Abstract
El-Nino refers to the cycle of warm and cold temperature of ocean currents,which is accompanied by high air pressure in the Western Pacific and low air pressure in the Eastern Pacific.Floods due to the El-Nino effects are widespread and seems to be inevitable in the 21st century. Such negative impacts increase day by day. Every year there are loss of habitats and destruction of human establishments mainly due to the unadvised actions of man. The aim of this project is to provide a Flood Mitigation System (FMS) which can be implemented to any class of the society. It can be used to protect individual establishments like schools,hospitals and malls or colony of houses. The main principle is to effectively distribute the flood water via channels that are closed during normal conditions. The area that has been studied to better understand the effects of floods is the Chembarambakkam Lake.During the South Indian Floods 2015,this lake was one of the greatest victims. The area affected by the overflowing of the lakes include the places that come under the town and the village panchayat. This method of mitigation protects the man-made property during floods and also reduces the risk of flooding. When the water is effectively distributed, the possibility of stagnant water is also eliminated which reduces the chance of flooding.
