6. Impact of Extreme River Flows on Bridges An Application to River Lagan in Ljungby Municipality, Sweden Using HEC RAS
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : The role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour.

7. Sediment Transport and Erosion in Viskan River, South Sweden
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : 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.

8. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : 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.

9. Modelling of water and material transport in River Storån to Lake Bolmen
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. READ MORE

10. GIS-based approach to estimate direct economic damages of fluvial flooding under various future scenarios: A case study of the Neckar river basin (Germany)
University essay from Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetAbstract : Fluvial floods can cause significant damages to inundated assets. The frequency and magnitude of fluvial floods are related to precipitation amounts, which are expected to change throughout the 21st century due to global warming. READ MORE
