  1. 1. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE

  2. 2. Long-term morphological evolution of Cua Lo inlet, Central Vietnam

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Nikita Tegenfeldt; Orio Johansson; [2020]
    Keywords : Inlet morphology; Sand spit; Water exchange; Numerical modelling; Cua Lo river mouth; Sediment transport; Technology and Engineering;

    Abstract : Cua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. READ MORE

  3. 3. Increased leaching of metals as a result of foundation work

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emmy Mattisson; [2018]
    Keywords : Principal components analysis; Modified double mass analysis; Geochemistry; Sulphide bedrock; Remediation methods; Surface water pollution;

    Abstract : Heavy metal contamination in the environment is a global issue that is likely to increase in the future. This report investigates a construction area in which increased concentrations of the heavy metals cadmium, cobalt, copper, nickel and zinc and a decreased pH-value has been observed in the surface water recipient.

  4. 4. Single-Grain Zircon U-Pb Dating and Magnetic Susceptibility of Polish Loess to Determine Late Quaternary Dust Provenance and Paleoclimate

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Engström Johansson; [2018]
    Keywords : dust provenance; Polish loess; paleoclimate; single-grain zircon U-Pb dating; magnetic susceptibility; härkomstområden för atmosfäriskt stoft; polsk lössjord; paleoklimat; U-Pb datering av zirkoner; magnetisk susceptibilitet;

    Abstract : Windblown mineral dust has accumulated into thick loess layers across the European continent. Loess deposits are valuable paleoclimatic archives as they record climate change on centennial- to glacialinterglacial timescales. READ MORE

  5. 5. Glacial lake flood hazard assessment and modelling : a GIS perspective

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maimoona Zehra Jawaid; [2017]
    Keywords : moraine dammed lake; Himalayas; Bhutan; GIS; hazard assessment; dynamic flood model; glacial lake; Physical Geography; ecosystem analysis; digital elevation model; GEM; Earth and Environmental Sciences;

    Abstract : High mountain regions have experienced decreased glacier stability due to varying climate conditions. As glaciers melt, they are being replaced by glacial lakes of different sizes, some of which are prone to outburst flooding, and have caused catastrophic damage to downstream settlements and infrastructure.
