Development and optimization of an offshore hydrodynamic forecasting model

• Research Introduction：The application of executable shoreline restoration units in shoreline restoration and the exploration of the impact of the scale and spatial arrangement of natural shoreline restoration projects on the peak water level (PWL), the concept of executable ecological restoration units, "Operational Landscape Units" (OLUs), was introduced and applied to the east coast of China, especially to the western part of the inland shelf of the Yellow Sea ( WYS), where the nearshore is divided into 18 county and district level areas. The effects of OLUs on the peak water level of the WYS were quantified through 24 sets of numerical simulation experiments. The effects of OLUs at different locations and scales were simulated by setting up different shoreline restoration scenarios and compared with a fully hardened shoreline. The study shows that rationally located OLUs can effectively reduce coastal flood risk and provide new ideas for coastal protection and restoration programs.

Transport and transformation of offshore and nearshore materials (sediment particles, plastic debris, etc.)

• Research Introduction：Through the combination of physical modeling experiments and numerical simulation means, we study the movement law of near-shore materials under the action of near-shore waves, and their correlation to wave conditions and their own properties, and understand their transportation mechanism and near-shore process; based on the theoretical analysis and data-driven fusion to reach a rapid prediction of marine garbage and pollution traceability.
