  • A practical methodology to perform global sensitivity analysis for 2D hydrodynamic computationally intensive simulations 
    Mirza Alipour, Saba; Engeland, Kolbjørn; Leal, J B (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract Sensitivity analysis is a commonly used technique in hydrological modeling for different purposes, including identifying the influential parameters and ranking them. This paper proposes a simplified ...
  • An event-based approach to explore selected present and future atmospheric river–induced floods in Western Norway 
    Hegdahl, Trine J.; Engeland, Kolbjørn; Müller, Malte; Sillmann, Jana (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The aim of this study is to investigate extreme precipitation events caused by atmospheric rivers and compare their flood impact in a warmer climate to current climate using an event-based storyline approach. The study was ...
  • Changing flood dynamics in Norway since the last millennium and to the end of the 21st century 
    Huo, Ran; Li, Lu; Engeland, Kolbjørn; Xu, Chong-Yu; Chen, Hua; Paasche, Øyvind; Guo, Shenglian (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    With the recent warming trend over Europe and the Arctic, the Nordic regions have experienced more frequent and damaging extreme hydrological events which are anticipated to increase towards the end of the 21st century. ...
  • Flexible and consistent Flood–Duration–Frequency modeling: A Bayesian approach 
    Barna, Danielle Marie; Engeland, Kolbjørn; Thorarinsdottir, Thordis Linda; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Design flood values give estimates of flood magnitude within a given return period and are essential to making adaptive decisions around land use planning, infrastructure design, and disaster mitigation. Many hydrologic ...
  • New flood frequency estimates for the largest river in Norway based on the combination of short and long time series 
    Engeland, Kolbjørn; Aano, Anna; Steffensen, Ida Grøndahl; Støren, Eivind Wilhelm Nagel; Paasche, Øyvind (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract. The Glomma River is the largest in Norway, with a catchment area of 154 450 km2. People living near the shores of this river are frequently exposed to destructive floods that impair local cities and communities. ...
  • Pre- and postprocessing flood forecasts using Bayesian model averaging 
    Hegdahl, Trine Jahr; Engeland, Kolbjørn; Steinsland, Ingelin; Singleton, Andrew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract 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 ...
  • Streamflow forecast sensitivity to air temperature forecast calibration 
    Hegdahl, Trine Jahr; Engeland, Kolbjørn; Steinsland, Ingelin; Tallaksen, Lena M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract. 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 ...
