Firstly India expects China to manipulate the Bramhaputra flow with or without Pakistani requests.
China will do what is best for China, India has to look out for itself. That is why india is building a massive counter dam on Bhramaputra, to regulate the flow water in India atleast. There after what Bangladesh does is their own headache.

Secondly, India has moved up from building dams on Indus rivers is now building canals to interlink the western rivers, with Eastern rivers.
Eastern rivers are already further linked to canals which go all the way to Rajasthan and beyond.
How does one bomb cannal that is something you will have to figure out. Conventional logic suggests, bombing a canal only makes it deeper.
Thirdly let's for argument sake you do bomb some dams in India, you will get twice as much flooding in Pakistan, initially from Indian dams bursting open and Secondly when India bombs Pakistani dams in response.
Fourthly during world War 2. British spent years developing bouncing bombs to breach German dams in Ruhr industrial region.
In 1943 British conducted a night time raid on 3 German dams..causing massive damage to the dams and killing 1600 civilians who lived downstream of the rivers.

Blowing up of the dams also cut the electricity to the whole industrial Ruhr region. However Germans were able to restore electricity to the region with in 3 days of the bombing and were able to completely repair all the dams put them in normal use within 4 months of the bombing.
So yes we are ready to risk it!
