Definition of Ratio of Bed-suspended Load from Sediment Movement Along Powder Sandy Coasts |
| |
| Abstract: | A method is proposed for calculating the bed suspended load ratio of transport rate both uniform and non uniform sand in coast sediment movement as well as for calculating that of channel deposition.It's shown from the numerical calculation that bed load and suspended load along the powder sandy coast should be considered at the same time,and the calculated results are in a good agreement with the flume test. |
