Abstract
The present paper deals with the monitoring of the seasonal variations of physico-chemical characteristics of Neyyar, in Thiruvananthapuram district. The study was conducted in the surface water collected from ten stations of the river basin during the period October 2006 - September 2007. From the results of the study it was found that almost all the physico-chemical attributes analysed exhibit spatial and seasonal variations. Also various anthropogenic activities in this area enhance the sodium concentration in the down stream portion of the river.
