Comparative evaluation of performances of different conceptualisations of distributed HBV runoff response routines for prediction of hourly streamflow in boreal mountainous catchments
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut (Journal article; Peer reviewed, 2015)Unidentifiability and equifinality of parameters pose challenges to calibration and prediction by conceptual precipitation-runoff models. Evaluation of prediction performances of parametrical parsimonious and more complex ... -
Evaluation of different parameterizations of the spatial heterogeneity of subsurface storage capacity for hourly runoff simulation in boreal mountainous watershed
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut; Abdella, Yisak Sultan; Kolberg, Sjur (Journal article; Peer reviewed, 2015)Identification of proper parameterizations of spatial heterogeneity is required for precipitation-runoff models. However, relevant studies with a specific aim at hourly runoff simulation in boreal mountainous catchments ... -
Evaluation of Regionalization Methods for Hourly Continuous Streamflow Simulation Using Distributed Models in Boreal Catchments
Hailegeorgis, Teklu Tesfaye; Abdella, Yisak Sultan; Alfredsen, Knut; Kolberg, Sjur (Journal article; Peer reviewed, 2015)Regionalization for prediction in ungauged basins at hourly resolution is important for water resources management (e.g. floods and hydropeaking). In this paper, calibration of 26 catchments (39-3090 km2 ) in mid-Norway ... -
Evaluation of storage–discharge relationships and recession analysis-based distributed hourly runoff simulation in large-scale, mountainous and snow- influenced catchment
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut; Abdella, Yisak Sultan; Kolberg, Sjur (Journal article; Peer reviewed, 2016)Evaluation of a recession-based “top-down” model for distributed hourly runoff simulation in macroscale mountainous catchments is rare in the literature. We evaluated such a model for a 3090 km2 boreal catchment and its ... -
High spatial-temporal resolution and integrated surface and subsurface Precipitation-Runoff modelling for a small stormwater catchment
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut (Journal article; Peer reviewed, 2017)Reliable runoff estimation is important for design of water infrastructure and flood risk management in urban catchments. We developed a spatially distributed Precipitation-Runoff (P-R) model that explicitly represents the ... -
Multi-basin and regional calibration based identification of distributed precipitation–runoff models for hourly runoff simulation: calibration and transfer of full and partial parameters
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut (Journal article; Peer reviewed, 2016)Identification of distributed precipitation–runoff models for hourly runoff simulation based on transfer of full parameters (FP) and partial parameters (PP) are lacking for boreal mid-Norway. We evaluated storage–discharge ... -
Regional flood frequency analysis and prediction in ungauged basins including estimation of major uncertainties for mid-Norway
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut (Journal article; Peer reviewed, 2017)Study region 26 boreal catchments (mid-Norway). Study focus We performed regional flood frequency analysis (RFFA) using the L-moments method and annual maximum series (AMS) of mean daily streamflow observations ... -
Regional Frequency Analysis of Extreme Precipitation with Consideration of Uncertainties to Update IDF Curves for the City of Trondheim
Hailegeorgis, Teklu Tesfaye; Thorolfsson, Sveinn T; Alfredsen, Knut (Journal article; Peer reviewed, 2013)Regional frequency analysis based on the method of L-moments is performed from annual maximum series of extreme precipitation intensity to update Intensity–Duration-Frequency (IDF) curves for the city of Trondheim. The ... -
Regional Statistical and Precipitation–Runoff Modelling for Ecological Applications: Prediction of Hourly Streamflow in Regulated Rivers and Ungauged Basins
Hailegeorgis, Teklu Tesfaye; Alfredsen, Knut (Journal article; Peer reviewed, 2017)Prediction of natural streamflow in regulated rivers for derivation of ecologically relevant streamflow metrics (ERSFMs) and prediction in ungauged basins (PUB) are important in management of water resources. However, ...
