River regulation and resilience: an approach for the Yangtze watershed

Many studies have focused on analyzing variation characteristics of the watershed resilience based on different indicators, while few efforts have been made to quantificationally evaluate contributions of climatic and anthropogenic factors to the varied resilience. In this study, we investigate chan...
