Flood is a natural disaster that often occurs in Bone Bolango Regency, Gorontalo Province during the rainy season. There are some areas always flooded but there are also new areas affected by floods so that citizens and local governments were unprepared for the disaster. This caused a great impact and losses including flooded settlements, destruction of agricultural land, damage to infrastructure, significantly disrupt economic activity, and the impact on public health. This study aims to identify flood prone areas for natural disaster mitigation using geospatial approach in Bone Bolango Regency, Gorontalo Province. This research integrates geospatial data analysis including topography, rainfall data, mapping of land cover and field survey. This research is very important for disaster risk reduction. The results show that generally flood-prone areas are distributed in low land, around major river flows both in the middle and downstream of rivers, landform of floodplains and alluvial plains, and generally in areas with extensive settlements and farmland. © Published under licence by IOP Publishing Ltd.
