Based on the MK test and RUSLE model, changes in the soil erosion and sediment yield of the Xiliugou basin in the upper Yellow River during the period 1960–2013 were studied. The results indicate that hyperconcentrated floods are very typical in the Xiliugou basin. Hyperconcentrated floods occurred in 87.1% of the years during the period 1960–1990. Since the 2000s, the number of such floods was reduced...
The spatio-temporal variation underlies and complicates studies related to earth surface processes. Subsequent to our previous studies reporting the temporal invariability of sediment concentration, this study further reports the spatial invariability of sediment concentration or the flow–sediment relationship in the hilly part of the Chinese Loess Plateau. The dense channel network dissects this...
Little information is available on the scale behavior of the flow–sediment relationship despite numerous studies on the scale behavior of sediment yield. Based on data observed at 19 gauging stations and 10 runoff experimental plots, we examined the flow–sediment relationship in the context of spatio‐temporal scales for hilly loess areas, China. Distinct from many rivers around the world, sediment...
The spatial scale effect on sediment concentration in runoff has received little attention despite numerous studies on sediment yield or sediment delivery ratio in the context of multiple spatial scales. We have addressed this issue for hilly areas of the Loess Plateau, north China where fluvial processes are mainly dominated by hyperconcentrated flows. The data on 717 flow events observed at 17 gauging...
