(Master thesis / Masteroppgave, 2016)The Svalbard archipelago is subject to winter warm events, where daily mean air temperature exceeds 0°C. These warm events occur when low pressure systems direct air northwards across the Nordic Seas towards the west coast ...
-
(Master thesis / Masteroppgave, 2011)A one-dimensional heat flux model has been developed in this study to analyze changes in heat propagation within debris cover on a glacier and the subsequent melt. The model can accept data collected in situ for calculations ...
-
(Master thesis / Hovedoppgave, 1964)
-
(Master thesis / Masteroppgave, 2022)Climate change has impacted the global water cycle and has changed how streamflow behaves in Norway. Knowledge about high and low flows are important to be prepared for future changes, such as changes in water availability ...
-
(Master thesis / Masteroppgave, 2015)The motion of temperate and polythermal glaciers is influenced by the seasonal input of meltwater to the basal hydrological system. Spatial differences in the bed sliding velocities lead to stress and strain in the glacier ...
-
(Master thesis / Masteroppgave, 2013)Recent studies have shown that the duration of seasonal ice cover on lakes and rivers over the Northern Hemisphere has declined over the 19th and 20th Centuries, mainly as a consequence of rising temperatures. However, ...

(Master thesis / Masteroppgave, 2019)
-
(Master thesis / Masteroppgave, 2010)Denne oppgaven har som formål å framheve anomalier som kan indikere begravde arkeologiske objekter. For å gjøre dette har flybårne hyperspektrale data blitt analysert. Testområdet var et område i Odberg i Lågendalen hvor ...
-
(Master thesis / Masteroppgave, 2018)Stable water isotopes have become a key element in hydrological and atmospheric research topics. Hydrologists aim to close the water cycle, and the improvement of measurement techniques and models makes that they come ...
-
(Master thesis / Masteroppgave, 2018)The water cycle and its extremes are heavily affected by human activities, such as reservoirs operations and water abstractions. The aim of this study was to evaluate impacts of human interventions (HI) on the water cycle ...
-
(Master thesis / Masteroppgave, 2010)I denne oppgaven er det gjort interferometriske tidsserieanalyser ved hjelp av permanent spreder-teknikken (PS-teknikken) for Flåm/Aurland og Nord-Island. Denne teknikken benytter seg av SAR-data (Synthetic Aperture Radar) ...
-
(Master thesis / Masteroppgave, 2016)Landslides are amongst the most destructive natural hazards, causing damage to infrastructures, such as roads, railways and houses, and can, in a worst-case scenario, take lives. By studying the effect and response of ...
-
(Master thesis / Masteroppgave, 2021)In Norway, threats of geohazards are high, one of these geohazards that causes great damage every year is the springflood. As the climate is changing, it is expected that there will be significant changes to the trend, ...

(Master thesis / Masteroppgave, 2021)
-
(Master thesis / Masteroppgave, 2015)Denne masteroppgaven er en fortsettelse av et nylig igangsatt overvåkningsprogram av Marthabreen på Svalbard. På grunn av kullutvinning i Svea, særlig den nye gruva i Lunckefjell godkjent i 2011, er det nødvendig å undersøke ...

(Master thesis / Hovedoppgave, 2003)
-
(Master thesis / Masteroppgave, 2013)Temperaturtilhøva i Gråsubreen og Juvfonne, to ismasser i Jotunheimen, har blitt kartlagt. Istemperaturen har blitt målt direkte gjennom innsmelting av termistorkablar. Termistorkablane vart installert i april 2012, og ...
-
(Master thesis / Masteroppgave, 2012)I denne oppgaven er potensialet til L-band differensiell interferometrisk SAR (DInSAR) evaluert med hensyn til å detektere ustabile helninger i områder med vanskelige topografiske og klimatiske forhold. I hvilke områder ...
-
(Master thesis / Masteroppgave, 2016)Debris flows and debris slides/avalanches (weather-induced landslides) represent a significant threat to infrastructures and human habitation in Norway. They are triggered by a combination of high intensity rainfall, ...
