Abstract:
In view of mountainous river characteristics, the effect of sediment concentration,flow and diameter to sediment deposition transmission were studied by variable and steep slope flume with single-factor controlling theory in this paper. The results showed that due to the slope becoming gentle ,sediment would be deposited in the middle or lower reach firstly,the higher sediment concentration, the lower flow or the larger diameter was, the faster speed of sediment deposition transmission would be. At the same time, the speed was also related to slope of flume .The steeper the slope was ,the faster the speed would also be.
