  2. 16. Urban Snowmelt Processes: Modelling and Observation

    Author : Annette Semadeni Davies; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; energy; runoff; snow properties; heterogeneity; hydrological modelling; Urbanisation; snowmelt; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. READ MORE

  4. 17. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

    Author : Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. READ MORE

  5. 18. On leachate emissions from municipal solid waste

    Author : Martijn van Praagh; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; Miljöstudier; Environmental studies; Environmental Impact; heavy metals; Organic carbon; teknisk geologi; Hydrogeologi; geographical and geological engineering; teknisk geografi;

    Abstract : When attention is drawn to the recovery of resources within waste, the amount and types of waste disposed of at landfills change. A waste management system based on separate kerbside collection, sorting, recycling, and pretreatment with material and/or energy recovery produces new residues, which finally end up at landfills.

  6. 19. Biogas generation in landfills : equilibria, rates & yields

    Author : Mattias Åkesson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; model; limitation; volatile fatty acids; kinetics; biogas; thermodynamics; methane; Landfill; test cell; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. READ MORE

  7. 20. Unsaturated Solute Transport in a Semiarid Catchment - Nonlinear Analyses and Modelling

    Author : Pernilla Öhrström; Avdelningen för Teknisk vattenresurslära; []
    Keywords : 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;

    Abstract : 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. READ MORE
