7 SOIL PERMEABILITY AND DRAINAGE COEFFICIENT OF PERMEABILITY CM/S (LOG SCALE) Drainage property Good drainage Poor drainage Practically impervious Application in earth dams and dikes Pervious sections of dams and dikes Impervious sections of earth dams and dikes Type of soil Clean gravel Clean sands, Clean sand and gravel mixtures Very fine sands, organic and inorganic silts, mixtures of sand, silt, and clay glacial till, stratified clay deposits, etc. Impervious soils e.g., homogeneous clays below zone of weathering Impervious soils which are modified by the effect of vegetation and weathering; fissured, weathered clays; fractured OC clays Direct determination of coefficient of permeability Direct testing of soil in its original position (e.g., well points). If properly conducted, reliable; considerable experience required. Constant Head Permeameter; little experience required. (Note: Considerable experience also required in this range.) Constant head test in triaxial cell; reliable w ith experience and no leaks. Reliable; Little experience required Falling Head Per meameter; Range of unstable permeability;* much experience necessary to correct interpretation Fairly reliable; considerable experience necessary (do in triaxial cell) Indirect determination of coefficient of permeability Computat ion: From the grain size distribution (e.g., Hazen s formula). Only applicable to clean, cohesionless sands and gravels Horizontal Capillarity Test: Very little experience necessary; especially useful for rapid testing of a large number of samples in the field w ithout laboratory facilities. Computations: from consolidation tests; expensive laboratory equipment and considerable experience required *Due to migration of fines, channels, and air in voids. From FHWA IF Evaluation of Soil and Rock Properties. Slide 7 of 14
8 FACTORS AFFECTING PERMEABILITY is not a fundamental soil property but depends upon a number of factors: Particle size distribution Particle shape and texture Mineralogical composite Invariable for a given soil Void ratio Degree of saturation Soil fabric Dependent upon placing and treatment of the soil Nature of fluid Type of Flow Temperature Relate to the permeability Temp.
