  1. 1. Distribution and transport of microplastics and metals in sewage sludge-amended agricultural soil : a Comparative study between microplastics copper, cadmium, and nickel

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Nora Ottander; [2022]
    Nyckelord :Bioturbation; advective transport; earthworm; Aporrectodea longa;

    Sammanfattning : This thesis investigated the vertical transport of microplastics and metals in agricultural soil after sewage sludge application. Sewage sludge is commonly used in agriculture for adding nutrients and carbon to improve the soil quality. LÄS MER

  3. 2. Nanoplastic transport in soils by advection and bioturbation

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Wiebke Mareile Heinze; [2019]
    Nyckelord :column leaching; attachment efficiency; exposure; mixing rates; modelling;

    Sammanfattning : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. LÄS MER

  4. 3. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Martin Larsson; [2019]
    Nyckelord :soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

    Sammanfattning : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. LÄS MER

  5. 4. Near-Surface Energy Balance on an Alpine Rock Glacier: Murtèl-Corvatsch

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Luisa Pruessner; [2017]
    Nyckelord :rock glaciers; energy balance; SNOWPACK; permafrost;

    Sammanfattning : This project investigates the near surface energy balance on the Murt`el-Corvatsch rock glacier in the Upper Engadine, Swiss Alps, using the 1D physical SNOWPACK model. A correct representation of the near surface energy balance is important to predict the long term evolution of permafrost below rock glaciers. LÄS MER

  7. 5. Advective transport times in the river basin of lake Vombsjön

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Författare :Sarha Rodin Holst; Olivia Svensson; [2016]
    Nyckelord :Lake Vombsjön; advective transport; decentralized sewer systems; contaminant transport; transport times; ArcMap; Earth and Environmental Sciences;

    Sammanfattning : The raw water source lake Vombsjön is situated in the center of southern Scania and provides drinking water by artificial groundwater recharge for approximately 450 000 inhabitants each day. More than 2800 households within the catchment of lake Vombsjön treats their domestic wastewater with a decentralized sewer system. LÄS MER
