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

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Anastasia Novikova; [2023]
    Nyckelord :HYDRUS; surface runoff; soil compaction; urban environments;

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

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

    Sammanfattning : 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. LÄS MER

  4. 3. The potential for large-scale implementation of biochar in the agricultural sector : a quantitative study on plant growth in light soils and a qualitative study on the agricultural sector’s perception on biochar

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Mathilda Håkansson; Louise Strömberg; [2022]
    Nyckelord :Transdisciplinary study; Agricultural science; Biochar; Plant growth; Soil properties; Biochar implementation; Perceptions on biochar;

    Sammanfattning : Agricultural activities are collectively one of the largest contributors to accumulation of greenhouse gasses (GHG). At the same time, agriculture is at a risk to be affected extensively by climate change. Concurrently, in conventional agriculture GHG emissions have become inevitable to maintain efficiency.

  5. 4. Water quality and organic matter linkages in waters draining arable fields

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Adam Eriksson; [2021]
    Nyckelord :Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Sammanfattning : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. LÄS MER

  7. 5. The Effects of Sensor Fusion on Localisation in a Sparse, Outdoor Environment

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Kayla Kearns; [2020]
    Nyckelord :;

    Sammanfattning : This thesis compares the results of a localisation algorithm for a mobile robot in both a sparse and a densely featured environment whilst varying key parameters. The software and hardware required to enable the mobile robot to localise itself in the sparsely featured, GPS-denied, outdoor environment is described. LÄS MER
