  1. 1. Environmental Modelling Learning from Uncertainty

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

    Författare :John M. Juston; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; 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

  2. 2. Groundwater resources in hard rock coastal terrains Insights into heterogeneity and spatial variability

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

    Författare :Robert Earon; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Crystalline Rock; Groundwater Balance; Kinematic porosity; Groundwater Recharge; Water Security; Coastal Aquifer; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. LÄS MER

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

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

    Författare :Estevao Pondja; Lund University.; Lunds universitet.; [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

    Detta är en avhandling från IIIEE, Lund University

    Författare :Thomas Parker; Lund University.; Lunds universitet.; [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. Uncertainty, variability and environmental risk analysis

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

    Författare :Monika Filipsson; Linnéuniversitetet.; [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
