  2. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Physical properties of soil. The physical properties of soil, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity. [1] Soil texture is determined by the relative proportion of the three kinds of soil mineral particles ...

  3. Soil thermal properties - Wikipedia

    en.wikipedia.org/wiki/Soil_thermal_properties

    While related to soil temperature, it is more accurately associated with the transfer of energy (mostly in the form of heat) throughout the soil, by radiation, conduction and convection. The main soil thermal properties are. Volumetric heat capacity, SI Units: J∙m −3 ∙K −1. Thermal conductivity, SI Units: W∙m −1 ∙K −1.

  4. Electrical resistivity tomography - Wikipedia

    2D resistivity inversion of ERT data Deployment of a permanent electrical resistivity tomography profile on a longitudinal section of an active landslide.. Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more ...

  5. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    Symbol used in drawings. Simplified version of a cone penetrometer. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft ...

  6. Unified Soil Classification System - Wikipedia

    en.wikipedia.org/wiki/Unified_Soil...

    The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the ...

  7. Standard penetration test - Wikipedia

    en.wikipedia.org/wiki/Standard_penetration_test

    The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

  8. Electrical resistance survey - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistance_survey

    Electrical resistance surveys (also called earth resistance or resistivity survey) are one of a number of methods used in archaeological geophysics, as well as in engineering geological investigations. In this type of survey electrical resistance meters are used to detect and map subsurface archaeological features and patterning.

  9. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    In heat transfer, thermal engineering, and thermodynamics, thermal conductance and thermal resistance are fundamental concepts that describe the ability of materials or systems to conduct heat and the opposition they offer to the heat current. The ability to manipulate these properties allows engineers to control temperature gradient, prevent ...
