This study evaluates the flood hazard index in Kuala Langsa Village, City, Aceh, a region prone to frequent flooding due its low-lying coastal location eastern Aceh. It serves as crucial link between North Sumatra and Aceh provinces. The area's significance underscores importance of understanding mitigating risks. By utilizing coupled 1D/2D Hydraulic model, hazards are accurately predicted mapped. field data collection (as calibration) measures maximum tidal water level based on information from residents affected by land surface under their houses. Hydrological conditions during December 2017 event simulated using HEC-HMS. evaluated HEC-RAS 6.4.1. research aims assess Village spring tide conditions, considering variations base flow with return periods 2 50 years upstream. main results show that an FHI >2.62 (high) covers area 169.74 ha, 2.62 > >2.23 (moderate) encompasses 172.60 <2.23 (low) accounts for 222.32 ha. During Q50 upstream flood, there was increase extent: low 61.20 %, medium 25.32 high 5.57 %. These findings deepen our estuary mechanisms emphasize developing more effective adaptation strategies reduce risks future.
