Ancient technology of jetties and anchoring points along the west coast of India

摘要

The Indian coast, with a long history of maritime activities, has been dotted with several ancient ports. The evidence for this exists in port-related structures on the shore and in relics lying in the sea adjacent. Marine archaeological explorations have revealed the existence of jetties at Dwarka, Rupen Bandar and Porbandar, and offshore anchoring points at Bet Dwarka, Miyani, Visawada and Somnath on the Gujarat coast. The preferred anchoring points fall in a water depth of 5-7 m. This communication also discusses the effect of tide when using jetties and loading points along various parts of the west coast India.
