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.
