A Study of Chennai - Water Scarcity Using Fuzzy Cognitive Mapping

S. Gayathridevi, T. Johnson and C. Vijayalakshmi

Chennai has been experiencing different kinds of rainfall and their monsoon patterns for the last seven years. In the year 2015, there was heavy rainfall in mid of November and on 1st December continuously for more than 40 hours. The huge downpour of rainfall took more than three days to drain a part and there was no rainfall for the rest of the yearly season. This type of abnormal rainfall does not help ground water recharge, instead it leads to disastrous measures. Though it was a heavy rainfall with approximately 500mm in a single day, it had simply drained to the Ocean Bay of Bengal with unprecedented damages to the Chennai city. Thus we could understand that rainfalls in a regular interval will help ground water recharging, otherwise it could merely cause catastrophes. So this kind of heavy rainfall and change in monsoon patterns for continues years ahead, are the hidden reasons for water scarcity especially at metropolitans like Chennai city; where population is in high density. This type of abnormal rainfall (or monsoon) causes flood like situation. This experience at Chennai made us to search, what type of measures to be taken in order to avoid this water scarcity in metro cities, we have considered some of the major factors related to the water scarcity and ground water related issues and applied using Fuzzy Cognitive Maps to find out the ideal solution
