Correlation between infiltration capacity and permeability of soil

Abstract

Infiltration is the surface phenomenon through which water enters the ground. Infiltration capacity of an area depends on various factors, like land use, Texture, Permeability, Soil type among others. Permeability value of surface affects the infiltration largely. In this study double ring infiltrometer is used to accurately estimate the infiltration capacity of open areas in twenty four places of Chandigarh city. Constant head permeability test is used to calculate the permeability value of the soil. On the basis of collected data, a correlation is developed between infiltration and permeability of soil. The statistical significance of the correlation is checked using the regression analysis by plotting different types of trend lines and then best fit line is selected to represent the relationship using a significance value. The correlation coefficient comes out to be +0.91 that means the infiltration and permeability are positively correlated. When the value of permeability increases then the infiltration value is also found out to be increasing. Statistical significance is proved through the logarithmic trend line which has coefficient of determination R 2 value equal to 0.927 which shows it is a good fit.
