Palk Bay

Palk Bay is a semi-enclosed shallow water body with a water depth maximum of 13m.[1] It is located between the southeast coast of India and Sri Lanka. Palk Bay is located between 8° 50′ and 10° North latitudes and 78° 50′ and 80° 30′ East longitudes.[1] The width of Palk Bay ranges from 57 to 107 km and the length is around 150 km.[1] Palk Bay is considered to be one amongst the major sinks for sediments along with Gulf of Mannar [2]. Sediments discharged by rivers and transported by the surf currents as littoral drift settle in this sink.[3] Few scientists[4] have tried to understand the wave characteristics within the Palk Bay. In the southern regions close to Dhanushkodi, wind seas dominate. The northern Eastern region of Palk Bay is exposed to the Bay of Bengal through shallow Palk Strait and hence the swells can enter the PB through this opening. To the south of Palk Bay, Adam's Bridge separates Palk Bay from Gulf of Mannar. Despite being a very shallow channel, Wave effects are transmitted to a small extent through the Adam's Bridge passage.[1]
