Flooding is the major environmental disaster in Jigawa State. It occurs annually, causing serious damages to lives and properties. This research identified areas vulnerable to flood using Geospatial techniques, especially, AHP model of MCE and suggests how to minimize its impacts. Questionnaires were administered to six experts from Hadejia Jama'are River Basin Development Authority on flood causative factors. The AHP model revealed that rainfall (22.49%) was the highest contributor to flood, followed by slope (22.22%), drainage density (21.894%), land use/land cover (12.51%), distance from river (11.21%), and soil type (9.67%). Based on the flood frequency analysis using Gumbel distribution for return periods of 5yrs, 10yrs, 25yrs, 50yrs and 100yrs; the expected discharges obtained were: 523.5 m3/s, 523.8 m3/s, 524.0 m3/s, 524.1 m3/s, 524.2 1 m3/s, 524.3 m3/s and 524.7 m3/s respectively. There were no significant changes in the computation of the discharge at Challawa Dam for return period of 5–30 years, but there is a significant change from 50 to 100 years return period. Flood vulnerability map was generated based on flood causative factors. Parts of Ringim, Jahun, Taura, Miga, Auyo, Kiri-Kasamma, Hadejia, Kafin-Hausa and Kiyawa were highly vulnerable to floods, while Birniwa, Malam-Madori, Maigatari Gumel, Kaugama, Gagarawa and Guri have very low vulnerability. The flood vulnerability map will help the state to understand the factors causing floods. It can also assist decision makers for flood assessments, prediction, adaptation and mitigation. The research recommends adequate flood control mechanisms; building temporary water ponds along the Hadejia Jama'are River to redirect excess water to the ponds; proper enlightenment campaigns in vulnerable areas; preventive and mitigation action in Ringim, Jahun, Taura, Miga, Auyo, Kiri Kasamma, Hadejia, Kafin Hausa and Kiyawa and establish Flood Early Warning System for the state.
