  1. 11. Land cover classification using machine-learning techniques applied to fused multi-modal satellite imagery and time series data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Anastasia Sarelli; [2024]
    Nyckelord :Geography; GIS; Land Cover Classification; Landsat; Machine Learning; Earth and Environmental Sciences;

    Sammanfattning : Land cover classification is one of the most studied topics in the field of remote sensing, involving the use of data from satellite sensors to analyze and categorize different land surface types. There are numerous satellite products available, each offering different spatial, spectral, and temporal resolutions. LÄS MER

  3. 12. Assessment of Climate Change Impact on Rainfed Barley Production in the Mediterranean Basin : The Almeria province case study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Francesco Saretto; [2024]
    Nyckelord :Barley; Rainfed; Climate Change; AquaCrop; AquaCrop-OSPy; Mediterranean; Climate Change Adaptation; Crop Modeling; Agriculture; Irrigation;

    Sammanfattning : The Mediterranean basin is widely recognized as a climate change hotspot, with climate models projecting increasingly warmer and drier conditions that will impact local ecosystems, communities, and economies. Agriculture will be among the most affected sectors, with harsher conditions for crops’ growth, greater water needs, and lower yields. LÄS MER

  4. 13. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Walter Gezelius Gezelius; [2024]
    Nyckelord :Restoration; Environmental flows; riparian vegetation;

    Sammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER

  5. 14. Hur avrinningskoefficienten varierar med återkomsttid - En jämförelse mellan fyra olika områden i Sverige

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Nina Enger; [2024]
    Nyckelord :Runoff coefficient; Return period; Modelling; MIKE ; Floodings; Technology and Engineering;

    Sammanfattning : As climate change progresses, heavy rainfall in Sweden is becoming more frequent and intense, coinciding with an increase in impermeable surfaces in urban areas. This raises the risk of flooding as drainage networks may exceed their capacity due to increased runoff. LÄS MER

  7. 15. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Merhawi Belai; [2024]
    Nyckelord :nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Sammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER
