Agitated over the State government's plan to allow sand quarrying again at the dry Nambiyar riverbed in the district, residents of various villages in Radhapuram taluk submitted a petition to Collector R. Selvaraj on Monday against the move.

Unlike the Tamirabarani, the Nambiar would very rarely experience flood even during active monsoon. Naturally, sand deposit on this riverbed is not so dense and deep.
