Urban flooding is a result of both overflowing rivers and the ignorant ways in which our cities are adapting to urbanization. Talk about it. Mention the National Disaster Management Authority’s rules for urban flooding in this context.
As cities expand, more people move into them, a phenomenon known as urbanization. Due to the increase in population in cities, there will be an impact on the environment.

As cities expand, more people move into them, a phenomenon known as urbanization. Due to the increase in population in cities, there will be an impact on the environment. To solve this there is a need for urban green spaces like parks, gardens, etc. These can increase the quality of air and reduce the rising temperature in the cities. It also helps to improve the health of humans by reducing physical and mental health-related issues, and wellbeing and also balances the ecosystem. This also increases the economic benefits for the nation by increasing the employment opportunities for managing green spaces and also a better value for commercial and residential properties.
This enables the increase in number of sustainable cities in India. This helps the nation to increase resilient processes and also sustainable practices to increase sustainability and make India a sustainable nation.

The case of urban flooding is gradually becoming a major concern in cities, not only due to floodwater from over flowing rivers but also due to sudden and haphazard urbanization that ignores the possibility of a natural drainage system and the equanimity in that ecological system. Many urban areas are undergoing intense flooding because of:
1. Natural Drainage System Degradation: When people move to urban centers they stretch their dwelling places towards rivers, lakes, wetlands and other forms of natural what one may term as drainage channels. But while absorption by soil, construction, roads, and other surfaces with no permeable surface takes over, they lead to more runoff.
2. Insufficient Drainage Infrastructure: Every town has established their drainage systems aiming at a different population and receiving less rainfall, meaning they cannot transport the current volumes of water and even more so with the addition of depth from climate change.
3. Uncontrolled Building: Floodplain structures, bad land management, and ill-designed structures hinder water flow, thereby, increasing the impact of rainfall.
4. Problems with Waste Management: Disposal of wastes in the wrong manner leads to blocking common utilities like drains hence minimizing capabilities of efficient storm water systems leading to floods which are much worse.
From the National Disaster Management Authority guidelines for urban flooding
India’s National Disaster Management Authority has also evolved various handiness to assist the cities to better realize and control urban flooding. Some of the major guidelines developed by the body include the following:
1. Urban Flood Zoning and Mapping: NDMA recommends that cities assess flood prone areas to determine the degree of risk and regulate those areas accordingly. It can therefore be prescribed in those regions in order to check reckless development while urban development can be directed towards reduction of effects of flooding.
