Abstract

                                In the river Pennaiyar. its tributaries and irrigation canal 27 places weto, selected and water samples were collected at monthly intervals and analysed. The results showed that the water in all the places had medium salinity hazard (EC of 0.25 to 0.75 mmhos/cm) whereas the stream at Periyapallam had high salinity hazard. The sodium adsorption ratio was in the range of 2.28 to 6.61 (low sodium hazard). The RSC was within the marginal limit in 76 per cent of locations. The quality of water along the river course and in the right main canal had not varied appreciably. But higher EC, pH, SAR, RSC and SSP values were observed in LMC after leaving the Mohamed Ghouse tank. Thus Mohamed Ghouse tank served as a source of salt for the water flowing in left main canal.
