  2. Digital soil mapping - Wikipedia

    en.wikipedia.org/wiki/Digital_soil_mapping

    Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...

  3. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    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 soils. Based on this history it has also been called the "Dutch ...

  4. Digital footprint - Wikipedia

    en.wikipedia.org/wiki/Digital_footprint

    The footprint may track the user's IP address, when it was created, where it came from, and the footprint later being analyzed. In an offline environment, administrators can access and view the machine's actions without seeing who performed them.

  5. 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 ...

  6. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy ) within soils.

  7. Soil survey - Wikipedia

    en.wikipedia.org/wiki/Soil_survey

    Soil surveys apply the principles of soil science and draw heavily from geomorphology, theories of soil formation, physical geography, and analysis of vegetation and land use patterns. Primary data for the soil survey are acquired by field sampling and by remote sensing .

  8. Subgrade - Wikipedia

    en.wikipedia.org/wiki/Subgrade

    It is also called formation level. The subgrade provides support to the subbase level and acts as an integral load-bearing layer. Failure of the subgrade can cause depressions and rutting of the upper base and surface courses. These in turn can lead to water pooling in deformations and cause vehicle aquaplaning among other issues. [2]

  9. Patterned ground - Wikipedia

    en.wikipedia.org/wiki/Patterned_ground

    The mechanism of the formation of patterned ground had long puzzled scientists but the introduction of computer-generated geological models in the past 20 years has allowed scientists to relate it to frost heaving, the expansion that occurs when wet, fine-grained, and porous soils freeze.
