  1. 11. Lake sedimentary archives of medieval mining and smelting in Sweden : tracking environmental changes from site to landscape

    Författare :Erik Myrstener; Richard Bindler; Christian Bigler; Elinor Andrén; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; environmental science; miljövetenskap;

    Sammanfattning : While the environmental impact of the industrial age is massive, including climate change, pollution, microplastics and habitat loss, our influence reaches further back than many recognize. In Sweden, an early and important activity with large potential impact was the mining and smelting of iron, copper and silver ores over the last ~800 years. LÄS MER

    Sammanfattning : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. LÄS MER

  4. 13. Studies of the morphological activity of rivers as illustrated by the River Fyris

    Författare :Filip Hjulström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : (Summary)The investigation bears upon a determination of the rate of the mechanical and chemical denudation within the Fyris river-basin north of Uppsala in Central Sweden. The introduction deals with the morphological activity of rivers in general and the different methods (the sampling and the plot methods) for the determination of the rate of degradation. LÄS MER
