  1. 1. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

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

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  3. 2. Nutrient Retention in Constructed Wetlands

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johanna Kero; [2022]
    Nyckelord :Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

    Sammanfattning : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. LÄS MER

  4. 3. Hydraulic Erosion Simulation on the GPU for 3D terrains

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sebastian Isheden; [2022]
    Nyckelord :Hydraulic Erosion; 3D erosion; CUDA; erosion; simulation; Vatten Erosion; 3D erosion; CUDA; erosion; simulering;

    Sammanfattning : Erosion is the action of various natural processes, such as water flow, wind and gravity, that displaces material from one area to another. Creating physically-based models of these complex phenomena has been a major challenge in creating realistic terrain in video games in a fast way, without having a 3D artist model the terrain by hand.

  5. 4. Drivers of topsoil saturated hydraulic conductivity in three contrasting landscapes in Kenya

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :David Falk; [2021]
    Nyckelord :Infiltrability; mixed effects model; Kenya; land degradation; restoration; trees;

    Sammanfattning : Markförsämring i tropiska regioner kan ha förödande konsekvenser för vattentillgänglighet. Vattenkvalité och kvantitet är oerhört viktiga för lokalbefolkningar och är grundförutsättningar för socioekonomisk utveckling då stora delar av befolkningen i många tropiska länder är direkt beroende av jordbruk och boskapshållning för sin inkomst.

  7. 5. 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.
