The Nallamada Drain flows were observed during September to December month . in the tune of 3 - TMC. During January to April and August months the outflow quantities were to the tune of to TMC. It was estimated that on an average about TMC of water flows through the drain annually. The Electrical Conductivity of drain water up to the end of March, 2009 was less than dS/m indicated that the water was fit for irrigation. The pH values of the drain water was estimated to be below up to December 2008 and reached to greater than and below during January 2009 – March 2009. SAR values were within the safer limit of less than and RSC was less than meq/l during September 2008 to March 2009. | Study on quantity and quality aspects of the drain water of Nallamada drain in Krishna western delta
