My brother who is working in chennai

[@adityasundar324]

I'm from Chennai, from one of the oldest neighborhood. My ancestors migrated to this city sometime in the 1800s and I have heard of how the city grew up to be what it is now. The reason why Chennai floods so much is because almost all of the lakes in Chennai have been filled up for real estate. There were huge lakes and tanks like Long Tank ( T. Nagar was reclaimed from that), Many parts of Nungambakkam was lake once. This is the same reason why even Mumbai floods every monsoon. We have filled up all the natural waterways. If one pulls up the map of Madras from early 1900s, one can see that none of the Old Madras areas gets flooded as badly as the 'reclaimed' parts.

[@shobith5509]

imd predicted that chennai will be fully submerged by 2100 but if you have any close relatives or your family friends from metrilogical department ask them how far is this true they say that yes its true but they say not by 2100 they decrease the life span even 50years more. like 2050 down the line but my prediction is 2041.

Sir thank you so much for uploading this video. I live in Chennai. I was very proud to born and living here. But the details u told made me stunned. Indeed what u said is right. Infact velacherry the name itself suggest it's a lake. But now it is a hub of IT sector. I wanted every people to share this video and help people to understand about the disaster which is approaching us(not very far)

[@Nutshellindia]

Thank you so much!

[@abby-kamakoti]

It's also ppl desire to built a house in a city on whatever the land they get.....they just rush to have a house in cities..

[@biswabhushanpatra9762]

Not the responsibility of people since they don't have much knowledge. What about the educated fools who are paid by the government for the sole purpose??

[@dhruvbhartia90]

Unplanned development is the chief reason for such a condition of Indian Cities.

[@bhatt24101982]

Why single out chennai,...Bangalore is at an elevation of 1000 m, we still hv floods here😁😂

[@neelkanth3002]

Atleast we still have lakes and natural slopes, the geography of bangalore is good for flood prevention

[@Sathish_12]

also Bangalore doesn't even receive half of what Chennai and Mumbai go through

[@chandershekar2445]

Aww, thanks so much😌

Such an informative video explained with facts and figures... Loved it i subscribed your channel keep making informative videos

[@Nutshellindia]

Yaay! :)

[@nirmaladeenathayalan1355]

This vid makes me realize that the people who are affected by flooding, rain water coming into their house, water clogging in areas completely deserve it. Since they wanted to occupy the land belonged to lakes, rivers, canals, drainage systems and convert them into houses. They must understand that not every single sq.ft in the city is residential. You go against nature this is what you get.

[@barathg3674]

Chennai is growing horizontal rather than vertical..

[@kalyanmoturu9325]

Content wise it is exceptionally good, but this video will be most viewed by people from southern part of india who were not well versed with hindi. So instead of a bi-lingual video make it in english. Which really helps

[@Strawberry_champagne203]

If you open your eyes you can see there are subtitles at the bottom

[@shubhampatil5494]

Pleasemake a video on Mumbai city too.

[@alagappachettiaralagappan6020]

Hi, This storm water drainage system built was not engineered properly, In fact before construction our area was not affected, During heavy rain, little amount of water stagnated and drained after few hours, Now after construction they have not provided proper gradient and proper size, If you analyse the size of the drain is uniform, normally in the starting place it should be small as it travels the size should increase, and in the end place it should be able to flow in a stream or wherever but due to blocking the water is not able to flow and reverses, must be studied and rectified

[@sakshighadge1669]

Why not government make a law that if any construction is going on any mangroove or on in social property it is them responsibility to do not block the water.and it should be like as before.

[@sindian7830]

People Going abroad should stop buying flats assuming as a asset and a living area while the plan to settle in india in their old age. These flats will be obsolete and old while they return back. This creates high demand and lot of boom in real estate, end up with lot of vacant property.

Surat used to flood every year in monsoon when I was kid, now it never floods!! Surat grew unlike any other city of India in last 20 years. Surat has 70% population born outside of Surat district and 30% population born outside of Gujarat, making Surat as highest migrant city in India. Even having such rapid growth, all odd against the city, Surat don’t flood anymore. City which was not even in top 20 big cities of India in 1970s (most dirty city of India), now it’s 7th biggest city of India (2nd cleanest city of India for last 10 years), having 7.5 million people. You gotta have efficient vision based Municipal corporation working towards goal. Surat is one of the cleanest city in India and lowest number of slums in entire India, due to high number of construction of slum relocation apartments. All slums I have seen during my childhood all are gone and relocated to apartment at place where slum used to exists. No blockage in storm water drains and city cleans their road almost every night! Very minimal garbage goes to drains. Any blame game doesn’t work until you have visionary person leading!

[@nirmaladeenathayalan1355]

Great stuff! I didn't hear about this total changeover abt Surat, only heard it was the cleanest city in India. I hope flooding in Chennai becomes non-existent in the near future 😄😁

[@shardamohite2670]

how come surat is highest migrant city in india, does it have more migrants than delhi , mumbai , bangalore ?

[@raviv3398]

@@shardamohite2670 Surat is industrial city, most migrant in Surat are from UP & Odisa, Maharashtra & Telugu land. Internal migrant are from Saurastra region of Gujarat. Most outside migrant in Surat are unskilled labours. 100% labour workers in textile is from UP or Odisha, my cousin’s factory has 800+ workers, most are from Odisha. As per 2011 census of India, Surat alone had double the people born outside of Gujarat than entire Tamilnadu state combined had people born outside of Tamilnadu. Even Surat municipal corp created gov schools in language of migrants, there are 55 Marathi, 7 Odia, 3 Telegu, some Hindi medium, Surat Municipal corporation run schools are there for migrant children. www.thebetterindia.com/164518/surat-migrants-schools-education-policy-news/amp/

Banglore having 96 lakh population, it had 17 lakh people born outside of Karnataka, Mumbai city, 30 lakh total population has 7.7 lakh born outside of Maharashtra, while Mumbai Suburban, 93 lakh total population has 26 lakh born outside of Maharastra. Surat has 28%, Mumbai total has 27% & Bangalore has 17%. Delhi is state, I don’t know how to compare here with city!!

[@raviv3398]

@@shardamohite2670 I guess I have given you enough evidence on your How Come question? India doesn’t rely on only IT industries clusters, there are many blue collar industry cities in India which gives more employment to big chunk of people from poor states, than any metro of India.

Chennai is a dirty city, a beautyful city turned dirty by human negligence... Policians play a major role, but no voice from people , people here are voiceless.
