Quantitative Analysis of the Interaction between Wind Turbines and Topography Change in Intertidal Wind Farms by Remote Sensing

Offshore wind farms have developed rapidly in Jiangsu Province, China, over the last decade. The existence of offshore turbines will inevitably impact hydrological and sedimentary environments. In this paper, a digital elevation model (DEM) intertidal sandbank southern Province from 2018 to 2020 was constructed based on improved remote sensing waterline method. On basis, stability analysed, combined with hypothetical surface discrimination method (HSSDM), erosional/depositional influences turbine construction topography were quantitatively analysed. results show that due frequent oscillations tidal channels, only 35.03% study area has stable topography, more than 90% all years balanced intensity topographic change, see small reduction their following year. remaining impacts are mainly located areas unstable but overall is 2018–2020. both erosional depositional, not significant. This demonstrates quantitative effects provides some help for site selection monitoring after completion.
