Spatial and Temporal Variation in the Grilse Proportion of Atlantic Salmon in Norwegian Rivers
(Journal article, 2004)Variation in the sea age at maturity of Atlantic salmon Salmo salar was studied in 158 Norwegian rivers over large spatial (58–71°N; 5–30°E) and temporal (1983–2000) scales. Age at sexual maturity was expressed as the ... -
Glaciological investigations in Norway in 2003
(NVE Report;2004:4, Report, 2004)Results of glaciological investigations performed at Norwegian glaciers in 2003 are presented in this report. The main part concerns mass balance investigations. Results from investigations of glacier monitoring are discussed ... -
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 ... -
Long‐term variation in the population structure of Arctic charr, Salvelinus alpinus, and brown trout, Salmo trutta
(Journal article, 2004)The effects of induced water level fluctuations and introduction of the mysid Mysis relicta Lovén on population structure of brown trout, Salmo trutta L., and Arctic charr, Salvelinus alpinus (L.), were studied during ... -
Time variant snow distribution for use in hydrological models
(Journal article, 2004)A model is put forward which focuses on the dynamical evolution of the spatial distribution of snow water equivalent (SWE). We make use of the fact that when the accumulation and ablation process of the snow reservoir is ... -
Glaciological investigations in Norway in 2004
(NVE Report;2005:2, Report, 2005)Results of glaciological investigations performed at Norwegian glaciers in 2004 are presented in this report. The main part concerns mass balance investigations. Results from investigations of glacier monitoring are discussed ... -
Hydrologic effects of land and water management in North America and Asia: 1700–1992
(Journal article, 2006)The hydrologic effects of land use changes, dams, and irrigation in North America and Asia over the past 300 years are studied using a macroscale hydrologic model. The simulation results indicate that the expansion of ... -
Glaciological investigations in Norway in 2005
(NVE Report;, Report, 2006)Results of glaciological investigations performed at Norwegian glaciers in 2005 are presented in this report. The main part concerns mass balance investigations. Results from investigations of glacier monitoring are discussed ... -
Anthropogenic impacts on continental surface water fluxes
(Journal article, 2006)Impacts of reservoirs and irrigation water withdrawals on continental surface water fluxes are studied within the framework of the Variable Infiltration Capacity (VIC) model for a part of North America, and for Asia. A ... -
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 ... -
Disentangling local from macroenvironmental effects: Quantifying the effect of human encroachments based on historical river catches of anadromous salmonids
(Journal article, 2006)In this paper, we use dynamic factor and intervention analysis to identify and quantify the effect of human encroachments on anadromous salmonid catches in 22 Norwegian rivers over a 128-year period. In particular, we ... -
Effects of irrigation on the water and energy balances of the Colorado and Mekong river basins
(Journal article, 2006)An irrigation scheme, based on simulated soil moisture deficit, has been included in the variable infiltration capacity macroscale hydrologic model. Water withdrawals are taken from the nearest river, or, in periods of ... -

Metoder for å måle vannføring i umålte felt
(Journal article, 2007)Forvaltning og utnyttelse av vannressursene stiller i dag høye krav til robusthet og pålitelighet når det gjelder metoder for beregning av vannføring i umålte felt. Temaet har internasjonalt fokus, og IAHS har tatt initiativet ... -
Modelling the spatial variability of snow water equivalent at the catchment scale
(Journal article, 2007)The spatial distribution of snow water equivalent (SWE) is modelled as a two parameter gamma distribution. The parameters of the distribution are dynamical in that they are functions of the number of accumulation and melting ... -

Trends in annual maximum snow water equivalent in Norway (1914-2008)
(Report, 2009)In this report, the large number of annual snow data measured annually by the power production companies and reported to NVE, is analysed for the detection of possible temporal trends. There are no indications of significant ... -

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”), ...
