Climate change and urbanisation are causing a significant rise in the frequency of urban flooding, water-logging, and other related hazards. This study evaluates the existing drainage systems in terms of their effectiveness and efficiency, as well as their usefulness in mitigating flood hazards in cities. The drainage network within the Delhi Cantonment area is considered to evaluate the use of drainage systems to mitigate the effects of climate change.
The impact of climate change is just one of the various trials that Delhi is facing. In particular, the expected increase in heavy rainfall, could render the current drainage systems of Delhi effectively defunct, leading to flooding, as well as potential loss of life and property.
The study looks at the challenges faced by the existing drainage system in the Delhi cantonment area, and offers actionable solutions for the same. It also offers policy changes that can be implemented for better management of the drainage network across the NCT of Delhi.
