Abstract
In order to quantitatively evaluate the impact on local hydrodynamic environment and sediment transport characteristics by sea area dredging works east to Sandun Highway in Qinzhou Bay,the sediment transport characteristics under wave-current coupling was studied by using 2D plane mathematical model.On the premise of reliable calculation results,a research was carried out for the impact of dredging engineering sea area on the distribution of flow characteristics,the change of tidal accommodating capacity and annual siltation volume after the construction had been completed.The analysis results show that the dredging works will lead to the average decrease in sea current velocity in the engineering sea area by 4～8 cm/s,and the decrease in local flow velocity by 30 cm/s,but only a little increase in tidal accommodating capacity in the region by 0.065%.The decrease of flow velocity resulting from dredging may produce siltation in most of engineering sea area,with the average silting intensity of 2～4 cm/a,and inshore silting intensity of 8～10 cm/a.In addition,an increased flow velocity in local sea area may lead to the intensity of scouring at 1～2 cm/a.关键词
