Abstract
Flood is a natural disaster and causes loss of life and property destruction. The objective of the study is to prepare a flood inundation map for a stretch of the river Cauvery for different return periods. To perform hydraulic modelling, the software HEC-RAS was used. GIS was used for spatial data processing and HEC-GeoRAS for interfacing between HEC-RAS and GIS. The obtained inundation map shows total submergence of areas nearby along the chosen stretch, highlighting the need for an adequate flood warning system and proper flood protection works along the stretch. These in conjunction with proper land use management and afforestation can significantly reduce the adverse effects of flooding, particularly in the low-lying areas. Results of such studies will help the departments and agencies concerned to formulate appropriate strategies for mitigating the flood hazard in the river basin.
