Many who visited #Rameswaram would have noticed northern coastal parts of Island(Palk bay named after Robert Palk) do not have waves but southern parts(Gulf of Mannar) has waves. Why.?, It is all geography.
It is one of the unique geographical feature in #TamilNadu #India 1/n

Palk Bay is a closed shallow sea(like a costal Lagoon) with ~15000sqkm area. In the east, it has - #SriLanka, west - #TamilNadu, North west - Cauvery delta, North east - Bay of Bengal (Palk strait-sea opening), South - Rameswaram island, Adam's bridge sand bar & sea openings 2/n 
1. In Palk Bay, bay of Bengal water enters through Palk strait and connected to Gulf of manner in the south through two openings.
2. Wind/Swell wave (sea waves due to wind flow over surface of sea in fetch distance) found it difficult to enter Palk bay though Palk strait 3/n

3.North Palk bay has some swell/wind waves but in the south near Rameswaram, it is only sea wave (small wave due to local wind condition)
4.Gulf of Mannar(South of Rameswaram) is much more open, Gulf wind wave, flow northward, even cross through Adams bridge & enter Palk Bay 4/n

5. This effects could also be explained using wave diffraction,standing wave & wave through one end closed large open channel
6. lot need to be studied depends on the wind flow, weather condition.etc
7. River sediments from Palk bay deposited near Rameswaram creating sandbars 5/n

8. Palk Bay is also an unique eco system. North Palk Bay marine environment is different from south bay
9. Currents from Bay of Bengal & Gulf of Mannar transport river sediments into Palk Bay creating shallow sea with sand bars
10.Palk Bay is one of 5 Sediment sinks in #India 6/n

11. River water inflow into Palk bay also important in sediment and keep the salinity in check. Map shows the river drain in Palk bay 7/n
12.Shallow sea allows more sun light to penetrate into sea surface. Giving unique color to sea. Sunlight with sediment makes it ideal for see grass & coral reeves. Creating unique under water ecosystem full of life. 8/n
13. The bay is a highly productive ecosystem. it has 302 species of marine algae, 580 species of fishes, five marine turtle species and 11 seagrass species and several species of mangroves. It need to be protected with sustainable measure 9/n
14. The bay is also among one of the biggest fishing spots in south India
15.Control of Katchadeevu also decides area of control.
16.Bad fishing practice without sufficient investment in modern equipment is killing ecosystem
17.Trawling fishing practice is killing Palk 10/n

@srkias2012 Sir, this is about Palk Bay. Thoothukudi dt, which share beautiful and important Gulf of Mannar Island chains. Palk Bay also has its own unique aspects as a Sediment sink and shallow ecology.
@rajbhagatt Hello-ji, when you are free, I request you too look into sediment sink behavior of Palk Bay, which river sediments settles here creating waveless shallow lagoon kind of sea here..?. Will be geart, if you could provide ur insight. Pudukottai dt has no wave filled beach
@prvivek @tamilashokkumar this thread explains about why there is no waves
