ABSTRACT
Floods being unforeseen overflow of water submerges the dry land and are the most quotidian and widespread natural disaster. Heavy rainfall engendering to overflowing rivers begets large volume of waters in the cities. Being the most common natural disasters, they have affected many Indian states. Timeline of such grievous flood events each year, highlight the susceptibility of urban areas to the ubiquitous effect of climate change and ascertain the demand of evolving resilient flood risk management strategies. Flourishing Green Infrastructure in cities acts as such a strategy assisting water retention, accelerating the drainage into watercourses chiefly at the time of floods. Implementing Green Infrastructure as a means of flood risk management methodology allows to extract the diversified potential of the site along with many other ecosystem services. To appreciate the implications of using Green Infrastructure as a flood risk management approach the author develops a system dynamics model presented in the form of Casual Loop Diagram in the paper. System Dynamics is a modelling method that is used to forecast multiple scenarios in a city based on real world problems and thus consequently supports decision making using integrated forecast and scenario simulations based on the datasets to yield results.
