| Abstract: |
| To scientifically analyze the effect of offshore wind farm on intertidal beach stability, this paper summarized the research progress of intertidal zone dynamic change analysis at home and abroad. The method of hypothetical sandbank surface discrimination (HSSD) was proposed. The topographic changes that caused by offshore wind turbine construction in intertidal zone were estimated quantitatively from single phase DEM, the contribution rate and contribution mode of the erosion and deposition change of offshore sand body terrain offshore caused by wind turbine construction and operation were analyzed. The multi temporal intertidal zone DEM was based on enhanced waterline method (EWM). It carried out the quantitative assessment of the safety and stability of offshore wind turbines due to the change of intertidal tidal flat erosion and deposition. The practical application proved that the scheme could be used for the influence of offshore wind turbines on intertidal zone topographic changes with quantitative remote sensing monitoring. |
