The Kuye River basin has seen a significant decrease in runoff and sediment discharge since the 1960s, despite no major changes in precipitation levels. This suggests that human activities, not just rainfall, are responsible for the decline in water resources in the region. The relationship between precipitation and water flow has shifted over time, with less runoff and sediment discharge occurring even with the same amount of rainfall. This indicates that the impact of human activities on water resources in the Kuye River basin is substantial and needs to be addressed to ensure sustainable development and environmental health in the area.
