Consider the following statements about a river: This river originates in the Hindu Kush mountain range and flows into Hamoun wetlands after covering a long stretch of about 1,100 km. There has been serious conflicts between two neighbouring nations regarding the sharing of water from this river. Identify the river from the following:
- A.Mekong
- B.Tarim
- C.Indus
- D.Helmand
Correct answer
Explanation
The correct answer is D, Helmand. The Helmand rises in the Hindu Kush west of Kabul, crosses southern Afghanistan and ends in the Hamoun wetlands on the Afghanistan-Iran border.
The Helmand is the longest river of Afghanistan, running about 1,100 to 1,150 km. It is an inland river: it does not reach the sea but drains into the Hamoun lakes and marshes of the Sistan basin, shared by Afghanistan and Iran. Iran depends on this flow for the Sistan region, and dams in Afghanistan such as the Kajaki dam have led to long disputes. The two countries signed the Helmand River Water Treaty in 1973, but quarrels over its share continue.
A is wrong because the Mekong rises on the Tibetan Plateau and flows to the South China Sea through South-east Asia. B is wrong because the Tarim flows through Xinjiang in China and ends in the Taklamakan region. C is wrong because the Indus rises in Tibet and flows into the Arabian Sea, not the Hamoun wetlands.
Exam tip: Helmand: Hindu Kush to Hamoun wetlands, Afghanistan-Iran water dispute, treaty of 1973.
