Understanding the role of land cover changes on climate and hydrology during typhoon events is vital for coastal hazard mitigation, prevention, as well as the regulation of land cover. To investigate the effects of land cover changes, simulation studies using the WRF model to calculate the meteorological field combined with the Delft3D-FLOW model capable of accurately simulating storm surges were conducted. The accuracy of this modeling approach is guaranteed since the models were validated against available in-situ and satellite measurements during typhoon Rammasun (2014) period. Through comparing simulation results obtained with the MODIS 2001 and the GlobCover 2009 land cover data scenarios, it is found that land cover changes in the study region exert an apparent influence on the atmospheric and storm surge simulations. Notable disagreements exist between the selected two land cover data. Different types of land cover have disparate physical properties, such as roughness length that alters the typhoon-induced wind field simulation results, thus resulting in changes in storm surge simulation results. Determining the impact of land cover changes on atmosphere and storm surge provides clearer insight into the land cover impacts, which is of great benefit to the atmospheric and storm surge models improvement.
