Paper Title
Enhancing Resilience: Strategies for Flood Mitigation in Mumbai’s Urban Expansion through Storm Detention
Abstract
With Mumbai City’s burgeoning population and plans for expansion eastward, the inception of a sister city,
Naina, is on the horizon. However, Mumbai’s historical struggle with flood-related issues poses a critical challenge to this
development. As the footprint of the city extends, the impervious cover in the targeted area is set to increase, exacerbating
stormwater management concerns. This paper investigates the potential surge in storm flow resulting from heightened
impervious cover using the rational method. Moreover, it aims to underscore the risk of inundation if adequate mitigation
measures are not employed or if the existing stormwater infrastructure proves inadequate. The study proposes the
implementation of underground detention ponds as a strategy to alleviate excess storm flow, utilizing rational method
calculations to inform their design. By striking a balance between expanded impervious cover and effective detention
systems, this research seeks to offer a comprehensive approach to mitigate flood risks in the development of Naina and
ensure sustainable urban growth.
