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 ... -
Simulated precipitation fields with variance-consistent interpolation
(Journal article, 2011)Gridded meteorological data are available for all of Norway as time series dating from 1961. A new way of interpolating precipitation in space from observed values is proposed. Based on the criteria that interpolated ... -
Simulations of snow depth in Norway in a projected future climate (2071-2100)
(Report, 2018)Results for the projected future average snow depth are presented for the 19 counties of Norway at different elevations and at the time of four different popular holiday seasons during the winter and spring. The results ... -
Skred i magasin - overtopping av fyllingsdam fra skredgenererte bølger i magasin
(Report, 2018)Målet med FOU-prosjektet har vært å få mer kunnskap om bølgeoppskylling fra skred i magasin for fyllingsdammer, deriblant å utvikle en konkret metode for å beregne hvilke konsekvenser en overskylling har på fyllingsdammers ... -
Skurdevikåi tilsigsfelt (015.NDZ)
(Report, 2010)Rapporten inneholder en oversikt over målingene som er innsamlet i NVEs database, samt en kort oversikt over historikk og stasjonsbeskrivelse. I denne rapporten gis en analyse av tilstandsoversikt for det hydrologiske året ... -
Snow simulation and forecasting through all Norway: the SeNorge model
(Research report, 2009)A model has been recently set up (since 2006) that provides the snow conditions, along with other hydrometeorological parameters, for all Norway at 1 km resolution. This model is called “Senorge” (meaning “See Norway”), ... -
Spatial and temporal variation in Arctic freshwater chemistry—Reflecting climate‐induced landscape alterations and a changing template for biodiversity
(Journal article, 2020-11)Freshwater chemistry across the circumpolar region was characterised using a pan‐Arctic data set from 1,032 lake and 482 river stations. Temporal trends were estimated for Early (1970–1985), Middle (1986–2000), and Late ... -
Spatial and Temporal Variation in the Grilse Proportion of Atlantic Salmon in Norwegian Rivers
