  2. 1. Impact of Water-Level Variations on Slope Stability

    Author : Jens Johansson; Lars Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Waterfront-soil slopes are exposed to water-level fluctuations originating from either natural sources, e.g. extreme weather and tides, or from human activities such as watercourse regulation for irrigation, freshwater provision, hydropower production etc. READ MORE

    Abstract : The scope of this thesis was to identify, describe and quantify important life-history traits for the pseudoannual aquatic plant Ranunculus lingua in different ecological settings, by comparing populations from geographically marginal vs. central habitats. READ MORE

  5. 3. Spatially Distributed Hydrological Modelling : Wetness Derived from Digital Elevation Models to Estimate Peatland Carbon

    Author : Abdulghani Hasan; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; modelling hydrology; Digital elevation models; LiDAR data; topographic wetness index; GIS; permafrost; Stordalen; peatland;

    Abstract : To study the hydrology of peatlands and explore wetness distribution is difficultmainly due to the complexity of the surface of peatlands, and also due to the presence of permafrost underlain peatlands in the arctic regions. I have chosen the area called Stordalen mire in the arctic region in northern Sweden for my study. READ MORE
