Flash flood hazards from heavy rainstorms are common in Hieu catchment (Nghe An province). This study presents a flash flood hazard assessment for Hieu catchment using the combination of Analytic Hierarchy Process (AHP) and Geographic Information System (GIS). A total of seven parameters to control flash flood occurrence were calculated using AHP and overlaid in GIS. Flash flood risk hazard map of Hieu catchment is divided into five risk levels: very high (2.01%), high (20.32%), medium (43.78%), low (30.59%), very low (3.3%). A hazard map was produced to help local authorities implement land use planning that reflects the hazards, and prepare to increase disaster response capacity to human and environmental resilience to flash floods.
