  1. 1. Cost management for underground infrastructure projects : a case study on cost increase and its causes

    Författare :Peter Lundman; Stuart D. Green; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Extensive investments in infrastructure for transportation are currently being carried out in Sweden. A substantial part consists of underground road- and railway projects. LÄS MER

  3. 2. Green Urban Drainage Infrastructure : Hydrology and Modelling of Grass Swales

    Författare :Hendrik Rujner; Maria Viklander; Günther Leonhardt; Jiri Marsalek; Barraud Sylvie; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : The management of urban runoff has evolved along with the advancement of understanding of runoff environmental impacts. Besides the impacts on water quality in the receiving waters, the impacts on the urban hydrologic regime include reduced infiltration by the sealing of pervious land, reduced evapotranspiration by removal of vegetation, and the resulting increase of stormwater runoff peaks and volumes causing flooding, and ultimately degradation of receiving waters.

  4. 3. Peasant proudction and limits to labour Thyolo and Mzimba Districts in Malawi, mid-1930s to late-1970s

    Författare :Erik Green; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; production; peasant; Malawi; Africa; accumulation; agriculture; Ekonomisk och social historia;

    Sammanfattning : The persistence of a low productive peasant sector in sub-Saharan Africa is one of the enigmas of development research. This study approaches the question from a historical perspective by analysing the paths of agrarian change in two contrasting cases in Malawi from the mid-1930s to the late 1970s. LÄS MER

  5. 4. Biodiversity and green infrastructure in urban landscapes

    Författare :Ulf G. Sandström; Per Angelstam; Abdul Khakee; Kjell Nilsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi; Birds in cities; Communication between sciences; Conservation planning; Landscape ecology; Swedish green planning; Urban green space; Urban planning; Urban vegetation; Biologi med ekologisk inriktning; Biology; Biologi; Biologi med ekologisk inriktning;

    Sammanfattning : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. LÄS MER

  7. 5. Blue-green stormwater systems for citywide flood mitigation : Monitoring, conceptualization, modeling, and evaluation

    Författare :Salar Haghighatafshar; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blue-green measures; drainage system; flooding; flood mitigation; hydrodynamic modeling; rainfall-runoff; stormwater;

    Sammanfattning : Considering the growth in urbanization, leading to an increase in impervious surfaces, and the changing climate, enhancing the intensity and frequency of rainfall events, existing urban drainage networks—separate or combined sewer systems—are presumed to face substantially elevated hydraulic loads, causing pluvial floods in urban areas. There are several ways to address these challenges. LÄS MER
