Abstract :

Parameters such as Permeability Index (PI), Kelly’s Ratio (KR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC) and Sodium Absorption Ratio (SAR) are considered for the Study. In pre monsoon of 2009 PI varies from 58.7 to 62.7 with mean 59.9; KR varies from 0.7 to 0.8 with 0.8 mean; SSP varies from 42.4 to 44.2 with mean 43.8; RSC differ from –1.8 to –1.2 with an average of –1.5; SAR varies from 3.7 to 5.7 with an average of 5.0; In pre monsoon of 2013 PI varies from 45.7 to 50.3 with mean 47.1; KR varies from 0.5 to 0.6 with 0.6 mean; SSP varies from 35 to 35.2 with mean 35.1; RSC differ from – 4.8 to –3.0 with an average of – 4.0; SAR varies from 1.5 to 2.3 with an average of 1.9; In post monsoon of 2009 PI varies from 55.5 to 62.1 with mean 57.3; KR varies from 0.7 to 0.71 with 0.7 mean; SSP has 41.1; RSC differ from –3.4 to –1.6 with an average of – 2.7; SAR varies from 3.3 to 4.8 with an average of 4.3; PI varies from 58.7 to 62.7 with mean 59.9; KR varies from 0.7 to 0.8 with 0.8 mean; SSP varies from 42.4 to 44.2 with mean 43.8; RSC differ from –1.8 to –1.2 with an average of –1.5; SAR varies from 1.7 to 2.5 with an average of 2.3.
