  2. 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.

  3. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    A phase diagram of soil indicating the masses and volumes of air, solid, water, and voids. There are a variety of parameters used to describe the relative proportions of air, water and solid in a soil. This section defines these parameters and some of their interrelationships. [2] [6] The basic notation is as follows:

  4. Hydrolastic - Wikipedia

    en.wikipedia.org/wiki/Hydrolastic

    Hydrolastic is a type of space-efficient automotive suspension system used in many cars produced by British Motor Corporation (BMC) and its successor companies. Invented by British rubber engineer Alex Moulton , and first used on the 1962 BMC project ADO16 under designer Alec Issigonis , later to be launched as the Morris 1100 .

  5. Critical state soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Critical_state_soil_mechanics

    This behavior, critical state soil mechanics simply assumes as a given. For these reasons, critical-state and elasto-plastic soil mechanics have been subject to charges of scholasticism; the tests to demonstrated its validity are usually "conformation tests" where only simple stress-strain curves are demonstrated to be modeled satisfactorily.

  6. 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.

  7. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). [ 1 ] [ 2 ] Accordingly, soil is a three- state system of solids, liquids, and gases. [ 3 ]

  8. File:Soil-phase-diagram.svg - Wikipedia

    en.wikipedia.org/wiki/File:Soil-phase-diagram.svg

    Soil phase diagram showing soil composition. V is for volume, M is for mass. Subscripts s, w, and a stand for soil particles, water and air respectively. Subscripts v and t stand for voids and total respectively. Date: 9 June 2010, 11:05 (UTC) Source: Soilcomposition.png: Author: Derivative work: 5d7ygtr09h; Sjhan81

  9. Water retention curve - Wikipedia

    en.wikipedia.org/wiki/Water_retention_curve

    Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
