# Kisumu Flood Risk Dashboard An interactive tool showing real, sourced flood exposure data for all 35 wards in Kisumu County, Kenya. ## What it does For each ward, this dashboard shows: - Total population - Building count - Flood hazard area (% of ward at risk, 50-year return period) - Estimated population and households at risk - Estimated financial exposure (based on standard humanitarian cost estimates) An interactive map visualizes flood risk across all wards. ## Data sources - **Population**: WorldPop 2020 constrained population estimates (data.worldpop.org) - **Ward boundaries**: HDX / American Red Cross, "Administrative Wards in Kenya 1450" - **Buildings**: OpenStreetMap (via OSMnx) - **Flood hazard**: JRC (EU Joint Research Centre) Global River Flood Hazard Maps, 50-year return period ## Notes - Building data is complete for 30 of 35 wards; the remaining 5 are marked as pending due to data source limitations, not estimated. - Financial exposure uses a standard humanitarian planning assumption of $10/person/day over a 14-day disruption window — this is a stated estimate, not an audited figure. ## Author Teresia Kinuthia, Maseno University, School of Planning — Disaster Management with IT
