Hydrological response to compounding impacts of climate change and forest management in the upper Kings River basin, CA, USA

In the western United States, the Sierra Nevada region experienced decades of fire suppression-driven changes in forest structure and composition, resulting in increased vulnerability to drought, water stress, tree mortality, and exposure to severe wildfires. Sierra Nevada’s watersheds and forests are predicted to undergo warmer and drier conditions due to climate change, making them even more vulnerable to disturbances. Restoring forests by reducing forest density and fuel accumulation has the potential to improve forest resilience to droughts and climate change, increase water availability, and provide other ecosystem benefits. In this study, we investigated the individual and compounding effects of forest treatments on evapotranspiration and streamflow in the upper Kings River basin under different warming scenarios using the SWAT+ model. We simulated large-scale forest treatments throughout the landscape to evaluate the hydrological response to warming across a water-energy gradient..., , # Hydrological response to compounding impacts of climate change and forest management in the upper Kings River basin, CA, USA

## Description of the data and file structure

These datasets are based on SWAT+ simulations conducted in the Upper Kings River Basin, California, USA. The datasets range from daily to monthly and water year periods, and are spatially aggregated from HRU and LSU components to characteristic hillslopes and the full basin. The datasets are in the R data format (\"*.Rda\").

美国西部内华达山脉（Sierra Nevada）地区历经数十年受火灾管控驱动的森林结构与组成变迁，致使其对干旱、水分胁迫、树木死亡及重度野火的脆弱性显著提升。受气候变化影响，内华达山脉的流域与森林预计将呈现更暖更干燥的环境特征，进一步加剧其受干扰的风险。通过降低森林密度、减少可燃物堆积开展森林恢复工作，有望提升森林对干旱与气候变化的恢复力，增加水资源可获得性，并带来其他生态系统效益。本研究借助SWAT+模型，在不同增温情景下，探究了森林管理措施对美国加利福尼亚州国王河上游流域蒸散发与径流量的单独及复合影响。我们在全景观尺度上模拟了大规模森林管理措施，以评估水-能量梯度下增温引发的水文响应...
