Influence of Huanghua harbor dredged construction on channel siltation

According to the sediment movement characteristic of silt-sandy beach and features of siltation during navigation construction period,the relationship between dredging volume,dumping volume and land form transition is analyzed and the relational expression is established.Using field measurement data of Huanghua harbor,the coefficient of the formula is defined,and the construction siltation,regular siltation quantity and other affected factors are analyzed.Then the coefficient of siltation affected by disposal during navigation construction period is obtained.Regular siltation and windy energy correspond fairly well.
