Permeability is one of the most important and frequently used properties of soils. Grain size distribution and density are two important factors influencing the permeability of sandy soils. Although the relationships between grain size distribution and permeability has been quantified in previous studies, the influenced of density has not been quantified. The objective of this project is to investigate the quantitative relationships between permeability and grain size distribution indices such as effective particle size (D10), coefficient of uniformity (Cu), coefficient of curvature (Cc), percentage of coarse sand fraction by weight of sample (%C), percentage of medium sand fraction by weight of sample (%M), and percentage of fine sand fraction by weight of sample (%F) to determine whether these relationships could be used for reliable estimates of permeability. Six samples of sandy soils, ranging from well graded to poorly graded, will be tested in the laboratory to determine their grain size distribution. The D10, Cu, Cc, %C, %M, and %F values for each soil will be calculated from the grain size distribution plots. Five replicate samples of each soil will be prepared at varying density values and tested for permeability using the constant head permeability test.
