The paper depicts the various natural disasters occurring in different parts of the globe. With the help of information technology along with other branches of science it has become possible to study the basic environmental conditions before and after the events; even it becomes possible to predict the manifestations and indications before a disastrous occurrence. After the brief study of the different predictive models, it is easier to view the scenario of a country like India, where the major cities frequently faces the problem of urban flood which occurs due to continuous downpour. Along with the rain water the debris, sand particles and plastic solid waste (PSW) flowing from the nearby hilly or high level areas cause blockage to the major sewer drainage basins; resulting in different types of epidemic diseases. Urban flood can be avoided by keeping the flow of drainage basin clean, running and free of blockages. The study further helps to improvise a mathematical calculation of urban flood where the Lyapunov’s stability criterion is discussed and a relation between the parameters of the artificial flood is implemented using the theory.
