We analyze 4000-year flood history of the lower Yellow River and the history of agricultural development in the middle river by investigating historical writings and quantitative time series data of environmental changes in the river basin. Flood dynamics are characterized by positive feedback loops, critical thresholds of natural processes, and abrupt transitions caused by socio-economic factors. Technological and organizational innovations were dominant driving forces of the flood history. The popularization of iron plows and embankment of the lower river in the 4th century BC initiated a positive feedback loop on levee breaches. The strength of the feedback loop was enhanced by farming of coarse-sediment producing areas, steep hillslope cultivation, and a new river management paradigm, and finally pushed the flood frequency to its climax in the seventeenth century. The co-evolution of river dynamics and Chinese society is remarkable, especially farming and soil erosion in the middle river, and central authority and river management in the lower river.

“…As a case study, the headwater catchments of the Loess Plateau appear to be the main contributors to the high concentration of sediment in the Yellow River (Xu and Cheng, 2002;Liu et al, 2008). Anthropogenic activities, such as revegetation, check-dam construction, and the development of terraced farmland, have caused considerable shifts in the landscape pattern (Wang et al, 2007;Xin et al, 2008) and low sediment export to the sinks of the Nianzhuang catchment shows that landscape patterns effectively control sediment discharge.…”

“…Thus, such activities ultimately cut-off or weaken sedimentological connectivity. Xu and Cheng (2002) concluded that sediment production from the coarse-sediment producing area of the Yellow River, which is part of the Loess Plateau, contributes considerably to the sediment flux of the Yellow River. However, because of anthropogenic intervention (dam construction, revegetation) the sediment fluxes from the headwater catchments to the Yellow River have been cut-off or limited, as has been shown in this study.…”

a b s t r a c tSedimentological connectivity is an important issue in soil erosion and sediment transport. Landscape patterns, in combination with the rainfall regime, are known to shape such sedimentological connectivity. The quantification of sedimentological connectivity provides a link between sediment delivery and landscape pattern. There are two categories of connectivity: structural connectivity, which describes the physical coupling of landscape units, and functional connectivity, which delineates the linkage among landscape elements maintained by material transport. To quantify sedimentological connectivity, both the physical coupling of, and material transfer between, the various landscape components need to be assessed. This study quantifies the sedimentological connectivity of a headwater catchment in the Loess Plateau of China using the soil erosion and sediment delivery model (WATEM/SEDEM). Based on the model, two indicators of connectivity were developed: the area of sedimentologically effective catchment area (SEA) that contributes sediment to the sinks, and the minimum sediment output of locations on the flow path that link sources and sinks. This approach effectively represents the annual status of catchment-scale sedimentological connectivity and, furthermore, the simple structure and readily available input data make it highly practicable. However, for larger river systems in which sediment transport between sources and sinks occur over longer time scales and larger spatial scales, we suggest different techniques for quantifying the sediment flux and parameters delineating the physical coupling of landscape units.

ABSTRACT. The amount of the sediment deposition in the Yichan-Wuhan reach of the middle Yangtze River (also known as Changjiang River) has been determined using the concept of sediment budget at the channel-reach scale. The fill-scour processes of the middle Yangtze River were studied during the period 1956-1997 in response to the variation in sediment load and flow inputs. The results show that 13.3% of the net input of sediment was deposited in the studied river reach. Since 1956, the output sediment load of the studied reach increased with time to 1981, followed by a decline. The increase in output before 1981 can be related to the man-made bend neck-cutoff which caused a decrease in the sediment load diverted through the 'three outfalls' (i.e. the three distributaries from the Yangtze main stem to the Dongting Lake) and increased the sediment-carrying capacity of the river. Thereby, the river could transport more sediment to the outlet of the studied river reach. The decrease in the sediment load output after 1984 was directly due to the decreased sediment load at Yichang station. Multiple regression equations have been established to assess the contributions of influencing factors to the variation in sediment deposition amount in the studied river reach.
