Research Institutes

Institute of Port,Coastal and Offshore Engineering


The Institute of Port, Coastal, and Offshore Engineering was founded in 1998 and merged into the Department of Ocean Science and Engineering in 2009. The institute offers two PhD programs -- Port, Coastal, and Offshore Engineering and Marine Structures and Environment, and shares a post-doctoral program in Hydraulic Engineering.
The institute has 10 faculty members, including 2 professors, 6 associate professors, and 2 research scientists. The institute also has 6 adjunct scientists including four academicians of the Chinese Academy of Engineering -- Prof. Jilan SU, Prof. Jiyu CHEN, Prof. Yingchen LIAN, and Prof. Delu PAN and two members of Special Expert of Zhejiang Province -- Prof. Yincan YE, and Prof. Huanting SHEN.
Research Areas
1) Port and waterway planning and regulation
Research in this area focuses on the location selection for deep water port and waterway, port and waterway planning, comprehensive planning of estuaries, channel and waterway regulation, flood control safety, water resources optimal allocation, and application of GIS.
2) Estuarine and coastal numerical modeling
Numerical models of tidal flow and sediment transport can be used to simulate hydrodynamics, such as tides, currents, waves, long-shore currents, and storm surge, and transport of sediment and pollution in tidal estuaries and coast zones. The models are useful tools for the planning, design, construction, and management of marine engineering projects, including port construction, waterway dredging, wetland reclamation, cross-sea bridge, offshore platform, underwater tunnel, submerged pipeline, and coast protection. Environmental impact of these projects can also be evaluated by the models, which serves as a scientific basis for government decision making.
3) Sediment transport, river and coastal dynamics
Research focuses on theories of sediment erosion, transport and deposit by fluids in estuarine and marine environments to understand the mechanism and process of landform evolution of estuaries, coast zone and seabed. The topics include incipient motion of cohesive non-uniform sediment, bed-load transport, seabed erosion and fine sediment suspension, the non-uniform sediment equilibrium concentration formula, sized bed-load formula and the probability of cohesive non-uniform sediment motion based on both hydrodynamic and probability theories. A new model considering the interaction between particle and turbulence based on solid--liquid two phases flow theory and the bed-load differential equations of sediment motion has been developed in the institute. Other related fields such as the characteristics of fine sediment in Yangtze River, the causes of turbidity maximum in estuary, and the mechanism of formation of a delta estuary are also studied.
