Urban cities have expanded to the forefront of economic activity due to the massive urbanization occurring worldwide. Due to rapid development and growth prospects in metropolitan cities, they draw many people from other places. Moreover, extreme events have become more frequent and intense due to global climate change. This congregation of urban development with climate change has led to an increase in the issue of urban flood. Hence, it is necessary to devise strategies based on natural elements to combat the worsening problem of flooding in urban areas. The term “Blue-green infrastructure” (BGI) refers to the fact that the “green” and “blue” can assist in addressing a variety of “water” related problems. Green infrastructure (GI) denotes techniques that use plant and soil systems with the ultimate goal of reducing flooding and sewer system overflow, while blue infrastructure (BI) refers to water elements like ponds, canals, etc. Using the case study of the flooding in Hyderabad in 2020 as an example, an attempt is made to understand the role of nature-based solutions (NBS) in urban flooding using geospatial methods. The flood monitoring model National Resources Conservation Services—Curve Number (NRCS-CN) is implemented on the GIS platform using spatiotemporal data for urban flood analysis. Further, the authors use alternative land cover, incorporating BI and GI which shows a 30% reduction in the flood depth compared to no BGI. Hence such NBS approaches are indeed effective in dealing with urban floods.
