Abinaya Assistant Professor, Department of Civil Engineering, Saveetha Engineering College, Chennai, Tamilandu, India ABSTRACT India has totally 4050 large dams and 475 are under construction as per the National Register of Large dams 2002. Some of these dams were built in the early 19th century and many during 20thcentury.Every dam need a flood inundation map during the heavy rainfall or dam break for dam operation so the main objective of this paper the flood inundation map was prepared for Sathanur Dam for the maximum discharge of 8000 cumces which was occurred in the year 1973 using HEC-RAS software. The totally capacity of the reservoir is 300.601Mm 3 . Key words: Sathanur dam, HEC-RAS, flood inundation map. Cite this Article: V. Aishwaryalakshmi, Nilesh Kumar, M.G. Prathap, B.

INTRODUCTION Dams store large amount of water uncontrolled release of heavy water has great potential for loss of life and damage to properties. Therefore it is important to save the people and properties in the downstream. It was observed that the major floods occurred in year 1942,1964,1966,1972,1992. Out of this 1972 has the maximum discharge of 8000 cumces for this maximum discharge condition flood inundation map was prepared. This studies includes
