Dams all around the world play a very important role in the economy of a country through providing benefits like controlling floods, providing water for irrigation, hydropower generation, drinking water, recreation among other benefits. However, in the unlikely event of failure, dam failures can result into catastrophic flooding in the downstream area which may result in huge loss of human life and property. The loss of life would vary with extent of inundation area, size of the population at risk, and amount of warning time available. In order to develop a breach hydrograph that can be routed downstream to determine flood inundation, flood wave arrival timing and ultimate consequences, parametric equations and guidelines for breach parameters were used to build the model.
