  1. 1. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management

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

    Author : Anna Engman; [2022]
    Keywords : peatland; peat volume change; ecohydrology; specific storage; peatland age; torvmark; myr; torvvolymförändring; ekohydrologi; specifik magasinkoefficient; ålder;

    Abstract : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. READ MORE

  2. 2. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lotte Wendt; [2021]
    Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

  3. 3. The Effects of Erosion-control Structures and Gully Erosion on Groundwater Dynamics Along the Kromrivier, Eastern Cape, South Africa

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Vincent de Haan; [2016]
    Keywords : Gully erosion; wetland; groundwater dynamics; erosion-control structures;

    Abstract : The Palmiet wetlands located along the Kromrivier in the Eastern Cape province of South Africa have experienced severe degradation through gully erosion during the past decennia which has been threatening the water quality and water security of large towns in the Nelson Mandela Metropolitan hub. Water scarcity is a growing problem in this region as a result of land degradation and growing erratic rainfall patterns. READ MORE

  4. 4. Carbon loss after forest drainage of three peatlands in southern Sweden

    University essay from SLU/Dept. of Forest Soils

    Author : Maria Gustafsson; [2001]
    Keywords : torv; mosse; kol; dekompostering; dränering; grundvattennivå; pH; CN ratio; avskogning;

    Abstract : Increased amounts of carbon dioxide in the atmosphere influence the global climate. It is therefore important to understand the effects of forestry measures on the distribution of carbon between soil, plants and atmosphere. In the present study, net changes in the peat carbon stores of mires, as a result of forestry drainage, were investigated. READ MORE
