Transformation of the sediment concentration space-time distribution along Loess Slope
The transformation of the sediment concentration space-time distribution along loess slope was analyzed under different water discharge amount on loess slope in hydraulic research base of Yellow River Institute of Hydraulic Research. The observation data showed that: the sediment concentration along slope were increasing gradually with the flow path prolong at 3L/min water drainage on 20°slope, the sediment concentration at different section arrive oscillating stability when the experiment continue 20mins. and then the sediment concentration of Sth section was about 0.65g/cm3, it was 1.5 times to the sediment concentration of 3rd or 4th section, it was 2 and 2.5 times to the sediment concentration of 2nd and lst section; the sediment concentration along slope were increasing gradually with the flow path prolong at SL/min water drainage on 20°slope, the sediment concentration of 4th and Sth section were about 0.63g/cm3, it was 1.2/1. 1/1.6 times to the sediment concentration of 3rd/2nd/lst section when the slope sediment concentration arrive oscillating stability; the sediment concentration along slope were increasing gradually with the flow path prolong at 7.5L/min water drainage on 20°slope, the sediment concentration of 4th and Sth section were about 0.60g/cm3, it was 1.2 times to the sediment concentration of 3rd and 2nd section. it was 1.3 times to the sediment concentration of lst section when the slope sediment concentration arrive oscillating stability.
