1. 6. Adapting to melting glaciers : how Western Himalayan societies frame climate change and adaptation

   Master-uppsats, SLU/Dept. of Urban and Rural Development

   Författare :Taha Anis; [2022]
   Nyckelord :Adaptation; identity; risk and Information; authority; Himalayas; frame analysis; Gilgit-Baltistan; Pakistan;

   Sammanfattning : The glaciers of the Hindu-Kush Himalayas region flow into 10 major river basins and sustain nearly 2 billion people, with 250 million being directly dependent on them for freshwater sources while a further 1.65 billion rely on their outflows. LÄS MER

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

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

   Sammanfattning : 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. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Feixiong Qu; [2021]
   Nyckelord :;

   Sammanfattning : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. LÄS MER

5. 9. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

   Sammanfattning : 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.

7. 10. Modelling of water and material transport in River Storån to Lake Bolmen

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Imjal Sukupayo; [2021]
   Nyckelord :Brownification; Water Color; Dissolved Organic Matter; Discharge; hydraulic analysis; Tracer Analysis; Dispersion coefficient; Advection and Diffusion; Bolmen Lake; Storån River; Technology and Engineering; Earth and Environmental Sciences;

   Sammanfattning : 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. LÄS MER
