  1. 16. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  3. 17. Characterization of Landscape Structures and Precipitation in relation to Flooding events in Pampa Deprimida : A Minor Field Study in Argentina

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

    Author : Linnea Svärd; [2023]
    Keywords : Pampeana hydrology; flood risk mapping; runoff; infiltration; precipitation; SCSCN; remote sensingg; Hydrologi på Pampas; kartläggning av översvämningsrisker; avrinning; infiltration; nederbörd; SCS-CN; fjärranalys; Hidrología de la Pampa Deprimida; cartografía del riesgo de inundaciones; escorrentía; infiltración; precipitación; SCS-CN; sensores remotos;

    Abstract : The purpose of the thesis is to characterize flood events within the agricultural fields of flooding Pampa in Argentina. The characterization divides the flat landscape into flood prone areas and endeavour at linking driving factors to flood response based on past events. READ MORE

  4. 18. Evaluation of AI-method for measuring and characterizing particles on-line in drinking water treatment

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Lovisa Ådén; [2023]
    Keywords : Turbidimeter; Particle meter; rapid filtration;

    Abstract : The municipal association Norrvatten produces drinking water at Görväln WTP for approximately 700,000 residents in 14 member municipalities in the northern Stockholm region. To ensure the drinking water meets quality criteria, the water must be carefully monitored by the WTP. READ MORE

  5. 19. Evaluating the Bluespot model with the August 2021 flood in Gävle, Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Oskar Björklund; [2023]
    Keywords : Bluespot model; Urban Pluvial Flood Model; Fill Spill Merge Model; Gävle Flood 2021.;

    Abstract : Floods are one of the most common types of natural disasters. They annually affect vast amounts of people and cause severe economic losses. While fluvial, coastal, and flash floods are well studied, pluvial floods (rain related) have received modest attention from researchers and decision-makers in comparison. READ MORE

  6. 20. Modelling the risk of rainfall events leading to momentary pollution levels exceeding maximum allowed concentrations - A Swedish case study of urban runoff in the Fyris river

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tove Gannholm Johansson; [2022]
    Keywords : urban runoff; flow; rain event; pollution concentration; EQS; MAC-EQS; dagvatten; flöde; regntillfälle; föroreningskoncentration; MKN; MAC-MKN;

    Abstract : The purpose of this study was (1) to study the proportion (X) of the flow in a watercourse that consists of urban runoff during a rain event and (2) to evaluate the risk that a few chosen pollutants, transported by urban runoff, exceed the maximum allowed concentration in the watercourse according to the environmental quality standards (MAC-EQS). The Fyris river in Uppsala, Sweden, was selected as a case study. READ MORE
