Impact of Municipal Leachate on Permeability Characteristics for Stratified Soil
Priyanka P,  Lokeshappa B
Permeability of permeable media is a significant property which relies on different properties of soil. The main aim of intended work is to assess the characteristics of stratified soil with respect to index and engineering properties after passing the leachate through the stratified bed. The process mainly consists of clayey gravel bed, silty sand bed and stratified soil bed with remoulded soil profile is constructed to correlate the vertical flow to the soil bed. From the present dissertation work it can be concluded that by passing leachate through the soil, the permeability co-efficient increases and reaches maximum of 2.89×10-3 cm/sec, 7.32×10-3cm/sec and 4.35×10-3 cm/sec at 4 hours for silty sand, clayey gravel and stratified soil respectively, after the permeation point the coefficient of permeability decreases and reaches the maximum level at 24 hours of 2.46×10-3 cm/sec, 5.756×10-3 cm/sec and 3.26×10-3 cm/sec for respective soil beds. The soil properties such as specific gravity, liquid limit, plastic limit, free swelling index, shear strength were found to decrease in contaminated soil when compared to uncontaminated soil.
