Between 25–28 September 2019, Pune, India, and its division received a heavy amount of rainfall which caused flash flooding. In addition to people lost to these floods, other rain-related incidents such as collapsed compound walls of buildings have killed at least 21 people.[2] Three NDRF teams along with the Army was deployed in the district for rescue operations.[3]

Background

The monsoon season in south Asia typically starts around early June each year and brings heavy rainfall and potential flooding to nation. However, the 2019 monsoon season started in late June and has been unusually heavy in terms of rainfall, with a 6.5% increase in rainfall averaged across India. In the Pune district, prior to the flooding, it had received 180% of its annual rainfall for the year due to the monsoon season, and its local Khadakwasla dam along with other three important dams were filled completely.[4]

Flooding

More than 16cm (06inches) of rain was measured in Pune, Baramati and Pune district between the night of 25 September and the afternoon of 26 September which was the highest rainfall in last 10 years. Coupled with the existing rain from the previous months, flash floods started to occur.[5] [6] The flash flooding was caused by short intense periods of rainfall that overwhelmed water runoff systems like nullahs and flooded roads.[7]

The full Khadakwasla dam saw an additional 8.7cm (03.4inches) of rain during this time, leading authorities to release some of the water to overflow into the Mutha River at a rate of 13891ft3/s to prevent damage.[8] Similarly, the Nazare Dam near Saswad was also at capacity, and its waters were released at a rate of 85000ft3/s into the Karha river late on night of 25 September, inundating areas of Purandar and Baramati.

Relief and rescue

Two teams of NDRF were employed in the Pune city and two teams were employed in the Baramati.[9] The flood caused 21 deaths, 5 missing and evacuation of more than 28,000 people living in the city.[10] [11]
