Are embankments a good flood control strategy? A case study on the Kosi river
Whether embankments should be used to control floods is a question of great importance in the eastern Gangetic plain, where embankment breaches cause severe flood damage every year and huge damage due to major breaches every few years. Critics of the embankment policy have called for a strategy of living with floods by building dispersed infrastructure to cope with floods. However, no cost–benefit analysis of alternative strategies is available. This paper makes a first pass at evaluating embankments.
