Assessment of solar energy resources in Ethiopia : modeling solar radiation and GIS-based multi-criteria analysis
Tekle, Fikremariam Teshome (Master thesis, 2014)The sun is an ultimate source of energy for life on earth, and hence the knowledge of solar radiation is essential for hydrological, climatological, biological modeling and utilization of renewable energy resources. Solar ... -
Correspondence: Reply to ‘Challenges with dating weathering products to unravel ancient landscapes’
Fredin, Ola; Viola, Giulio; Zwingmann, Horst; Sørlie, Ronald; Brönner, Marco; Lie, Jan-Erik; Grandal, Else Margrethe; Müller, Axel; Margreth, Annina; Vogt, Christoph; Knies, Jochen (Journal article; Peer reviewed, 2017) -
Deconvoluting complex structural histories archived in brittle fault zones
Viola, Giulio; Scheiber, Thomas; Fredin, Ola; Zwingmann, Horst; Margreth, A; Knies, Jochen (Journal article; Peer reviewed, 2016)Brittle deformation can saturate the Earth’s crust with faults and fractures in an apparently chaotic fashion. The details of brittle deformational histories and implications on, for example, seismotectonics and landscape, ... -
Deglaciation of Fennoscandia
Stroeven, Arjen P.; Hattestrand, Clas; Kleman, Johan; Heyman, Jakob; Fabel, Derek; Fredin, Ola; Goodfellow, Bradley W.; Harbor, Jonathan M.; Jansen, John D.; Olsen, Lars; Caffee, Marc; Fink, David; Lundqvist, Jan; Rosqvist, Gunhild C.; Strömberg, Bo; Jansson, Krister N. (Journal article; Peer reviewed, 2015)To provide a new reconstruction of the deglaciation of the Fennoscandian Ice Sheet, in the form of calendar-year time-slices, which are particularly useful for ice sheet modelling, we have compiled and synthesized published ... -
Lateglacial retreat chronology of the Scandinavian Ice Sheet in Finnmark, northern Norway, reconstructed from surface exposure dating of major end moraines
Romundset, Anders; Akçar, Naki; Fredin, Ola; Tikhomirov, Dmitry; Reber, Regina; Vockenhuber, Christof; Christl, Marcus; Schlüchter, Christian (Journal article; Peer reviewed, 2017)We report results from a comprehensive surface exposure dating campaign in eastern Finnmark, located in the northernmost part of Norway and close to the Norwegian-Russian border. This is a palaeoglaciologically important ... -
Liquefaction of freshwater carbonates led to the February 10, 2011, landslide at the Cöllolar coalfield, eastern Turkey
Akcar, Naki; Yavuz, Vural; Ivy-Ochs, Susan; Fredin, Ola; Nyffenegger, Franziska; Korkut, Mehmet; Margreth, Annina; Anders, Samstad Gylland; Schlunegger, Fritz (Peer reviewed; Journal article, 2019)In February 2011, two landslides in which 11 people were killed, occurred in the Çöllolar open pit mine, situated in the Elbistan Basin in eastern Turkey. In the coalfield, a thick sequence of clay (>100 m) overlies karstic ... -
Manual extraction of bedrock lineaments from high-resolution LiDAR data: methodological bias and human perception
Scheiber, Thomas; Fredin, Ola; Viola, Giulio; Jarna, Alexandra; Gasser, Deta; Lapinska-Viola, Renata (Journal article; Peer reviewed, 2015)Manual extraction of topographic features from Light Detection and Ranging (LiDAR) images is a quick, cost effective and powerful tool to produce lineament maps of fractured basement areas. This commonly used technique, ... -
Modellering av flomveier på Lillehammer, en GIS studie av åpne og blokkerte dreneringsveger i skadepunkter fra flommen juli 2014
Sellæg, Sindre Aal (Master thesis, 2016)Flom knyttet til overflatevann, er allerede en stor utfordring i mange av Norges kommuner. Med fremtidige klimaprognoser med høyere temperaturer og mer intens nedbør, er det ventet flere og kraftigere flommer, og med det ... -

Subglacial landscapes of East Antarctica
Solheim, Marianne (Master thesis, 2019)Kunnskap om erosjonshistorien til den øst-antarktiske innlandsisen er nødvendig for å rekonstruere preglasiale landskap i Antarktis, som i sin tur kan bidra til forståelsen av fortidige og framtidige volumendringer hos ... -
The inheritance of a Mesozoic landscape in western Scandinavia
Fredin, Ola; Viola, Giulio; Zwingmann, Horst; Sørlie, Ronald; Brönner, Marco; Lie, Jan-Erik; Grandal, Else Margrethe; Müller, Axel Bernd; Margreth, Annina; Vogt, Christoph; Knies, Jochen (Journal article; Peer reviewed, 2017)In-situ weathered bedrock, saprolite, is locally found in Scandinavia, where it is commonly thought to represent pre-Pleistocene weathering possibly associated with landscape formation. The age of weathering, however, ... -
Unraveling Scandinavian geomorphology: the LiDAR revolution
Johnson, Mark D.; Fredin, Ola; Ojala, Antti E.K.; Peterson, Gustaf (Journal article; Peer reviewed, 2015)In the observational sciences, technical advances are often followed by dramatic increases in scientific discoveries and improved theory. Leuwenhoek’s microscope and Galileo’s telescope gave us a “better look” at the ... -
Wind farm site selection assessment in the Greater Accra, Volta and eastern regions of Ghana : a GIS spatial multi-criteria assessment
Kabu, Isaiah Kabutey (Master thesis, 2016)Global temperatures have increased since preindustrial times and will continue to do so unless practical measures are taken to halt the emission of carbon and other ozone depleting substances. Wind energy alone has the ...
