  1. 1. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

    Författare :Estevao Pondja; [2017-05-08]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coal mining; acid mine drainage; mine water treatment; climate change; low-cost adsorbent;

    Sammanfattning : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. LÄS MER

  2. 2. Environmental Modelling Learning from Uncertainty

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

    Sammanfattning : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. LÄS MER

  3. 3. Uncertainty, variability and environmental risk analysis

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Monika Filipsson; Tomas Öberg; Bo Bergbäck; Lars Rosén; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Contaminated land; exposure assessment; exposure factors; risk analysis; risk perception; uncertainty; variability; probabilistic risk assessment; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

    Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER

  4. 4. The Meaning of Environmental Management : An Interpretive Study of Managing Emergent or Evolutionary Environmental and Energy Strategy

    Detta är en avhandling från IIIEE, Lund University

    Författare :Thomas Parker; [2016-12-02]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental Management Systems; Emergent strategy; Interpretive Research; Change; Complexity; Contingency; Energy Management; Management of meaning; Environmental Management Systems; Emergent strategy; Contingency; Change; Complexity; Energy Management; Management of meaning;

    Sammanfattning : Because of the vital roles of industry in sustainable development, it is essentialthat environmental management is effective in preventing pollution. To this end,environmental management systems have been implemented to a growing extent inindustry. Moreover, this Ph.D. LÄS MER

  5. 5. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

    Detta är en avhandling från IIIEE, Lund University

    Författare :Jonas Sundell; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

    Sammanfattning : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. LÄS MER
