Hydrodynamics and sediment transport on tidal flats of Incheon, Korea

Tidal flats of Incheon, Korea are located off the coast of the Han River mouth. The extensive macrotidal mud flats, on which tidal range exceeds 9 m, are unique in that freshwater discharge during the summer wet season influences the region, while strong waves dominate resuspension and transport processes during winter. A field campaign has been initiated to better understand imparting influences of these processes. A benthic pod was deployed on the southern coast of Gangwha Island. Instrumentation on the pod includes one ADV, one ADCP, one ABS, two OBSs, and one rotating side-scan sonar. We describe flow, sediment transport and morphodynamic processes on a macro-tidal environment.
