WebNov 23, 2024 · Todd (1980) reports values of K z / K r ranging between 0.1 and 0.5 for alluvium and possibly as low as 0.01 when clay layers are present ... which is sometimes … Effective porosity is most commonly considered to represent the porosity of a rock or sediment available to contribute to fluid flow through the rock or sediment, or often in terms of "flow to a borehole". Porosity that is not considered "effective porosity" includes water bound to clay particles (known as bound water) and isolated "vuggy" porosity (vugs not connected to other pores). The effective porosity is of great importance in considering the suitability of rocks or sed… Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, ... Typical bulk density of clay soil is between 1.1 and 1.3 g/cm 3. This calculates to a porosity between 0.58 and 0.51. This seems counterintuitive because clay soils are termed heavy, ... See more Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.
