The objectives of this study are to investigate the changes of runoff and sediment load and their potential influencing factors in the Huangfuchuan catchment.
The Mann-Kendall test and accumulative anomaly methods were, respectively, applied to examine the changing trends and abrupt changes.
Both annual runoff and sediment load demonstrated significant reduction ( p < 0.05 ) with decreasing rates of −3.2 × 106 m3/a and −1.09 Mt/a, respectively.
The abrupt changes were detected in 1979 and 1996 for the runoff and sediment load.
All the runoff and sediment indices (runoff, sediment load, runoff coefficient, and sediment concentration) exhibited remarkable reduction ( p < 0.01 ).
The climate variability contributed 24.4% and 25.1% during 1980–1996 and 1997–2010 to annual runoff decrease, respectively, and human activities accounted for the remaining 75.6% and 74.9%.
In contrast, changes in precipitation accounted for 43.5% and 20.2% of sediment load reduction during 1980–1996 and 1997–2010, whereas the human activities contributed 56.5% and 79.8%, respectively.
The relative contributions from climate variability and human activities to runoff and sediment load changes at annual scale were different from that at flood season scale.
Results suggested the dominant role of soil and water conservations in the variation of runoff and sediment load in the catchment.
