    This Thesis mainly provides an overview of the methods used to predict the breach outflow hydrographs with a detailed case study of hypothetical breach failure of dam ‘Kaliasot Dam’ using HEC-RAS software. The parameters describing a breach are typically taken to be the breach depth, width, side slope and breach formation time. The process of gathering data and preparing data and analysis of unsteady flow model in HEC-RAS, entry of dam breach parameters, performing the failure analysis and flood mapping in ARC-GIS is discussed. Here the maximum discharge, velocity, elevation and top width is obtained to find out the villages that are going to be affected at the downstream side of Kaliasot dam upto 30 km. It is easy to estimate flood and flood routing but it is very difficult to estimate the cost of maintenance and safety precautions for the given dam.
