  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  2. 2. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  3. 3. Landslide Susceptibility Analysis Using Open Geo-spatial Data and Frequency Ratio Technique

    University essay from KTH/Geoinformatik

    Author : TARIK EMRE YORULMAZ; [2022]
    Keywords : Landslides; Hazard mapping; Geographic Information Systems GIS ; Spatial analysis; Frequency ratio FR ; Area Under a Curve AUC ;

    Abstract : Landslide susceptibility maps are useful for spatial decision-making to minimize the lossof lives and properties. There are many studies related to the development of landslidesusceptibility maps using various methods such as Analytic Hierarchy Process, Weight ofEvidence and Logistic Regression. READ MORE

  4. 4. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Lara Sánchez Calderón; [2022]
    Keywords : aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Abstract : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. READ MORE

  5. 5. Dynamic streams in a pre-alpine catchment

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Andreas Sølberg; [2021-07-12]
    Keywords : Temporary streams; Streamflow; Stream mapping; Pre-Alpine catchment; Stream dynamics; Topographic wetness index; Upslope accumulated area;

    Abstract : This thesis aims to investigate the factors controlling the dynamics of temporary streams, i.e., streams that do not flow throughout the year. Temporary stream hydrology is a relative unexplored scientific field. READ MORE
