Sin: කොලොන්නාව kolonnāva – Tam: கொலன்னாவ kolaṉṉāva

‘Kelani Plain’  WP,  Sri Lanka

Kolonnawa is a suburb of Colombo and, like its parent city, its name probably derives from the Kelani Ganga: kolon is a corruption of kelani.

Kolonnawa is part of the flood plain of Kelani river: 70% of the land is below sea level and is dependent on bunds for flood protection – which is not always effective!
