Reclamation of marine can lead to many negative effects, such as the decreased space tide, disappeared
beach, lost wave energy dissipation space, increased influx of disaster risks and filled up riverbed. And in
the meanwhile, flow outside the channel slows down, seawater purification declines, frequency and
intensity of alga bloom increase. Reclamation materials and pollutants generate during the reclamation
activities and they can pollute the marine environment. In addition, the beach and barrier disappear, the
impact of waves on coastal areas will be further increased, and the phenomenon of seawater intrusion will
be increased in sequence [4]. Reclamation of marine, causing shoreline change, has also affected the
deposition of modern sediments [5, 6].
