英文摘要Study region: Wuding River catchment, the wind-water erosion crisscross region on the Chinese Loess Plateau.Study focus: The wind-water erosion crisscross region suffers severe soil erosion in the world, and various catchment properties control fluvial processes. This study investigated suspended sediment (SS) transport characteristics in a typical catchment with two geomorphological types (aeolian sand and loess hilly). Lorenz curves and partial least-squares regression were used to quantify the SS transport characteristics and attributions. New hydrological insights for the region:There were significant differences in the SS transport characteristics between the two geomorphological regions. In the aeolian sand region, the mean annual SS loads were much lower than that in the loess hilly region (P < 0.01) under similar precipitation and runoff conditions. Rivers in this region transported SS all year round. The relatively lower concentration indicated that extreme events did not dominate total SS load. Conversely, SS transport in the loess hilly region was highly concentrated during a few events in rainy season, with the largest 10% of the events transporting exceed 80% of the total SS load. Statistical analysis showed that drainage density, catchment slope, and soil texture were the dominant factors controlling SS load, while the concentration of SS transport events was more related to the perimeter-area fractal. These findings have important implications for fluvial sediment transport in arid and semi-arid environments.
