2. 6. Climate change and urban drainage : future precipitation and hydraulic impact

   Author : Mats Olofsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Increasing global mean temperature influences the hydrologic cycle. In the 21st century, hydrologic change featuring more heavy precipitation events is very likely according to the UN Intergovernmental Panel on Climate Change, IPCC. This change will have a great impact on urban environments and infrastructures. READ MORE

4. 7. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

   Author : Lars-Erik Harderup; Avdelningen för Byggnadsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

   Abstract : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. READ MORE

5. 8. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

   Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

   Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

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

   Author : Salar Haghighatafshar; Avdelningen för kemiteknik; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 10. Urban stormwater systems in future climates : assessment and management of hydraulic overloading

   Author : Karolina Berggren; Adrian Saul; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Increasing global temperatures and tendencies of more frequent extreme weather events have been observed over the recent decades, and the continuation of this trend is predicted by future climate models. Such climatic changes impact on many human activities and hence the interest in, and focus on, climate change has increased rapidly in recent years. READ MORE
