      Skaugen, Thomas; Lawrence, Deborah; Ortega, Rengifo Zenon (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 ...

    • The potential influence of Atlantic salmon Salmo salar and brown trout Salmo trutta on density and breeding of the white-throated dipper Cinclus cinclus 

      Nilsson, Anna L. K.; L’Abée-Lund, Jan Henning; Vøllestad, Leif Asbjørn; Jerstad, Kurt; Larsen, Bjørn Mejdell; Røstad, Ole Wiggo; Saltveit, Svein Jakob; Skaugen, Thomas; Stenseth, Nils Chr.; Walseng, Bjørn (Journal article, 2017)

    • Predicting hourly flows at ungauged small rural catchments using a parsimonious hydrological model 

      Tsegaw, Aynalem T.; Alfredsen, Knut; Skaugen, Thomas; Muthanna, Tone M. (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, ...

    • Reconciling Simulated Moisture Fluxes Resulting from Alternate Hydrologic Model Time Steps and Energy Budget Closure Assumptions 

      Haddeland, Ingjerd; Lettenmaier, Dennis P.; Skaugen, Thomas (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 ...

    • Satellite observed SCA and gamma distributed snow in the HBV model 

      Skaugen, Thomas; Randen, Frode (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 ...

    • seNorge2 daily precipitation, an observational gridded dataset over Norway from 1957 to the present day 

      Lussana, Cristian; Saloranta, Tuomo; Skaugen, Thomas; Magnusson, Jan; Tveito, Ole Einar; Andersen, Jess (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 

      Skaugen, Thomas; Andersen, Jess (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 ...

    • Snow simulation and forecasting through all Norway: the SeNorge model 

      Endrizzi, Stefano; Skaugen, Thomas (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”), ...

    • A spatial disaggregating procedure for precipitation 

      Skaugen, Thomas (Journal article, 2002)
      A disaggregation procedure is presented to render forecast values of precipitation from an atmospheric model with spatial resolution of 11 × 11 km suitable as input for a distributed hydrological model with spatial resolution ...

    • A stochastic event-based approach for flood estimation in catchments with mixed rainfall/snowmelt flood regimes 

      Valeriya, Filipova; Lawrence, Deborah; Skaugen, Thomas (Journal article, 2019)
      The estimation of extreme floods is associated with high uncertainty, in part due to the limited length of streamflow records. Traditionally, flood frequency analysis or event-based model using a single design storm have ...

    • SURF- urbanhydrologi i fokus 

      Skaugen, Thomas; Lawrence, Deborah; Fleig, Anne; Borsányi, Péter; Ortega, Rengifo Z.; Dyrrdal, Anita V. (Journal article, 2018)
      I løpet av 2018-2020 vil forskere ved NVE, MET og Oslo VAV arbeide med å forstå og modellere urbanhydrologi. Overvannsproblemer i byer og tettbygde strøk er kommet for å bli, og kommuner og sentrale institusjoner innen ...

    • Temporal disaggregation of daily temperature and precipitation grid data for Norway 

      Skaugen, Thomas; Vormoor, Klaus (Journal article, 2013)
      This paper presents a simple approach for the temporal disaggregation from daily to 3-hourly observed gridded temperature and precipitation (1 × 1 km2) on the national scale. The intended use of the disaggregated 3-hourly ...
