Abstract: As there have been hazardous climatic environments due to climate variation and as a consequence, the intensity of rainfall has increased tremendously causing floods in India. Floods are the most critical among all the natural calamities in world causing vast damages to life and property. It is therefore essential to address these natural calamities by developing integrated approach for the flood modelling and flood mapping for future prevention of flood and to decrease the influence on societies and life and the surroundings. For hydraulic modelling and floodplain mapping was integrated to perform flood routing for the computation of flow peak attenuation, and to perform mapping for the estimation of flood zone depth and the flooded area of reach.The present study focus on various past research works carried out for flood plain and flood inundation mapping. The present study also focus on various hydraulic modelling software and usefulness of Geographic Information System as a tool on the field of water resources engineering and management.
