Bihar, once ravaged annually by the relentless floods from the Kosi River, has undergone a remarkable transformation, with the World Bank-supported Bihar Kosi Basin Development project. The strategic fortification of spurs and embankments helped protect infrastructure and enabled communities to flourish along the riverbanks. The new Flood Management Improvement Support Centre, established under the Project, is using innovative technology to gather data, and uses simulation to forecast flood warnings. This is helping the state to be better prepared and better manage its agriculture, infrastructure, education, and healthcare. This project provides a holistic model for effective flood management and offers insightful learnings for regions facing similar challenges.
