A parameter parsimonious approach for catchment scale urban hydrology – Which processes are important?
(Journal article, 2020)Increased urbanization and increased observed precipitation intensity and -frequency due to climate change call for urban hydrological models capable of describing urban flow dynamics in data-scarce areas. A parameter ... -

(Report, 2014)Rapporten oppsummerer resultater og erfaringer fra FoU-prosjekt 81072 Pilotstudie: Kartlegging av snøskredterreng med ATES (Avalanche Terrain Exposure Scale). Det er i løpet av prosjektperioden: • Oversatt og testet ATES’ ... -
The potential influence of Atlantic salmon Salmo salar and brown trout Salmo trutta on density and breeding of the white-throated dipper Cinclus cinclus
(Journal article, 2017)Interactions between birds and fish are often overlooked in aquatic ecosystems. We studied the influence of Atlantic salmon and brown trout on the breeding population size and reproductive output of the white-throated ... -
Predicting hourly flows at ungauged small rural catchments using a parsimonious hydrological model
(Journal article, 2019)Streamflow data is important for studies of water resources and flood management, but an inherent problem is that many catchments of interest are ungauged. The lack of data is particularly the case for small catchments, ... -
Present and future changes in winter climate indices relevant for access disruptions in Troms, northern Norway
(Journal article, 2020)A number of seaside communities in Troms, northern Norway, are vulnerable to sudden weather-induced access disruptions due to high-impact weather and dependency on one or few roads. In this paper we study changes in winter ... -
Pumpekraft i Noreg
(Report, 2011)Pumpekraftverk har også lenge vore brukt for å regulere produksjon i høve variasjonar i forbruket, men det er førebels ingen pumpekraftverk i Noreg som er bygd for å regulere på kort sikt. For å styrke kunnskapen om ... -
Quantifying the Ocean, Freshwater and Human Effects on Year-to-Year Variability of One-Sea-Winter Atlantic Salmon Angled in Multiple Norwegian Rivers
(Journal article, 2011)Many Atlantic salmon, Salmo salar, populations are decreasing throughout the species' distributional range probably due to several factors acting in concert. A number of studies have documented the influence of freshwater ... -
Rapid recovery of normal gill morphology and blood physiology in brown trout (Salmo trutta) after short-term exposure to toxic concentrations of aqueous aluminium under non-steady state chemical conditions
(Journal article, 2021)Freshwater acidification is characterised by elevated concentrations of aqueous aluminium. Global emissions of acidifying agents are reduced due to international agreements, and freshwater acidification has shifted from ... -
Reconciling Simulated Moisture Fluxes Resulting from Alternate Hydrologic Model Time Steps and Energy Budget Closure Assumptions
(Journal article, 2006)Hydrological model predictions are sensitive to model forcings, input parameters, and the parameterizations of physical processes. Analyses performed for the Variable Infiltration Capacity model show that the resulting ... -
Rekalibrering av flomvarslingas HBV-modeller med inndata fra seNorge, versjon 2.0
(Report, 2017)Flomvarslingstjenestens HBV-modeller er rekalibrert. Inndata til de rekalibrerte modellene er gjennomsnittlig nedbør og temperatur for hver av 10 høydesoner i nedbørfeltet. Klimadataene leses fra seNorge-griddet, versjon ... -
Reproductive migration of brown trout in a small Norwegian river studied by telemetry
(Journal article, 2004)The movement of 34 large (39–73 cm standard length) brown trout Salmo trutta was monitored using radio telemetry for up to 74 days in Brumunda, a small Norwegian river (mean annual discharge 3·3 m3 s−1) flowing into the ... -
Revegetering av steintipper i fjellet
(Report, 2011)I denne rapporten oppsummerer vi de viktigste resultatene fra prosjektet “Steintipper i fjellet”. I prosjektet har vi i tidsrommet 2008–2010 undersøkt vegetasjonssammensetningen på 19 steintipper og omgivelsene til disse ... -
Risiko- og sårbarhetsanalyse for økt integrasjon av AMS-DMS-SCADA
(NVE Ekstern rapport;2018:15, Report, 2018)Rapporten beskriver risiko og sårbarhet i kraftnettet ved tettere kobling mellom AMS, DMS og SCADA. Sikkerhetsutfordringene ved økt integrasjon er håndterbare, gitt iverksetting av gode forebyggende tiltak -
Samkjøring av vær- og vannføringsdøgnet i hydrologiske modeller
(NVE Rapport;2018:71, Report, 2018)Rapporten presenterer en test der HBV-modellen kjøres med fire ulike kombinasjoner av døgninndelinger av datasettene for vær- og vannføringsdata, og et utvalg kvalitetskriterier sammenliknes. Testen konkluderer med en ... -
Satellite observed SCA and gamma distributed snow in the HBV model
(Research report, 2009)Areas having a seasonal snowpack experience a risk of melt-floods. The magnitude of such a flood is highly dependent on the available water stored in the snow reservoir. Therefore it is of vital importance to estimate the ... -
Sauland kraftverk
(Report, 2010)Utbyggingen av Sauland kraftverk vil føre til at Hjartdøla stort sett vil islegge seg der den i dag går åpen. Mellom kraftverksutløpet og Heddalsvatn vil derimot dagens variable isforhold bli ytterligere svekket slik at ... -
SenDiT: The Sentinel-2 Displacement Toolbox with Application to Glacier Surface Velocities
(Journal article, 2019)Satellite imagery represents a unique opportunity to quantify the spatial and temporal changes of glaciers world-wide. Glacier velocity has been measured from repeat satellite scenes for decades now, yet a range of satellite ... -
seNorge2 daily precipitation, an observational gridded dataset over Norway from 1957 to the present day
(Journal article, 2018)The conventional climate gridded datasets based on observations only are widely used in atmospheric sciences; our focus in this paper is on climate and hydrology. On the Norwegian mainland, seNorge2 provides high-resolution ... -
