Research Interests:

Sealevel;            Delta;           Sub-bottom Profiling;        Sediment Transport Modeling


  •        Late  Quaternary sea-level changes and their paleo-climatic  and paleo-environmental implications;
  •        Flux and fate of river-derived sediment in the marginal sea.  Riverine sediment dispersal, transport, and accumulation in different continental margin environments, in particular those deltaic and clinoform deposits from the large rivers in Asia, e.g. Yellow, Yangtze, Pearl, Red, and Mekong rivers, etc;
  •     Nearshore and Offshore Seafloor Mapping using high-resolution Subbottom Profiler (Chirp Sonar) and Swath Bathymetric Sonar System.

  •     Sediment Transport Modeling using Delft3D and ROMS-Sed.
  •  Using watershed GIS tools for best assessment of landuse, water quality, sediment budget, total maximum daily load (TMDL), coast and barrier islands protection and development.
