  1. 11. Coupled processes in seasonally frozen soils : Merging experiments and simulations

    Författare :Mousong Wu; Per-Erik Jansson; Bjorn Klove; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Frozen soil; Coupled transport; Energy balance; Uncertainties; Merged study; 冻土；水热盐运移；耦合关系；水热平衡；不确定性; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Soil freezing/thawing is of importance in the transport of water, heat and solute, with coupled effects. Due to complexity in soil freezing/thawing, uncertainty could be influential in both experimentation and simulation work in frozen soils. LÄS MER

  5. 14. Impacts of land use change on river streamflow and water quality in a semi-arid catchment : assessment of a catchment under rapid and uncontrolled urbanisation

    Författare :Benjamin Gossweiler; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The ongoing degradation of water quality and streamflow in rivers and streams worldwide is mainly due to human action through global land use change, particularly urbanisation. Population growth and economic development are major drivers of urbanisation, which causes environmental problems such as high water demand and solid waste and wastewater generation. LÄS MER

  7. 15. Soil compaction: effects on soil hydraulic properties and preferential water flow

    Författare :Mona Mossadeghi Björklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. LÄS MER
