Paleochannels of the Palar River West of Madras City: Possible Implications for Vertical Movement

Hydrogeological field observations indicatc that the river Palar, which now follows a south-easterly course in the vicinty of Kancheepuram, once flowed towards the north-east during quaternary times. The shift appears to have taken place in four stages. The shifts probably, suggest gently vertical movements to the north of the river. If such vertical movements have indeed occurred, It should be of interest to study their relation in regional vertical motions elsewhere along the east coast and their implications to regional hydrogeology of aquifers.
