- Erosion caused by hyperconcentrated flow on the Loess Plateau of China (1)
- Historical bank-breachings of the lower Yellow River as influenced by drainage basin factors (1)
- Hyperconcentrated flows in the slope-channel systems in gullied hilly areas on the Loess Plateau, China (1)
- Precipitation-vegetation coupling and its influence on erosion on the Loess Plateau, China (1)
- Using data from some Chinese rivers, an attempt has been made to express quantitavely, by using statistical methods, the connections between river channel pattern characteristics and the corresponding river bed material grain size parameters.
- erosion and sediment production processes. There exists a strong coupling relation between hyperconcentrated flow transport and gravitational erosion, which ensures a rapid removal of mass-wasted materials. Some countermeasures are proposed to control
- Based on data from the Loess Plateau of China, some non-linear relationships between forest cover, mean annual rainfall erosivity and annual precipitation have been found. A threshold has been identified. Furthermore, 2 thresholds are identified
- basin. Consequently, some corelations have been established. Human activities are the major factor influencing sediment-related disasters in the Yellow River.
- that the formation of hyperconcentrated flows is closely related to the vertical differenciation of landforms. A close relationship is found between rainstorms and the formation of hyperconcentrated flows, and some thresholds of rainfall and runoff for the occurrence
