  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. Network for Earthquake Engineering Simulation - Wikipedia

    en.wikipedia.org/wiki/Network_for_Earthquake...

    The George E. Brown, Jr. Network for Earthquake Engineering Simulation hosts two geotechnical centrifuges for studying soil behavior. The NEES centrifuge at University of California Davis has radius of 9.1 m (to bucket floor), maximum payload mass of 4500 kg, and available bucket area of 4.0 m2. [ 17 ]

  4. Geotechnical engineering - Wikipedia

    en.wikipedia.org/wiki/Geotechnical_engineering

    Geotechnical centrifuge modeling is another method of testing physical-scale models of geotechnical problems. The use of a centrifuge enhances the similarity of the scale model tests involving soil because soil's strength and stiffness are susceptible to the confining pressure.

  5. Geotechnical investigation - Wikipedia

    en.wikipedia.org/wiki/Geotechnical_investigation

    A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...

  6. Tensiometer (soil science) - Wikipedia

    en.wikipedia.org/wiki/Tensiometer_(soil_science)

    When the soil is wetted flow can also occur in the reverse direction: as water is added to the soil, the vacuum inside the tube pulls moisture from the soil and decreases. When the water pressure in the tensiometer is determined to be in equilibrium with the water pressure in the soil, the tensiometer gauge reading represents the matric ...

  7. Environmental monitoring - Wikipedia

    en.wikipedia.org/wiki/Environmental_monitoring

    The monitoring process itself may be performed using technologies such as remote sensing and geographic information systems (GIS) to identify salinity via greenness, brightness, and whiteness at the surface level. Direct analysis of soil up close, including the use of electromagnetic induction techniques, may also be used to monitor soil ...

  8. Digital footprint - Wikipedia

    en.wikipedia.org/wiki/Digital_footprint

    Interested parties use Internet footprints for several reasons; including cyber-vetting, [15] where interviewers could research applicants based on their online activities. Internet footprints are also used by law enforcement agencies to provide information unavailable otherwise due to a lack of probable cause . [ 16 ]

  9. 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 ...
