited data also support the occurrence of this exceptional second-century drought through analysis of individual tree-ring records and other paleoclimatic data.

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: The Adige River Basin plays a crucial role in providing water for agriculture, energy, and municipal supply. This study uses the Old World Drought Atlas dataset to reconstruct the streamflow in the upper ARB and identifies multiple drought and pluvial periods that exceed those observed in historical records.

Summary: The study utilized a macroscale hydrology model and an atmospheric river catalog to evaluate snow accumulation in the Upper Colorado River basin affected by atmospheric rivers. It was found that most atmospheric rivers affecting UCRB first pass through the Sierra Nevada region, resulting in greater snow accumulation there.

Summary: The study found that in the upper Colorado River basin, the annual trend of runoff in March is more statistically significant than in other months. The decrease in cloud optical depth may lead to reduced precipitation and increased temperature in March, resulting in a reduction of available water resources.

Summary: This study assesses the hydrological responses of land cover changes in the Muger watershed from 1986 to 2020. The key findings are that changes in cultivation land, forest land, and settlement have significant impacts on the hydrological processes. The study outcome can assist decision-makers and planners in preparing adaptable strategies under changing land cover conditions within a watershed.

Summary: Continued climate warming is reducing seasonal snowpacks in the western United States, affecting streamflow generation and water availability. Understanding the current and future spatiotemporal distributions of snowpack and surface water input is crucial for adapting to future conditions in snow-dominated regions.

Summary: This study examines a 30-year-old flow program on the Upper Arkansas River in Colorado to understand its impacts and adaptations to climate change. The program has been successful in achieving its goals, but is challenged by earlier spring runoff and reduced stream flows. Social learning and collaboration dynamics enable the participants to adapt through proactive communication and compromise over constrained flows. The study discusses these adaptations and raises questions about the future of the program.

Summary: This study collaborated with a water resource management community in the Upper Colorado River Basin to develop future drought scenarios and assess impacts on water supply reliability. Using a statistical model, the study evaluated reductions in water year streamflow and runoff efficiency due to temperature increases, providing insights for resource management.

Summary: This study provides estimates of projected baseflow changes in the Upper Colorado River Basin under different climatic conditions, showing potential declines in total baseflow supplied to the Lower Colorado River Basin, with a possible increase under warm/wet conditions. Additionally, the results highlight the impacts of climate-driven changes in high-elevation hydrology on basinwide water availability.

Summary: The Sava River Basin extends across six countries and is a major tributary of the Danube River. In the past 20 years, multiple hydropower facilities have been constructed on the Sava River to support Slovenia's initiative for clean energy. Studying past drought and pluvial periods in the river basin can provide valuable information for water managers and planners.

Summary: Water is a critical resource with significant challenges in the western United States. The National Oceanic and Atmospheric Administration has deployed environmental sensors in Colorado to understand the physical processes of mountain precipitation and streamflow. These sensors provide detailed information on spatiotemporal variability and support improved weather and water prediction.

Summary: The study found significant changes in water yield in the Upper Brahmaputra River basin during 1982-2013, mainly influenced by climate and cryosphere, with minimal impact from vegetation. Decreased precipitation in recent years has led to a decrease in water yield, but meltwater may alleviate water shortages.

Summary: This study provides extended seasonal predictions for UCRB spring precipitation using an ANN model and a linear regression model. The study finds that the extratropical North Pacific has a higher correlation with UCRB spring precipitation. The prediction models have high correlation coefficients (>0.45), low errors (<20%), and good skill scores (>50%).
