Excellent data. Lot of us have been saying that Tibet is on the leeward side of Himalayas. It is thinly populated for a reason (not enough water). While China does have some control over the water which will definitely hurt us and Bangladesh, majority of the catchment area is in our territory.
Regarding using this data with the other side. I'd rather not. I love it when they keep bleating on wrong assumptions.
No completely correct.
Majority of catchment area of Brahmaputra by area is in Tibet, but it is such a barren cold desert with rainfall of average 200mm that water runoff from Tibet is negligible comapared to 2900mm average rainfall of NE, even if catchment area of Brahmaputra in India is less than that in China.
Also, there are only three small streams as tributary of Brahmaputra in China; while In India there are 15+ major rivers and countless streams draining into Brahmaputra.
