Abstract

Permeability simply implies the capability of the soil to allow the flow of water through pores of the soil. Permeability depends on a multitude of factors which include void ratio, size of particles, shape of particles, water content and degree of compaction. When the flow is normal to the bedding plane, permeability parameters show significant variations and complications owing to the mutual interaction among different soil layers and their relative position in the deposit. Through this investigation, the permeability characteristics of layered soil deposit when the flow is perpendicular to the bedding plane, also factors and associated mechanisms controlling such flows has been analyzed. In this study, three distinct samples were collected from three locations in Srinagar city and the respective soils includes sand, clay, and silt. The coefficient of permeability (k) for each soil has been determined and also the coefficient of permeability is calculated experimentally by varying the arrangement and proportion of above-mentioned soil layers. After the determination of the coefficient of permeability in all arrangements, it has been found that the experimental permeability was considerably lesser than theoretical permeability. It has been observed that if the bottom layer has less permeability than the top layer, the equivalent permeability of the deposit have been found to be more when compared to the isolated permeability of the bottom layer. Also, if the bottom layer is more pervious than the top layer the permeability of deposit is less as compared to the individual permeability of the bottom layer. Considering the previous work in this area, results obtained in this investigation were quite consistent and had a fair degree of accuracy.
