Nashik gets ready for artificial rainfall

 According to district administration officials 1,000 million cubic feet (mcft) water has been reserved for Kumbh Mela.

Nashik is likely to get some artificial rainfall with cloud seeding to overcome the shortage of water during the Kumbh Mela and maintain a steady supply to the city thereafter.

According to district administration officials 1,000 million cubic feet (mcft) water has been reserved for Kumbh Mela. However, Nashik has received on 23 per cent of the annual rainfall this monsoon. The administration will have to release water into river Godavari from Gangapur dam during the days of parvani — the shahi snan (holy bath) — as well as for the month of the Kumbh parva.

The Gangapur dam as of now has about 2,146 mcft while its capacity is 5,630 mcft. If water from the dam is released for Kumbh Mela as per plans, it will leave the dam almost empty. Considering this shortage, the administration has been contemplating artificial rainfall and cloud seeding.

The International School of Professional Studies (ISPS), a private professional organisation, which has already been asked by the government to carry out the experiment and prove the technology, has on Thursday approached the resident district collector Jitendra Kaksute seeking permission to fire a rocket for cloud seeding in Nashik.

What’s cloud seeding?
Cloud seeding is done with a help of a rocket which is fired vertically into a cloud or bunch of clouds which is selected depending on its thickness and the distance from the land. The rocket is fuelled by sugar. Once the rocket is fired in the yellow spot of the cloud, it releases silver iodides which creates a reaction resulting into rainfall. The rocket takes about 5 seconds to reach the cloud and in next 40-60 minutes it is expected to rain.
The amount of rainfall depends on the cloud. The rockets are fitted with GPS system, cameras and recorders to record data which can be usefull to the MET department. —- Source DNA India
