As the southern part of the Indian Peninsula including the state of Tamil Nadu (TN) (Figure 1 a and b) is a low easterly gradient plain, the rivers that originate from the Western Ghats and the uplands in the west seem to have flowed towards the east with stable dynamics as evidenced from their well-evolved life histories with youthful, mature and old stages. So, the mouths of these river systems provided favourable avenues for ports and the related flourishing maritime activities since historical times. The port city of Poompuhar located at the mouth of River Cauvery in TN was one such a city of glory and had a prominent maritime history attracting traders from several countries (Figure 1).
