Estimation of annual runoff by exploiting long-term spatial patterns and short records within a geostatistical framework
Roksvåg, Thea; Steinsland, Ingelin; Engeland, Kolbjørn (Peer reviewed; Journal article, 2020)In this article, we present a Bayesian geostatistical framework that is particularly suitable for interpolation of hydrological data when the available dataset is sparse and includes both long and short records of runoff. ... -
Estimation of Z-R relationship and comparative analysis of precipitation data from colocated rain-gauge, vertical radar and disdrometer
Cyr, Isabel (Master thesis, 2014)The estimation of precipitation rates and accumulations constitutes an essential input data for distributed hydrological models and for many hydrometeorological applications, such as short term hydro-scheduling, forecasting ... -
A geostatistical spatially varying coefficient model for mean annual runoff that incorporates process-based simulations and short records
Roksvåg, Thea; Steinsland, Ingelin; Engeland, Kolbjørn (Peer reviewed; Journal article, 2022)We present a Bayesian geostatistical model for mean annual runoff that incorporates simulations from a process-based hydrological model. The simulations are treated as a covariate and the regression coefficient is modeled ... -
Journal of the Royal Statistical Society: Series C (Applied Statistics) Journal of the Royal Statistical Society: Series C (Applied Statistics) ORIGINAL ARTICLE Open Access A two-field geostatistical model combining point and areal observations—A case study of annual runoff predictions in the Voss area
Roksvåg, Thea; Steinsland, Ingelin; Engeland, Kolbjørn (Peer reviewed; Journal article, 2021)We estimate annual runoff by using a Bayesian geostatistical model for interpolation of hydrological data of different spatial support: streamflow observations from catchments (areal data), and precipitation and evaporation ... -
Pre- and postprocessing flood forecasts using Bayesian model averaging
Hegdahl, Trine Jahr; Engeland, Kolbjørn; Steinsland, Ingelin; Singleton, Andrew (Peer reviewed; Journal article, 2023)In this study, pre- and postprocessing of hydrological ensemble forecasts are evaluated with a special focus on floods for 119 Norwegian catchments. Two years of ECMWF ensemble forecasts of temperature and precipitation ... -
Streamflow forecast sensitivity to air temperature forecast calibration
Hegdahl, Trine Jahr; Engeland, Kolbjørn; Steinsland, Ingelin; Tallaksen, Lena M. (Journal article; Peer reviewed, 2019)In this study, we used meteorological ensemble forecasts as input to hydrological models to quantify the uncertainty in forecasted streamflow, with a particular focus on the effect of temperature forecast calibration on ... -
Water consumption from hydropower plants – review of published estimates and an assessment of the concept
Bakken, Tor Haakon; Killingtveit, Ånund; Engeland, Kolbjørn; Alfredsen, Knut; Harby, Atle (Journal article; Peer reviewed, 2013)Since the report from IPCC on renewable energy (IPCC, 2012) was published; more studies on water consumption from hydropower have become available. The newly published studies do not, however, contribute to a more ... -
