Which is a tidal port?

Appeared in: HPSSC Staff Nurse - 2021

Explanation

Kandla Port, located in the Gulf of Kutch in Gujarat, is a classic example of a tidal port.
A tidal port is characterized by shallow water depths where navigation is highly dependent on the rise and fall of the tide.
Ships entering or leaving Kandla must often wait for high tide to ensure they have enough water under the keel to navigate the approach channels safely.
This port was developed after the partition of India to compensate for the loss of Karachi port to Pakistan.

Option A: Mumbai Port is a natural deep-water harbour, meaning it has sufficient depth for large vessels to navigate at any time, irrespective of the tide.
Option B: Marmogao (Mormugao) Port in Goa is also a natural harbour, not a tidal port. It is one of India's leading iron ore exporting ports.
Option C: Paradip Port is an artificial, deep-water port on the east coast of India. It was man-made and is not dependent on tides for navigation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types of sea ports in India as background academic context rather than a clinical decision trigger.
Understanding the different types of ports is crucial for national and international trade, logistics, and supply chain management.
Tidal ports require precise scheduling and navigation, impacting the turnaround time for ships and overall port efficiency.
The development of different port types is based on the geography of the coastline and the economic needs of the hinterland they serve.

How to Approach the Question

First, understand the question. It asks to identify a 'tidal port' from the given options.
Define 'tidal port' in your mind: a port where water level is affected by tides, and ship movement depends on high tide.
Recall or deduce the characteristics of each port listed in the options.
Evaluate Mumbai: Known as a major, busy port. It's a natural deep-water harbour, so it's unlikely to be tidal.
Evaluate Marmogao: A major port in Goa, also a natural harbour.
Evaluate Paradip: A major port on the east coast, known to be an artificial, deep-water port.
