1. 1. 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

3. 2. Valley of connections : Networks and spatiality in the archaeological landscape of the Morello Valley in central Sicily

   University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

   Author : Josefine Tegerdal Hune; [2022]
   Keywords : archaeology; spatial analysis; spatiality; GIS; landscape analysis; spatial network analysis; networks; connections; intervisibility; movement; accessibility;

   Abstract : This thesis uses GIS and spatial analysis to study connections in the archaeological landscape of the Morello Valley, in the Enna province in Sicily (Italy). To identify potential social relations, the idea of social networks is adapted into the spatial network analysis. READ MORE

4. 3. Beavers and environmental flow : the contribution of beaver dams to flood and drought prevention

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Wali Uz Zaman; [2019]
   Keywords : beaver dam; beaver pond; environmental flow; flood; drought; GIS;

   Abstract : Before they were driven to near extinction, beavers populated the smaller rivers in Europe, Asia and North America. They are ecosystem engineers, since their dam building activities have a cascading effect on biogeochemistry, hydrology, ecosystem structure as well as biodiversity of the affected and surrounding area.

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. A Risk Assessment Analysis : The risk of saltwater intrusion into freshwater wells and the effects of a futuresea level rise on the Baltic Sea island of Öland

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Marcus Eriksson; [2017]
   Keywords : Saltwater intrusion; well salinization; sea level rise; groundwater; Öland; risk assessment; GIS-analysis;

   Abstract : Freshwater is essential for a functional society and the human well-being. However, it should not be taken for granted. Freshwater aquifers in coastal are subject to current and future risk of becoming saltwater contaminated – reaching a tipping point. Freshwater security on islands is vulnerable. READ MORE
