The Buckingham Canal was constructed mainly for which purpose?
- A.Irrigation of the Krishna delta
- B.Navigation along the Coromandel coast
- C.Flood control in the Godavari basin
- D.Supply of drinking water to Hyderabad
Correct answer
Explanation
The correct answer is B, navigation along the Coromandel coast. The Buckingham Canal is a salt water navigation canal dug in the nineteenth century along the eastern coast, linking the lagoons and backwaters between Vijayawada in Andhra Pradesh and Chennai in Tamil Nadu, and it was used to carry goods and to relieve famine by moving grain. Option A is wrong because the Krishna delta is irrigated by canals from the Prakasam barrage at Vijayawada and not by the Buckingham Canal. Option C is wrong because flood control in the Godavari basin is handled by barrages and embankments on that river. Option D is wrong because the canal does not reach Hyderabad, which lies far inland on the Deccan plateau. This is the standard exception question on Indian canals: almost every other major canal is for irrigation, this one is for navigation.
