India has faced more than 300 natural disasters in this millennium which has left the country in shackles and the people to fend for themselves in dire distress. Operation research comes into the picture and plays an important role in disaster management. Right from the positioning of supplies to the delivery, proper poetization and allocation of resources, OR is very important. The objective here is to be able to comprehend and outline the possible techniques that can be used in emergencies and at the same time try and check its feasibility in India. In order to facilitate the attainment of this objective, we went through several papers collected from published journals and used them to provide analysis and models. They helped us in coming to the conclusion that disasters like floods are not preventable and the use of operation research has made the job easier and at the same time leaving room for sufficient improvement in the field.
