1. 16. Porous pavement in a cold climate

   Författare :Magnus Bäckström; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Local disposal of stormwater can be achieved by using porous pavements instead of impermeable pavements with conventional stormwater pipes and manholes. The objective of this thesis was to analyse the performance of porous pavements during freezing, thawing, and snowmelting conditions in order to evaluate if the porous pavement is suitable for stormwater management and road construction in cold climate regions.

3. 17. Kvinna i byggbranschen : civilingenjörers erfarenheter ur genusperspektiv

   Författare :Annicka Cettner; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : This thesis is a gender analysis based on women's experiences of working as engineers in the construction industry. It focuses on the women's working conditions, and their possibilities to make a career in construction. The question is why many women engineers choose to leave construction after an expensive education. LÄS MER

4. 18. Overcoming inertia to sustainable stormwater management practice

   Författare :Annicka Cettner; Sarah Bell; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : In Sweden, there is a growing receptivity for change to more sustainable stormwater practices using green infrastructure approaches. Unlike piped drainage systems they can have multiple benefits in use including flood control, pollutant removal and can add to the quality of urban space supporting green infrastructure through irrigation and providing cooling and an additional water source for supply.

5. 19. Seasonal turnover in groundwater

   Författare :Maria Engström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : This Licentiate Thesis presents a new approach of understanding leakage in agricultural land. Former studies concentrate on long term measurement of different pollutants in nearby watercourses and streams. The new approach is so far only numerically performed, but will soon be complemented by laboratory tests and field measurements. LÄS MER

7. 20. Stormwater bioretention: Pollutant occurrence and accumulation in filter materials and forebays

   Författare :Robert Furén; Godecke-Tobias Blecken; Jes Vollertsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioretention; Biofilter; storwater; quality; treatment; filter material; forebay; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : Urban areas are affected by anthropogenic activities and produce pollutants that are transported to recipients and receiving waters during precipitation. Untreated stormwater runoff is a main driver of environmental degradation, and the interest in stormwater quality treatment has increased with the awareness of stormwater pollution. LÄS MER
