A natural hazard like flood is being an integral part of civilization since ages, turning out to be a disaster for society. It results in damage to human life, deterioration of environment and infrastructure facilities through inundation of low lying areas. In some of the last decades frequent flooding condition have been generated in Ambica river and major flood event has occurred in the years of 1981, 1984, 1994, 1997, 2001, 2003, 2004, 2006, 2013 & 2014. However Navsari city is located at the bank of river Ambica, which is being frequently affected by floods and the maximum discharge, was observed at Gadat i.e. 2989 cumec in the year 2004. In order to know the submergence of area in nearby location of Ambica River due to extreme flood, present study aims to prepare a 1D-Hydrodynamic model by using HEC-RAS. This model will analyse the steady flow of river in 1D and based on this study it is strongly recommended to construct flood wall or either increase the height of the existing wall at a particular cross-section.
