North Bintan District is one of the areas threatened by tidal flooding. Tidal flooding has disrupted socioeconomic activities in coastal areas. This can be identified as a factor in the emergence of maritime threats and national security. This study aims to identify the tidal characteristics of the North Bintan District. The method used is to apply the FNL data to the Delft3D model and use the TMD model and PUSHIDROSAL data to simulate the tide level during tidal floods in the coastal area of North Bintan District. Thresholds for each prediction method were obtained: PUSHIDROSAL is 2.6, TMD model is 0.3785, and TMD + MSL is 1.7925. The Delft3D model does not provide enough imagery to show the presence of sea water encroaching on coastal areas. The tides in North Bintan District are semi-diurnal, with high tides from morning to noon and low tides from afternoon to evening.
