Sri Lanka Island country in South Asia

Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia, located in the Indian Ocean to the southwest of the Bay of Bengal and to the southeast of the Arabian Sea. The island is geographically separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. The legislative capital, Sri Jayawardenepura Kotte, is a suburb of the commercial capital and largest city, Colombo.

Starting from the hills in Puswelihena in Horana Division of Kalutara District, it flows northwards through a low-lying flat land (6–10 meters above sea level) converted into rice fields, which ultimately becomes the stream's flood plain during rainy seasons. On its way, the stream is joined by the Ma Dola starting from the hills of Madoluwawa and Kurugala, the Angomuwa Oya starting from Angomuwa and Miriyagal Kanda and the Arukwathu Oya starting from Udagama Kanda (1492 feet above sea level). The stream flows for 16 km down its valley before joining the Kelani Ganga near Hanwella. The lowest part of its valley is mostly covered by a large marshland known as Barawa marshland, where there are river loops and islets on its course. The flood plain of the stream is flooded many times annually mainly during the monsoon season from May to September and the inter-monsoon season of October and November.
