  1. 1. Land-Sea Interactions in the Coastal-Marine System of the Baltic Sea under Hydro-Climatic Variability

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Yuanying Chen; Vladimir Cvetkovic; Carmen Prieto; Marco Marani; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; nutrient loads; hydro-climatic variability; hydrodynamics; solute transport; water quality.; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : This thesis investigates a few important component processes for understanding and quantifying eutrophication in the Baltic Sea, that include characterization of nutrient loadings from land, water flow in the sea under changing climate conditions and transport of solutes originating from different locations along the coast. Furthermore, this study aims to improve our understanding on how processes from land (the nutrient loading conditions) and the sea (transport dynamics and water quality) couple to determine the fate of nutrients in the sea and the water quality in a selected localized coastal area, the Himmerfjärden Bay.

  2. 2. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

  3. 3. Water in roads: Flow paths and pollutant spread

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hedi Rasul; B. Olofsson; Helen Kristine French; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; De-icing salt; Road; Tracer test; ERT; Water content; Road pollutants; Flow pathways; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. READ MORE

  4. 4. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

  5. 5. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Grace Kizito Bakyayita; Ann-Catrine Norrström; Robinah N. Kulabako; Maimuna Nalubega; Roger Thunvik; Ann-Margret Hvitt Strömvall; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biosorbents; cadmium; competitive uptake; Freundlich; pseudo-second-order kinetics; Langmuir; lead; remediation; risks; speciation; toxicity effects; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.
