Floods are natural risk with a very high frequency, which causes to environmental, social, economic and human losses. The floods in the town happen mainly due to human made activities about the blockage of natural drainage, haphazard construction of roads, building, and high rainfall intensity. Detailed maps showing flood vulnerability areas are helpful in management of flood hazards. Therefore, present research focused on identifying flood vulnerability zones in the Pune City using multi-criteria decision-making approach in Geographical Information System (GIS) and inputs from remotely sensed imageries. Other input data considered for preparing base maps are census details, City maps, and fieldworks. The Pune City classified into four flood vulnerability classes essential for flood risk management. About 5 per cent area shows high vulnerability for floods in localities namely Wakdewadi, some part of the Shivajinagar, Sangamwadi, Aundh, and Baner with high risk.

Multi-criteria analysis is effective geospatial techniques for identifying the flood vulnerability zones and disaster risk reduction in Pune city.

Six major criterion are considered for mapping of flood vulnerability: land use/ land cover, distance from channel, drainage density, rainfall, elevation, and slope.

The weights for criterion are assigned based on expert’s opinion and previous case studies.

The flood vulnerability is classified into four classes: very low, low, moderate and high flood risk.

About 5% of study areas shows higher vulnerability for floods in Pune City.
