Assam Flood 2022: IIT Guwahati team to conduct survey of affected areas

NEW DELHI: The Indian Institute of Technology, Guwahati will help the Assam government in surveying the flood-affected areas by using drones developed by its startup to aid the relief and rescue work. According to officials, the state government has reached out to the institute to seek its expertise in surveying the flood-affected areas using drones to assess the condition in the villages where road connectivity has been disrupted due to the heavy flow of water.

The flood situation in Assam remained extremely critical on Sunday with many new localities coming under the impact of the deluge in several districts of the state and overnight incessant rain inundating more areas in Guwahati. Torrential rains for the past week have thrown normal life out of gear in parts of Assam. Landslides have also been reported from another half a dozen places in the city, including Kamakhya, Kharghuli, Hengerabari, Silpukhuri and Chandmari Colony. Knee-deep water and partially submerged vehicles on submerged roads were seen at many major intersections in the capital city.

In some places, water levels even crossed the waist. The approach road of the Guwahati railway station was also inundated. "The government has approached us and we will be beginning the work as soon as possible. We will be using the drones to survey the affected areas. Also, this exercise is important to help the government develop an action plan to prepare better ahead of the monsoon season considering the area is prone to floods and landslides due to its geographic location," Parmeshwar Iyer, Dean, IIT Guwahati told PTI. "The drones will be used to conduct aerial surveys of the areas which have been severely affected and some villages where road connectivity is disrupted due to heavy water flow. The exercise will be helpful in identifying areas where people could be stranded, immediate evacuation is needed and relief material needs to be provided," he added.

Drones developed by IIT Guwahati at its startup venture, Drones Tech Lab, have previously been used for faster data collection in several projects on the land survey, river mapping, agriculture, healthcare and disaster management. "One major challenge in surveying flood-affected areas with drones is the wind accompanying rivers during floods, hence the drones which are equipped to withstand the wind speed are needed. These drones have been used in disaster management during incessant flooding in Majuli island of Assam and for dengue prevention in Kolkata," said Debajati Deka, co-founder of Drones Tech Lab. "Before this, we have catered to different markets encompassing several Indian states which include Karnataka, Jharkhand, West Bengal, Assam and Meghalaya to name a few. The survey and mapping conducted finds applications in various domains which range from mining activities, wherein using drones the exact volume of mine can be assessed with absolute accuracy," he added.
