There are two general types of permeability test methods that are routinely performed in the laboratory: (1) the constant head test method, and (2) the falling head test method. The constant head test method is used for permeable soils (k>10-4 cm/s) and the falling head test is mainly used for less permeable soils (k<10-4 cm/s). A model was proposed to predict the permeability of granular soil with various gradations. The pore size distribution for different particle sizes was determined by considering different particle combinations and occurrence probabilities, which was then used in the fractal and capillary model for predicting soil permeability. The proposed model was verified by .
