Like many rivers across the world, the Nzoia River in western Kenya pushes over its banks each year. For example, in November 2008, the river burst through the dikes, flooding the low-lying land around it. According to the United Nations Office for the Coordination of Humanitarian Affairs, at least 5,000 people were marooned or evacuated from the banks of the swollen river. The SERVIR Flood Map Tool, which was co-developed by the SERVIR Applied Sciences Team and the SERVIR-E&SA hub, has been used to identify sections of the dikes that needed repair. Based on this information, the World Bank’s Water Security and Resilience Project provided financial assistance to design and implement the repairs.
