Climate vs. Human Impact: Quantitative and Qualitative Assessment of Streamflow Variation

This paper presents a novel framework comprising analytical, hydrological, and remote sensing techniques to separate the impacts of climate variation regional human activities on streamflow changes in Karkheh River basin (KRB) western Iran. To investigate type changes, recently developed DBEST algorithm was used provide better view underlying reasons. The Budyko method HBV model were decreasing streamflow, detected non-abrupt change trend, indicating activity region. Remote analysis confirmed this finding by distinguishing land-use found an abrupt precipitation, reflecting streamflow. final assessment showed that observed reduction is associated with both influence. combination increased irrigated area (from 9 19% total area), forests 11 3%), annual precipitation has substantially reduced rate basin. can be implemented other regions thoroughly vs. hydrological cycle, particularly where data availability challenge.
