Flood is a phenomenon by which the living and non-living entities that belong to the environment suffers various losses. Human beings cannot totally avoid floods but the only thing humans can do is, they can develop suitable systems to predict & subsequent measures to alert the people about its occurrence. There are many technologies available to predict and prevent. There are many natural disasters that lead to floods. Some of them are heavy rains and tropical cyclones. These floods cause materialistic and human damage. The main reason behind development of flood alert system is the intimation of flood well in advance so that human losses can be controlled by evacuation of people to safe places and also protects valuable properties. Despite certain damage occurs due to the drawbacks of the system. This paper explores flood warning systems and issues associated with each of them.
