Catalogue of best practices for building flood resilience
This document showcases some of the measures which have been successfully implemented by Indian and global cities towards mitigating floods and building water resilience. The intent is to create a basket of solutions that Indian cities can choose based on their need and priority. Emphasis on replicability and scalability of interventions in the context of Indian cities has been considered while selecting the interventions. Additionally, the cost of implementation, scale of intervention and types of stakeholders involved in implementing flood measures are provided to help city officials plan for similar actions.
Urbanization related development like construction in low lying areas, natural drainage and flood plains along with inefficient storm water network are key for flooding and water logging. Further, with urban development, the area of impervious surfaces that deter ground water absorption are increasing, green cover that can absorb and divert flood water is decreasing and water bodies that have the potential to store flood water are disappearing. The outcome from such unplanned development patterns have resulted in severe flooding across many cities in the country. Moreover, water related management in cities like storm water management and maintenance of water bodies like rivers, lakes and canals are important.
