  1. 1. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : June Johansson; [2023]
    Keywords : Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Abstract : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. READ MORE

  3. 2. GIS, tracer test and water balance based hydrological analysis in Tarfala, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Elias Koivisto; [2022]
    Keywords : Tarfala; DEM; Tracer test; Water balance; the Arctic; Climate change; Permafrost; Glacier;

    Abstract : Current climate change poses a threat to the Arctic due to increasing temperatures, which cause the permafrost and glaciers to melt and thaw. This thesis focused on analyzing water balances in Tarfala catchment between 2000 and 2020 and using GIS as a support for tracer test results measured in Tarfala in 2021. READ MORE

  4. 3. Effects of Wildfire Burn on Permafrost Landcover and Catchment Hydrology in Manitoba, Canada

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Andreas Andersson; [2019]
    Keywords : wildfire; permafrost; catchment hydrology;

    Abstract : Permafrost is a strongly controlling factor on Arctic hydrology due to its effect on ground permeability, and thus surface and ground water flow paths. As wildfires are increasing in occurrence and magnitude in permafrost regions, they may alter the hydrological regime via permafrost thaw and degradation that increases ground permeability.

  5. 4. Hydrologic modelling of the Zackenberg river basin : an applied study using the Soil and Water Assessment Tool

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Ahlbäck; [2018]
    Keywords : Greenland; SWAT; High Arctic; Distributed Hydrologic Modelling; GIS; surface Water; Earth and Environmental Sciences;

    Abstract : Since the 1980s, the Arctic has experienced an amplified warming of more than twice the rate of the global-mean, leading to large-scale changes in the Arctic hydrologic system, ultimately having cascading feedbacks on the global climate. However, few of today’s distributed models manage to capture the complex processes in Arctic hydrology, and therefore, the aim of this thesis was to evaluate the usage of the distributed Soil and Water Assessment Tool (SWAT) model, to see whether it could capture the different surface water paths and processes characterizing the Arctic water cycle.

  6. 5. Statistical Modelling of Permafrost Extent in the Circum-Arctic Region

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Patricia Koch; [2018]
    Keywords : permafrost; soil organic carbon; growing degree days; statistical modelling; Earth and Environmental Sciences;

    Abstract : Permafrost regions cover approximately a quarter of the Northern Hemisphere and thawing has been recorded in many different locations. The thawing process is likely to continue given that the Northern Latitudes will experience increased warming, which is known as the Arctic Amplification Factor. READ MORE
