  1. 1. Näringsförluster från sju jordbruksområden nära Mälaren

    University essay from SLU/Dept. of Soil and Environment

    Author : Sally Karlsson Bondesson; [2024]
    Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

    Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

  3. 2. Impact of wetland restoration on river discharge - A case study of Bråån, Skåne, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ardis Luda; [2023]
    Keywords : wetlands; wetland restoration; HYPE model; river discharge; Sweden; land use change; flooding; hydrological modeling; Earth and Environmental Sciences;

    Abstract : Land use change is a factor not often considered when modeling river discharge in regard to future flood risk. The restoration of wetlands is an ongoing land use change which affects water storage capacity in the soils of a catchment and could lead to lower flows in rivers. READ MORE

  4. 3. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilía Sól Gudgeirsdóttir; [2023]
    Keywords : SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Abstract : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. READ MORE

  5. 4. 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

  6. 5. Mapping Fire Salamander (Salamandra salamandra) Habitat Suitability in Baden-Württemberg with Multi-Temporal Sentinel-1 and Sentinel-2 Imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Andreas Eriksson; [2022]
    Keywords : Geography; GIS; Habitat Suitability; Remote Sensing; Image Classification; Earth and Environmental Sciences;

    Abstract : Remote sensing image classification is used in land cover, forest type and tree species classifications but rarely considered for habitat suitability modelling of animal and plant species. It is instead common that land cover products derived from remote sensing data are used in these modelling problems, even though satellite imagery can provide more detailed information. READ MORE
