  1. 1. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Alexander Lindblad; [2022]
    Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

  3. 2. Evaluation of the test procedure for a Rubber Balloon Soil Densitometer

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Mohammad Minhajur Ahmed; [2021]
    Keywords : Rubber Balloon Soil Densitometer; compacted soil; density; volumetric measurement; artificial pits.;

    Abstract : A Rubber Balloon Soil Densitometer is one of the essential apparatuses in Geotechnical Engineering to measure the in-place volume of compacted soil to calculate the soil density. In 2019, some renowned institutions and organizations, Vattenfall, Luleå University of Technology, Uppsala University, Lund University, and HydroResearch AB, were involved in a research project.

  4. 3. Assessment of the water storage potential at Lake Mjölhatteträsk on Storsudret, Gotland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Amanda Uhlin; Isabelle Hajek; [2019]
    Keywords : MIKE SHE; MIKE HYDRO; GIS; groundwater modelling; hydrogeology; hydrologic cycle; water demand; MIKE SHE; MIKE HYDRO; GIS; grundvattenmodellering; hydrogeologi; hydrologiska cykeln; vattenbehov;

    Abstract : During the recent summers, Gotland has suffered from drinking water shortage and due to the climate change, the water shortage can possible increase in the future. To find a solution, the Swedish Environmental Research Institute IVL and Region Gotland are going to build a testbed at Storsudret located on the south of Gotland, to investigate different sustainable solutions.

  5. 4. Aeolian and Pedogenic Processes of Loess in Southern England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ragna Orbe; [2019]
    Keywords : loess; Pegwell Bay; grain size distribution; magnetic susceptibility; past-climate reconstruction; lössavlagringar; Pegwell Bay; partikelstorleks distribution; magnetisk mottaglighet; historisk klimatrekonstruktion;

    Abstract : Loess is an aeolian sediment that can be utilized as a detailed proxy of past climate, since it is one of few sediments that is deposited directly from the atmosphere on land. Investigation of loess deposits can give understanding of past regional and local wind circulation patterns and velocities, atmospheric dustiness, as well as paleo-precipitation and weathering conditions.

  6. 5. Nedbrytning av alkyleteraminer som används vid omvänd katjonsflotation av järnmalm

    University essay from SLU/Department of Molecular Sciences

    Author : Erik Gunnars; [2018]
    Keywords : omvänd flotation; akyleteraminer; nedbrytning; anrikning av järnmalm;

    Abstract : Vetskapen kring vad som händer med kemikalier i naturen är viktigt för att kunna bedöma om användningen av dem kan vara hållbar. Företag måste kunna visa att kemikalier som används i deras industriprocesser uppfyller vissa miljökrav bl.a. enligt ECHA:s riktlinjer. READ MORE
