Coastal seabed disposal is one of the repository options isolating high-level radioactive wastes (HLW) from human. HLW under seabed sediments would be covered by the various layers of the sediments. The aim of this research is to construct a coastal model for the transport of radionuclides from HLW disposed beneath seabed to the surface of the sediments.
