  2. Porosity - Wikipedia

    en.wikipedia.org/wiki/Porosity

    Porosity is a fraction between 0 and 1, typically ranging from less than 0.005 for solid granite to more than 0.5 for peat and clay. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain.

  3. Pore space in soil - Wikipedia

    en.wikipedia.org/wiki/Pore_space_in_soil

    The porosity is a measure of the total pore space in the soil. This is defined as a fraction of volume often given in percent. The amount of porosity in a soil depends on the minerals that make up the soil and on the amount of sorting occurring within the soil structure.

  4. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  5. Aquifer properties - Wikipedia

    en.wikipedia.org/wiki/Aquifer_properties

    where is void ratio, is porosity, V V is the volume of void-space (air and water), V S is the volume of solids, and V T is the total or bulk volume of medium. [1] The significance of the porosity is that it gives the idea of water storage capacity of the aquifer. Qualitatively, porosity less than 5% is considered to be small, between 5 and 20% ...

  6. Soil structure - Wikipedia

    en.wikipedia.org/wiki/Soil_structure

    Soil structure describes the arrangement of the solid parts of the soil and of the pore spaces located between them (Marshall & Holmes, 1979). [1] Aggregation is the result of the interaction of soil particles through rearrangement, flocculation and cementation.

    en.wikipedia.org/wiki/Soil

    Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  8. Soil morphology - Wikipedia

    en.wikipedia.org/wiki/Soil_morphology

    The table below displays the deal bulk densities that both allow and restrict root growth for the three main texture classifications. The porosity of a soil is an important factor that determines the amount of water a soil can hold, how much air it can hold, and subsequently how well plant roots can grow within the soil. [14] Soil porosity is ...

  9. Pore structure - Wikipedia

    en.wikipedia.org/wiki/Pore_structure

    Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
