1. 1. Sensitivity of Norway Spruce (Picea abies) to inundation.

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

   Author : Whitney Cleopatra Vlahakis; [2023]
   Keywords : Inundation; riparian zone; spruce seedlings; restoration; mortality;

   Abstract : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. READ MORE

3. 2. 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

4. 3. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Ellen Lundin; Lovisa Liljenberg; [2023]
   Keywords : LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

   Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE

5. 4. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

   University essay from Uppsala universitet/Datalogi

   Author : Lovisa Olsson; Julia Hellström; [2023]
   Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

   Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

6. 5. Kan möjligheten till rörelse i olika kalvhållningssystem påverka tjockleken på klövens elastiska puta? : en pilotstudie

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Andrea Carlsson; [2023]
   Keywords : elastiska putan; rörelsemängd; mjölkraskalv; klövhornsskador; sulblödning; klövsulesår;

   Abstract : Syftet med studien var att undersöka om möjligheten till rörelse i olika kalvhållningssystem kan påverka utvecklingen av klövens stödjevävnad med fokus på den elastiska putan. Sulblödningar och klövsulesår är två vanliga klövlidanden i mjölkproducerande besättningar. READ MORE
