  1. 6. Resistance of Clay Brick Masonry Façades to Wind-Driven Rain : Repointing of Eroded Mortar Joints

    Författare :Mohammad Kahangi; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay brick masonry façade; wind-driven rain; water absorption; water penetration; damp patches;

    Sammanfattning : Clay brick masonry façades are commonly used due to their high-performance durability. However, exposure to climate agents such as wind-driven rain (WDR), freeze-thaw cycles, and wind abrasion cause deterioration of masonry façades over time. LÄS MER

  3. 7. Soil Salinity and Crop Yield at El-Salam Canal Area, Egypt

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; El-Salam Canal; Egypt; Salinity; Crop yield; Arid;

    Sammanfattning : Soil salinity and solute movements through the soil are considered the most important challenge facing agriculture in Arid and Semiarid regions (e.g., Egypt). LÄS MER

  4. 8. Modeling stormwater transport through unsaturated green roof substrates

    Författare :Kaj Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; Lattice Boltzmann; porous media; CFD; saturation; multiphase; Green roofs;

    Sammanfattning : In recent decades there has been an increase in research regarding green roofs and similar technologies. This increased interest is driven by the requirements of urban development and its effects both on humans and the environment. LÄS MER

  5. 9. Unsaturated Solute Transport in a Semiarid Catchment - Nonlinear Analyses and Modelling

    Författare :Pernilla Öhrström; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; unsaturated zone; Hydrogeology; geographical and geological engineering; solute transport; scaling; soils; semiarid regions; heterogeneity; preferential flow; fractals;

    Sammanfattning : Unsaturated solute transport is highly variable and therefore difficult to predict. In semi-arid areas, where water resources are limited, the presence of macropores is of great importance for crop production. The bromide ion (Br-) and dye tracers are useful for studies of water movement. LÄS MER

  7. 10. Towards sustainable solid waste management in Jordan

    Författare :Mohammad Aljaradin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Solid Waste Management; Public Participation; Recycling; Landfilling; Jordan;

    Sammanfattning : Jordan is a country with a growing population that is undergoing rapid modernization. The increased volume of solid waste and associated logistical difficulties, the steady growth in the cost of waste management and the risk to human health are sources of concern. LÄS MER
