1. 6. Restaureringens effekt på öringpopulationen

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Ola Carlström; Sebastian Dagman; [2022]
   Keywords : restaurering; flottning; öring; älv; bäck;

   Abstract : Until the 1970s, rivers in Sweden were used for timber floating. In order for the floating to be as efficient as possible, with a minimum of timber getting stuck, many rivers were cleared. Large rocks and boulders were removed from the main channel and tributaries, backwaters and shallow areas were secluded. READ MORE

3. 7. Sediment Transport and Erosion in Viskan River, South Sweden

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Siyuan Wang; [2022]
   Keywords : HEC-RAS; cross section; erosion; sediment transport; deposition; Technology and Engineering;

   Abstract : This master thesis study presents the results of sediment transport analysis along Viskan, located in south Sweden. The main processes cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to observed eroded locations, and finally comparison of different transport functions how they influence the results.

4. 8. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
   Keywords : HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

   Abstract : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

5. 9. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Oskar Evert Johansson; [2021]
   Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

   Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

6. 10. Digitizing and Mapping Channel Heads Across Various Forested Regions in Sweden Using a High-Resolution DEM : A Regional Analysis of How Landscape Properties Influencing Channel Head Initiation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Amanda Jarefjäll; [2021]
   Keywords : ;

   Abstract : Acting as a hydrological link between the terrestrial landscape and the larger downstream river network, channel heads and their immediate headwaters are essential geomorphological features in our landscape. Not only due to their ability to transport water and sediment and cycling of nutrients, but as an important component for ecosystem productivity and aquatic habitats. READ MORE
