26. Utvärdering av höjdosäkerhet i digital terrängmodell framtagen med fotografier infångade med DJI Phantom 4 RTK
Kandidat-uppsats, Högskolan i Gävle/SamhällsbyggnadSammanfattning : Att använda obemannade flygfarkoster, även kallat UAS (unmanned aerial systems), i karterings- och modelleringssyften har blivit en välanvänd metod de senaste åren. Mycket på grund av den tekniska utvecklingen som till stor del automatiserat processen med att framställa höjdmodeller och ortofoton. LÄS MER
27. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. LÄS MER
28. Översvämningsanpassade samhällen med grön infrastruktur – ett behov i framtiden? En förändringsanalys av grönytor och översvämningsrisk i Källby, Lund
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The consequences of climate change affect our environment as well as humanity all over the world. For the city of Lund in southern Sweden, climate change consequences are seen as an increase of both intensity and frequency of extreme rain events, which causes an extensive risk for pluvial flooding.

29. Urban Growth and Environmental Risks - A GIS-Based Analysis of Landslide Susceptibility in Bukavu (Democratic Republic of the Congo)
Magister-uppsats, Umeå universitet/Institutionen för geografiSammanfattning : The city of Bukavu, located at the eastern border of the Democratic Republic of Congo in the province of South Kivu, is a large and densely populated urban agglomeration that has experienced rapid growth during recent years. At the same time, Bukavu has been repeatedly struck by environmental hazards, especially by devastating landslides. LÄS MER
30. High resolution modelling and analysis of urban flooding
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : The predictions on climate change and precipitation patterns in the near future, as well as urbanization, lead to higher volumes of runoff, which in turn challenge the sustainability and functionality of urban drainage pipe networks. In order to understand how these changes will affect the existing infrastructure in urban areas, integrated urban water model software are needed to identify effective solutions to minimize urban flooding.
