  1. 1. Hydraulic Modelling of Eurasian Beaver Structural Modifications: Implications for Evaluating their Contributions to Natural Flood Management in Scotland

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Maja Christina Pitcairn; [2023]
    Keywords : Beaver reintroduction; Scotland; Flood risk; Natural flood management; Hydraulic modelling.; Technology and Engineering;

    Abstract : The concurrent climate and biodiversity crises in Scotland necessitate the exploration of ecosystem-based adaptation to simultaneously address increased flood risk and the loss of native species. This research investigated the contributions of Eurasian beaver reintroductions to natural flood management in Scotland. READ MORE

  3. 2. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. 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. Modelling the risk of rainfall events leading to momentary pollution levels exceeding maximum allowed concentrations - A Swedish case study of urban runoff in the Fyris river

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tove Gannholm Johansson; [2022]
    Keywords : urban runoff; flow; rain event; pollution concentration; EQS; MAC-EQS; dagvatten; flöde; regntillfälle; föroreningskoncentration; MKN; MAC-MKN;

    Abstract : The purpose of this study was (1) to study the proportion (X) of the flow in a watercourse that consists of urban runoff during a rain event and (2) to evaluate the risk that a few chosen pollutants, transported by urban runoff, exceed the maximum allowed concentration in the watercourse according to the environmental quality standards (MAC-EQS). The Fyris river in Uppsala, Sweden, was selected as a case study. 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
