Unique Ecosystem along Goan Rivers


Goan rivers are unique as they are both tidal as well as rain fed. During monsoons water from the mountains and watershed areas gets drained thru these rivers into the Arabian Sea. Major rivers such as Mandovi and Zuari cover a large part of Goa in their catchment areas and these are influenced by tidal flows and influx as much as 40 kms upstream.

This mix of tidal flows as well as rainfed system means that salinity levels vary differently then other rivers of India and this leads to an unique ecosystem of mangroves in the catchment a of the rivers.
