The Kuye River in the Yellow River basin experienced decreasing runoff and sediment due to both climate change and human activities. By analyzing data from 1960 to 2014, researchers found that human activities were the main reason for these changes. Using a combination of hydrologic models and machine learning algorithms, they determined that climate change contributed 24%-39% to runoff reduction and 15%-36% to sediment reduction, while human activities accounted for 61%-76% of runoff reduction and 64%-85% of sediment reduction. This study provides valuable insights for managing water resources and preserving sediment in the Yellow River basin.
