摘要：
The causes for coastal erosion around Pondicherry and Ennore were analysed. Wave refraction patterns exhibit convergence of wave energy around Ennore leading to erosion. The presence of artificial structures of Chennai port jetties has had its influence on the erosion around Ennore. But the coastal erosion around Pondicherry is neither man-induced, nor wave-powered, but may be ascribed to cymatogenic downwarping, which is a neotectonic activity. River migration pattern around Pondicherry suggests that the area has been subjected to downwarping in the Quaternary.
