Abstract


Bolo Sub-district, Bima Regency, West Nusa Tenggara, is highly vulnerable to flooding due to hydrological factors and lowland topography. This study maps flood-prone areas using Geographic Information Systems (GIS) with scoring and weighting methods on five parameters: rainfall, slope gradient, soil type, land use, and river buffer zones. Results show that 46.65 km² (59.90%) is very vulnerable, 17.22 km² (22.11%) is vulnerable, and 14.01 km² (17.99%) is safe. The flood-prone area totals 70.76 km² or 93.52% of the sub-district. Key factors include 0–8% slopes, dryland agriculture, Chromic Luvisols soil, and proximity to rivers (0–25 m). This study supports GIS-based flood risk mapping and serves as a reference for further civil engineering research.
