Q1. The Indus delta shrank after which barrage cut off most Indus flow to the sea and changed coastal agriculture and fisheries?
Answer: Kotri Barrage
Explanation: Kotri Barrage (also called Ghulam Muhammad Barrage), built in 1955 near Hyderabad, is the last major barrage on the Indus before the sea; it diverts most remaining river flow into irrigation canals, drastically reducing freshwater reaching the delta.
