Engineering 2019, Volume 5, Issue 5,   Pages 855-864 doi: 10.1016/j.eng.2019.07.014

Abstract: Loess Plateau is the most seriously eroded area in the world and contributes the vast majority of the sedimentHowever, the mechanism
of the sediment transport dynamics is not fully understood due to multipleA challenging question, then, arises: Is the current low sediment level a "new normal" in thisfrom low discharge and a potential higher sediment load resulting from large discharge.of a large sediment load during extremely wet years.

Red soil for sediment capping to control the internal nutrient release under flow conditions

Lei Xia, Guo Liu, Chunmei Chen, Meiyan Wen, Yangyang Gao

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 6, doi: 10.1007/s11783-016-0886-2

Abstract: The inhibition of sediment nitrogen (N) and phosphorus (P) release seems necessary.Red soil (RS) was firstly used as sediment capping material under flow conditions.RS capping can effectively reduce the N and P release from sediment.Nitrogen (N) and phosphorus (P) released from the sediment to the surface water is a major source ofTherefore, inhibiting sediment nutrient release seems necessary.
