1. 1. Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden : Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Hammad Masood; [2022]
   Keywords : Chernobyl incident; Sweden; radio-cesium; contamination; terrestrial environment; quatic environment;

   Abstract : Technological advancement and the quest for power have gradually contaminated our environment, as industrialization, agriculture, and nuclear activities progressed. In the year 1986, a terrible nuclear incident occurred in Ukraine, in which the nuclear reactor exploded. READ MORE

3. 2. Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Anna Stella Guðmundsdóttir; [2021-03-18]
   Keywords : ;

   Abstract : The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing Firkanten Formation, has been the subject of study for researchers in the past but little focus has been on the northeast edge of the basin until now. Due to the economic potential of the coal seams in the formation, the Norwegian mining company, Store Norske Spitsbergen Grubekompani (SNSG), has for several years conducted core drilling in key locations in basin, and for decades, they have given an access to their core material to researchers.

4. 3. 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. 4. Phosphorus accumulation in a free water surface wetland discharging into the Baltic Sea

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Manuela Watschka; [2021]
   Keywords : free water surface wetland; phosphorus accumulation; internal loading; sediment accumulation;

   Abstract : Eutrophication has been an issue of the Baltic Sea for a long time, causing de-creased water clarity due to enhanced growth of algae and oxygen depletion dur-ing the decomposition of algae. The study investigated the free water surface wetland Vilhelmsberg that treats agricultural runoff before the water reaches the Baltic Sea. READ MORE

6. 5. Gas Emissions from Contaminated Fibrous Sediments in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fredrik Collin; [2020]
   Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

   Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. READ MORE
