Mouth of Rianila

The Rianila reaches the Indian Ocean on Madagascar's eastern coast near Andevoranto. Its waters drain a route from the island's interior through forested country to the coastal plain. Andevoranto stood close to the river mouth and was known by the late eighteenth century as an important centre of the Betanimena. Canoes carried produce along the river and coastal waterways, bringing the interior into contact with the shore.
