Question

Which of the following ports is confronted with the problem of silt accumulation?

• A. Mumbai port
• B. New Mangalore port
• C. Kolkata port
• D. Paradwip port

Answer 1

The Correct Option is C

The problem of silt accumulation is a significant issue for some ports due to their geographical location and river systems that deposit sediments. Among the given options: 

• Mumbai port - Located on the west coast of India, it doesn't face significant silt accumulation issues due to its coastal location and deep natural harbour.
• New Mangalore port - Also on the west coast, it primarily handles cargo like crude oil and doesn't experience major silt accumulation.
• Kolkata port - Located on the east coast near the mouth of the Hooghly River, it is notorious for silt accumulation. This riverine port is significantly affected by sediments carried by the Ganges-Brahmaputra river system.
• Paradwip port - On the east coast, primarily handles cargo like iron ore and doesn't have the major siltation issues faced by river ports like Kolkata.

The correct answer is: Kolkata port, due to its positioning along a river with heavy sediment flow.

Answer 2

Kolkata Port (formerly known as Calcutta Port) faces the issue of silt accumulation. The port is located on the Hooghly River, which has a tendency to deposit silt, reducing the navigability of the river and making it difficult for larger ships to access the port. This issue has been a long-standing problem for Kolkata Port, and extensive dredging operations are required to maintain its depth and ensure smooth operations.

• Mumbai Port (A): Mumbai Port does not face significant issues with silt accumulation as it is located in a deep, natural harbor.
• New Mangalore Port (B): While New Mangalore is located in a coastal area, it does not face the same level of silt accumulation as Kolkata Port.
• Paradwip Port (D): Paradwip Port, located in Odisha, does not have the same challenges with silt accumulation as Kolkata Port.

Thus, the correct answer is Kolkata port.
