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

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

   Author : Walter Gezelius Gezelius; [2024]
   Keywords : Restoration; Environmental flows; riparian vegetation;

   Abstract : 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. 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. CFD-modeling of labyrinth weir flood discharge with ice cover

   University essay from KTH/Betongbyggnad

   Author : Erik Isberg; [2023]
   Keywords : ;

   Abstract : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. READ MORE

5. 4. Hunting Hotspots - A framework to assess the effectiveness of using environmentally extended input-output models as a method to identify CO2-eq hotspots in the upstream supply chain of a company

   University essay from Lunds universitet/LUCSUS

   Author : Elisa Anni Bauer; [2023]
   Keywords : GHG emissions; Effectiveness; Hotspot analysis; Environmentally Extended Input-Output; Sustainability Science; Social Sciences;

   Abstract : Industry’s indirect upstream greenhouse gas (GHG) emissions contribute significantly to climate change. To identify and reduce them, some companies conduct a hotspot analysis using an environmentally extended input-output (EEIO) model (often utilizing EXIOBASE database). READ MORE

6. 5. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : John Bradley; Miranda Carlström; [2023]
   Keywords : Capacitive deionization; Faradaic reactions; Flow-through CDI; Upstream anode; Downstream anode; Desalination Performance; pH fluctuations;

   Abstract : Capacitive Deionization (CDI) is an energy-efficient desalination technology that utilizes an electric field to extract ions from water. Flow-through CDI systems show potential for superior desalination performance compared to traditional flow-by CDI; however, they face the challenge of increased occurrence of Faradaic reactions, leading to undesired by-products and reduced energy efficiency.
