  1. 1. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nikolaos Kouskoulis; [2023]
    Keywords : Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Abstract : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. READ MORE

  3. 2. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling

    University essay from

    Author : Anastasia Novikova; [2023]
    Keywords : HYDRUS; surface runoff; soil compaction; urban environments;

    Abstract : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. READ MORE

  4. 3. The Influence of Infiltration Capacity and Antecedent Soil Moisture Conditions on Urban Pluvial Flooding

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Disa Barkefors; [2023]
    Keywords : Urban pluvial flood; 2D modelling; MIKE ; urban green area; soil moisture; Chicago Design Storm;

    Abstract : Urban pluvial floods occur during extreme rain events and both occurrence and magnitude of these floods are expected to increase. Preserving or constructing green areas in urban areas has been shown to mitigate and control these floods. READ MORE

  5. 4. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Oskar Ahlstedt; [2022]
    Keywords : Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Abstract : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. READ MORE

  6. 5. Efficiency of sustainable urban drainage systems during flash floods

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Snærós Axelsdóttir; [2022]
    Keywords : Bioretention Cell; Rain Garden; Infiltration Trench; Green Roof; Permeable Pavement; Stormwater runoff; Storm Water Management Model;

    Abstract : As the world’s population is migrating more into urban areas, landcover changes follow. Natural pervious areas are being converted to impervious areas, which when subjected to rain generates more stormwater runoff. READ MORE
