"If the rule curve acknowledges 142 feet, here it is equal to permitted Full Reservoir Level (FRL) at the end of the season.

But if you blindly follow it, you will be forced to throw all the water downstream in case it rains."
So prudence is required when there is cyclonic circulation prevailing and heavy rainfall alerts are around.

One should never store upto FRL.

I had to fight to sell this important point on operational safery to many of peers too!
People are got confused with structural safety, hydrological safety and operational safety.

Your dam may be safe for 142 ft FRL, but if you plan to store water to the brim, you left with zero flexibility.

You are comprising the operational safety!
Also understand the philosophy & logic behind the rule curves.

They are not rigid lines, they are flexibile, an experienced reservoir manager should weigh the same with the prevailing weather.

When we take maximilist postures due to political compulsions, reason take backseat

Today's @the_hindu says concern on the #Mullaperiyar Dam was first raised in 1979.

As our research & memory is so short, let me share @timesofindia Mumbai Edition dated 11.05.1962 (a typed copy from Kerala Secretariat files) ImageImage
Interestingly, who raised alarm about safety of Mullaperiyar Dam after independence?

Not Kerala Engineers, it is TN PWD Engineers who said that the dam is seismically & hydrologically NOT SAFE and recommended strengthening!

They even published papers in reputed journals!
I have all documents with me to substantiate the above tweets, it is the consistent and continuous meticulous research I am doing since 2006.

Everything will be included, when I publish my book on #mullaiperiyardam.

I will write the book for the future generations

If someone is accusing High prices of Fuel is due to MMS Government's opening Petroleum sector to open market, they are shutting their eyes & propagating inconvenient truths.

A #thread on what lead to such a decision
Due to volatility of the markets, the very subsidies provided by the Government of keeping the fuel prices to check became unsustainable!

actual under-recovery in 2012-13 was ₹ 1,61,029 crore, out of which Diesel alone accounted for ₹ 92,061 crores (57%).
2012-13 Government provided cash compensation of ₹ 1 Lakh crore while upstream companies (ONGC/OIL/ GAIL) contributed ₹ 60,000 crore.

₹ 1029 crore was absorbed by the OMCs.

What ails India’s coronavirus genome sequencing system

The country sequenced only 0.2% samples till date, one of the lowest in the world

Evidence based policy? How dare you? downtoearth.org.in/news/governanc…
To date, Maharashtra (14,003 samples) and Kerala (5,485 samples) have sequenced and analysed 23 % and 9 % of the country’s total volume analysed. 

Do these % makes any sense? Be worried
Take the case of Kerala. 5485 samples out of a total identified cases of 40,90,036.

That means only 0.13% of the samples genome sequenced.

Do this is enough to conclude that what Kerala is witnessing now is only because of DELTA alone?

UK total population (6.82 crores ) is almost double of Kerala's (3.47 crores).

UK fully vaccinated around 60.38 % of its total population & partially vaccinated 9.46%.

Meanwhile Kerala fully vaccinated only 19.6% of its total population & partially vaccinated 33.5%. #Thread
Unlike UK, Kerala is not sovereign & cannot give indemnity bond or export vaccines.

Kerala is at at the mercy of the Union Govt to get its vaccines.

If supply is ensured, Kerala would have long back vaccinated its whole adult population, we have the wherewithal to do it.
Now comes to the qn of infections and deaths.

UK on 18th Aug had 497.3 infections/million while Kerala is having 617.5 infections/million

UK had recorded 1.64 deaths per million while Kerala recorded 5.16 deaths per million.

Of course, our infection & deaths are a concern.

But #Kerala's #COVID19 cases showing a downward trend, though it is not so significant ...

See the 7 day moving average daily infections graph.

How we will behave in coming days will define our #COVID19 trajectory.

Please be responsible to you and your society!
Not sure what we are now witnessing is the 3rd wave or 2nd wave, maybe it is like 2 monsoon overlap each other here.

If Kerala can fully vaccinate its population, then we can negotiate next wave.

Kerala has the wherewithal to fast vaccinate, if it is made available!
Thanks to our robust health infrastructure and health workers, which are spread in a uniform manner at the breadth and width of our State, we never seen a crisis like North Indian States witnessed.

Yes, around 10 days, our system stretched to the limit during 2nd wave peak.

India so far fully vaccinated only 9.7% & partially vaccinated 22.7% of its total population.

If we are taking our 94 crores 18 plus adult population, the above figures will be 13.3% and 33.1% respectively.

Statewise progress can be easily comprehended from this map. Image
The States who have fully vaccinated more than 20% of their population are given in GREEN.

While the worst performing States with less than 5% fully vaccinated are given in PINK
The highlighted cells in the table accompanying the map shows the States which are performing below national average as far as vaccination is concerned.

Unless India Govt makes Herculean efforts to vaccinate the population there, we are facing a great risk against 3rd wave.
