Geospatial analysis of Floods in Nairobi County
This report presents a comprehensive geospatial analysis of flood risk in Nairobi County, Kenya. Using proximity-weighted risk modelling, multi-factor susceptibility analysis, and seasonal prediction techniques, the study identifies and quantifies flood-prone areas across the city. The findings confirm that informal settlements along river corridors — particularly Mathare, Kibera, and Mukuru — face the highest and most persistent flood risk, driven by a combination of hydrological, topographic, infrastructural, and socio-economic factors.
