(Master thesis / Masteroppgave, 2009)Palsas are peat mounds with a perennially frozen core which are mainly formed due to ice segregation. They are located in bogs in warmer (sporadic and discontinuous) permafrost zones and they are therefore sensitive to ...

(Master thesis / Masteroppgave, 2015)Parsimonious snow modelling for application in hydrological models Calibration free methods for estimating spatial distribution and melt of snow
-
Performance evaluation of regional calibration methods for a distributed hydrologic modelling frameworkRestricted Access (Master thesis / Masteroppgave, 2016)Seasonally snow-covered regions are an important source of water and a crucial component of the yearly water balance for substantial areas of the world. The American River, located in the California Sierra Nevada presents ...
-
(Master thesis / Masteroppgave, 2019)Structure-from-Motion (SfM) is a photogrammetric range image technique used for high-resolution 3D modeling, where the 3D information is obtained from sequences of overlapping 2D optical images captured from different ...

-
(Master thesis / Masteroppgave, 2010)I Dovrefjellregionen, Sør-Norge, er det gjort permafrostundersøkelser knyttet til iskjernemorener og steinbreer. På Dovrefjell er det alpin permafrost fra ca 1450-1550 m.o.h., og alle lokalitetene som er undersøkt ligger ...

-
(Master thesis / Masteroppgave, 2013)I denne oppgaven har LiDAR-data innhentet med flybåren laserskanning (FLS) blitt brukt til geografisk analyse av Storsteinsfjellbreen i Nordland. Oppgaven er spesielt rettet mot anvendelser av LiDAR-data innenfor ...
-
(Master thesis / Masteroppgave, 2017)Structure from motion photogrammetry presents a low-cost and time saving way of generating digital surface models and orthoimages using image matching algorithms. The use of structure from motion poses great potential where ...
-
(Master thesis / Masteroppgave, 2021)Streamflow data from gauged catchments plays an important role for water resources management applications such as water resource planning, flood risk management and assessment of the impact of environmental- and climate ...
-
(Master thesis / Masteroppgave, 2022)I denne oppgaven undersøkes kvaliteten på konvensjonelle infiltrasjonsmålemetoder og mulighetene for bruk av konvolusjonære nevrale nett til å bestemme mettet infiltrasjonsrate. En innledende analyse gjør det tydelig at ...
-
(Doctoral thesis / Doktoravhandling, 1991)The recession curve provides important information about the low flow behaviour of rivers, and tells in a general way about the natural water storages feeding the stream. This work has, however, found a high time variability ...
-
(Master thesis / Masteroppgave, 2017)Old images are a valuable source of information in Geosciences. They provide information on the state of an object or phenomenon at a given time. Datasets of the past are produced according to old data standards optimized ...
-
(Master thesis / Masteroppgave, 2011)Intense floods of short duration are called flash floods. They often occur during intense rainfall in small to moderate sized catchments. The time from the causative event (usually rainfall) to the peak of the runoff can ...
-
(Master thesis / Masteroppgave, 2014)Robuste estimater for vannføring avhenger av pålitelige inndata, som temperatur og nedbør. Målstasjoner ligger ofte spredt, dette gjør at lokal temperatur og nedbør må interpoleres fra omkringliggende målestasjoner. Kunnskap ...
-
(Master thesis / Masteroppgave, 2019)All countries are affected by natural hazards in different ways. The recently launched Synthetic Aperture Radar (SAR) Sentinel-1 A and B twin satellites provides large amounts of high-resolution radar data due to their, ...
-
(Master thesis / Masteroppgave, 2010)Tunsbergdalen er en glasialt erodert dal i indre del av Sogn og Fjordane. Innerst i Tunsbergdalen ligger fastlands-Norges og -Europas lengste utløpsbre, Tunsbergdalsbreen. Denne drenerer deler av platåbreen Jostedalsbreen. ...
-
(Master thesis / Masteroppgave, 2014)Utviklingen av sedimentære miljøer og permafrost i Adventdalen i sen kvartær er rekonstruert ved å bruke kryostratigrafiske og sedimentologiske data fra en 60 meter dyp sedimentkjerne i permafrosten. Resultatene blir satt ...
