  2. 1. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment

    Author : Alaleh Ziagharib; Christian Maurice; Josef Macsik; Qi Jia; Jan Laue; Bo Vesterberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur-rich soil; Mixing; Sampling; Unconfined compressive strength; stabilization; Porosity; Water content; Consistency limits; Geoteknik; Soil Mechanics;

    Abstract : Sulfide soils are silty soils, often found in saturated conditions, under the groundwater level. Characteristics of these soils, including particle size distribution and consistency limits along with chemical composition and environmental properties, cause excavation to be necessary for construction purposes.

  5. 3. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land

    Author : Pär-Erik Back; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty; decision analysis; risk; sampling; data worth; soil sampling; contaminated land;

    Abstract : Contaminated soil and groundwater is a problem that has received increased attention in the last decade. Decision-making about investigation strategies, protective actions, and remedial actions is based on sparse and uncertain information, primarily data of contaminant concentrations and geological information.

  6. 4. Value of Information Analysis for Site Investigations in Remediation Projects

    Author : Pär-Erik Back; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uncertainty; value of information; soil; decision analysis; sampling; remediation; contaminated land; site investigation;

    Abstract : Site investigations of contaminated land are associated with high costs. From a societal point of view, just enough economic resources should be spent to allow societys limited resources to be allocated optimally to sustainable development. READ MORE

  7. 5. Soil Degradation of Raised-beds on Orchards in the Mekong Delta Field and Laboratory Methods

    Author : Quang Pham Van; Per-Erik Jansson; Khoa Le Van; Ingmar Messing; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; citrus orchards; nutrient; soil fertility; soil strength; soil degradation; alluvial soil; Mekong delta;

    Abstract : Soil degradation is a complex process which may occur anywhere and at any time. It directly affects the physical, chemical and biological processes within the soil profile. Soil degradation can either be as a result of natural hazards or due to manmade actions, such as mismanagement on cropping patterns, soil preparation and cultivation practices. READ MORE
