| Abstract: | A seabed siltation calculation formula is established by using the balaced sediment concentration,and thus a new concept of seabed siltation index is derived and a discriminant of seabed siltration is obtained to predict the evolution trend of seabed siltration.The tidal hydro-geological test data for Yangshan Port area collected by Shanghai International Shipping Center is further used to calculate the seabed siltation index and predict the seabed siltation trend.The predicted result is exactly consistent ... |
