The boy's football team trapped in Tham Luang Cave have officially been rescued. The bravery of the people involved can't be discounted, but <keyword id="6355118" type="UNKNOWN" weightage="20" keywordseo="technology">technology</keyword> had a large part to play as well. In <keyword id="3658" type="COUNTRY" weightage="20" keywordseo="India">India</keyword>, flooding is just as big an issue. Mumbai gets water logged every season, people on pilgrimages get trapped and residences on River banks are destroyed periodically as water levels rise due to monsoon or flash floods. Urban flooding, specifically, is a not-so-new a phenomenon that's been wreaked havoc all over the country. In either case, technology can be used for all the right reasons to get the job done. Tech lessons for India 1. Don't wait for the submarine <a href="http://www.businessinsider.com/thai-rescue-officials-to-elon-musk-submarine-idea-is-not-practical-2018-7">Elon Musk</a> wanted to help and had the technology in place do so as well, it's just that it was a little late and the human rescue operation was already underway. Not to mention that the Navy SEALS had already advised against using<a href="http://www.wired.co.uk/article/thai-cave-rescue-boys-news-tech"> 'un-tested'</a> technology when the PTT Exploring and Production Public Company Limited (PTTEP) offered their underground vehicles. Equipped with sonar scanners that could help create an underwater map of the cave and help divers navigate through the muddy water, it was still recommended that they don't enter since the terrain was very different from what the vehicles were used to and had been tested in. India, as of now, doesn't have an underwater technology to help with <keyword id="6369083" type="UNKNOWN" weightage="20" keywordseo="flood">flood</keyword> operations. Not that it needs to match <keyword id="6355315" type="PERSON" weightage="20" keywordseo="elon-musk">Elon Musk</keyword>’s levels, but it would be immensely helpful in any situation people are stuck underground. Also, don't wait for the submarine. Rescue operations are time sensitive and critical, if you have resources on hand, use them. 2. Map it out Anyone who's played PUBG or Call of Duty knows that you can see the terrain so much better from a height. It's actually just basic battle strategy. Which is why it made so much sense for the PTTEP, in coordination with<a href="https://www.denverpost.com/2018/07/11/denver-3d-earth-mapping-tech-thai-soccer-rescue/"> InterMap</a>, to create a 3D aerial map of the cave and terrain where the children and their coach were trapped. Ordinarily, PTTEP uses these drones, which<a href="https://www.inverse.com/article/46898-thai-cave-rescue-3-engineering"> inspect</a> high-risk potential drilling sites, but combined with mapping technology they were able to ascertain potential entry points. Drones are key. They do away with the human effort of the ground team to manually climb and check each location. This is important because it goes a long way in simplifying the operation. <keyword id="6354474" type="UNKNOWN" weightage="20" keywordseo="drone">Drone</keyword> usage in India, even by government authorities, is hardly prevalent. At most it's being used for<a href="http://www.dnaindia.com/mumbai/report-govt-plans-to-use-drones-for-spatial-survey-across-maharashtra-2635229"> spatial surveys</a> and<a href="https://factordaily.com/drones-for-precision-agriculture-in-india/"> precision agriculture</a>. Urban flooding, a paradigm that India is still grappling with, could find real relief in such a measure. In the past, underwater expressways and submerged low-rise buildings have proven<a href="https://economictimes.indiatimes.com/opinion/interviews/chennai-floods-was-the-largest-rescue-operation-ever-by-ndrf-op-singh-dg/articleshow/50390863.cms"> hard to spot</a> in muddy waters. 3. Pump-di-bump Too much of good thing can prove to be bad. An abundant water supply is a boon for agriculture, and on the other hand floods have the potential to wreck in, an otherwise, fruitful season. During the cave rescue, it was India's very own <keyword id="123991" type="DOMAIN" weightage="20" keywordseo="Kirloskar-Brothers">Kirloskar Brothers</keyword>' Limited (KBL) who provided the<a href="https://economictimes.indiatimes.com/news/politics-and-nation/how-an-indian-firm-helped-thailand-rescue-12-boys-trapped-in-a-flooded-cave/finally-hooyah/slideshow/64944153.cms"> know-how</a> to go with the dewatering pumps. On the recommendation of the Indian Embassy in <keyword id="3739" type="COUNTRY" weightage="20" keywordseo="Thailand">Thailand</keyword>, the company even had four high capacity specialised Autoprime pumps in place to be picked up from Maharashtra if the need arose. This measure, and others which are similar, are already being implemented in few areas in India. For example, Grundfos India<a href="https://timesofindia.indiatimes.com/city/chennai/Grundfos-mobile-pumping-station-used-in-Chennai-to-pump-out-flood-water/articleshow/50140951.cms"> provides</a> the Chennai City Corporation with mobile pumping stations that are specifically designed for floods. Even Mumbai<a href="http://www.freepressjournal.in/mumbai/mumbai-rains-crores-spent-on-procurrement-of-pumps-flowed-into-the-floods/1128756"> spends</a> crores on pumps to dewater the city. 4. Calling Houston The devices that were originally used to contact the missing football team weren't new-age, but actually 20-years old. Issued by Derbyshire Cave Rescue Organisation, these HeyPhones can<a href="https://hub.packtpub.com/the-tech-supporting-the-thai-cave-rescue-mission/"> operate</a> on such a low frequency that those waves can pass through thick rock walls. More than that, the Thai rescue team also got in touch with Maxtech Networks, an Israeli communication company. These guys provided 19 special handheld devices that could<a href="https://www.jewishnews.net.au/israeli-tech-aids-thai-cave-rescue/79552"> boost</a> the power of the default radio by 20 times. The system works on a 'daisy chain' mechanism that hops voice, video and data from one device to the next. One of the main obstacles that have to be overcome in emergency disasters is communication. Regardless of whether it is <keyword id="44522" type="LOCATION" weightage="20" keywordseo="Uttarakhand">Uttarakhand</keyword> or <keyword id="6358126" type="LOCATION" weightage="20" keywordseo="Himachal-Pradesh">Himachal Pradesh</keyword>, the gigantic spans of the mountains makes communication a hurdle. Even in 2014, the<a href="http://www.rediff.com/news/report/kashmir-flooded-with-woes-landslides-no-connectivity-communication-hit/20140909.htm"> Kashmir</a> valley was faced with no connectivity and isolation from the outside world when the floods hit. Floods are not a new phenomenon in India and the headline has, too often, been that poor preparedness is what caused of the disaster. Integrating some tech, making information more public and having some sort of integrated system in place are only the most basic of requirements.

Here's what India can learn from the Thailand cave rescue

In a tragic scene which unfolded following a massive landslide by a cloudburst in India's northern Himachal Pradesh state on Sunday, two buses carrying at least 55 passengers were swept off the road into a gorge. Sources indicate as many as 50 people have lost their lives in the mishap. Atleast 47 dead bodies were recovered on Sunday before search operations were called off. A confirmatory search is underway since today morning, but reports suggest all the bodies have been recovered. The incident happened in the Mandi district, 431 km (268 miles) north of New Delhi on early Sunday morning. Officials said the landslide struck around 12.24am on the highway near <keyword id="4884794" type="LOCATION" weightage="20" keywordseo="kotrupi">Kotrupi</keyword>, where the two buses had halted for refreshments. Sources said a Katra-bound bus was first hit by a big boulder, then the landslide. The bus rolled down 200 metres into a gorge. Its mangled remains were later retrieved by rescue teams. Teams of NDRF, Army, police and home guards were immediately deployed at the spot
