  • Geostatistics regains interest in the characterization of chemical soil pollutions

    To evaluate the pollution impact, such characterization is usually based on various data that should be interpreted and analyzed with an estimation of related uncertainties. Geostatistics has been suitably applied in this framework for about fifteen years. Several Ph.D. theses have been dedicated to the subject, both for chemical and radiological pollution (see for instance ...

  • The critical importance of site characterization in remediation design

    Design is a traditional task common to all engineering fields although most engineers do not have to deal with the heterogeneous properties of materials as is the case in site remediation, mining, geotechnical engineering, etc.  A structural engineer can specify properties of steel or reinforced concrete and an electronics engineer can specify the physical properties of transistors, ...

  • Soil experts recreate soils from Mars

    Soil experts from Cranfield University have developed a replica soil for Mars in a project for the European Space Agency (ESA) to help maximise the performance of the next robotic rovers to be sent to the planet. The ‘soil surrogate’ is one of a number of soil types characterized by the current NASA Mars Exploration Rovers (MER), Spirit and Opportunity, which were sent to Mars in ...

  • Measuring global soil changes

    Global change is increasingly affecting important terrestrial ecosystem functions such as the filtering and buffering capacity of soils, the supply of clean water, soil fertility, and consequently, the production of food, feed, and fiber. Recent studies and reports from the United Nations indicate that water and soil resources are both heavily under pressure. Worldwide about 2 billion ha of land ...

  • Soil climate monitoring in Antarctica

    Antarctica, the coldest place on earth, has an area of about 14 million sq. km. About 98% of the continent is covered by ice, which averages about 2100 m thick. This vast ice sheet contains the earth’s largest fresh water reserve. Of the ice-free ground, only 0.3% is available for soils to form. Currently there are seven soil climate stations in Antarctica, which monitor a range of ambient ...

  • Precompression stress in soils

    The precompression stress as a factor to assess the mechanical stability of soils is predictable by using pedotransfer functions. Over the past decades arable soils have been deteriorated because of the heavy machinery on the farm. Increase loads enhance subsoil compaction which is mostly irreversible. As a consequence of this deformation, the soil productivity decreases while the erodibility ...

  • Track soil particles moving through watershed

    Soil erosion of croplands, rangelands, and urban areas is one of the most common problems that negatively affects the environment. Soil particles carried by rainwater along slopes may transport a variety of harmful agricultural and industrial chemicals, cause the soil to lose fertility, and inundate streams. Quantifying the movement of soil through watersheds is a complex task, which requires ...
