Numerical Study on Water and Sediment Environment of Artificial Island
Constructed in Stages in Longkou Bay
Abstract
Construction of large island is an important way to explore marine space resources and to
expand development space of China’S coastal cities．Uureasonable engineering construction
will lead to the reduction of natural coastline．the degradation of marine environment and other
issues．So studying the impacts of offshore artificial island construction in stages on marine
dynamic conditions and topography has important practical guiding significance for
construction scheme optimization．
This artical takes China’S largest offshore artificial island group consisted of Longkou
artificial islands and Zhaoyuan artificial islands which is being built in Longkou Bay as
research object，hydrodynamic and sediment mathematical model and water exchange
mathematical model in LongkOU bay nearby waters is set up by MIKE2 1 software．On the basis
of proven by the measured data,hydrodynamic and sediment changes in the condition of only
the Longkou artificial islands and four condition of Zhaoyuan artificial islands construction in
stages after longkou artificial islands and water exchange within the channels of overall
artificial islands are simulated and analyzed．We compared the schemes ofthe artificial islands
constructed in stages from the perspective of ocean dynamics and water exchange．The results
showed that in the construction of
