| Abstract: | By using the method of combined numerical computation and experiential equations,the two dimensional model which describe the sediment transport caused by both wind and wave on the seabed is got in the paper.after that,the features of sediment transport with different wind speed,wind orientation and the sediment's diameter are discussed,we point out the proper cases in which the experiential equations could be used,and also the importance of wind speed and wind orientation of sediment transport,which is useful in the design of structures near shore. |
