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 snow simulations in SHyFT
Ullibarri Lombraña, Joseba (Master thesis, 2017)Snow is a very important component in the hydrological cycle in Norway and crucial for determining reservoir operation during the spring flood to ensure full reservoir and as little flood spill as possible. The Statkraft ... -
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 ... -
Nedbørfelt som enkle, dynamiske system: Bruk av Kirchner (2009) si responsrutine i ein fordelt hydrologisk modell
Bale, Sigri Scott (Master thesis, 2012)Mange mykje brukte hydrologiske modellar, til dømes HBV- modellen, er fysisk baserte; dei bygger på matematiske likningar som skildrar fysiske prosessar i ulike delar av det hydrologiske krinsløpet. Modellane inneheld ... -
Quantitative Estimation of Precipitation from Radar Measurements: Analysis and Tool Development
Abdella, Yisak Sultan (Doctoral theses at NTNU;2016:51, Doctoral thesis, 2016)Current hydrological modeling efforts in Norway usually involve hourly or daily precipitation data obtained from a network of rain gauges. There is often a mismatch between the gauge network density and the spatial scale ... -
Simulering av urban flom ved bruk av data fra værradar.
Reinemo, Petter (Master thesis, 2012)Urban flom forårsaket av store nedbørsmengder har et omfattende skadepotensiale. Forskning viser at det kan forventes en økt frekvens av tilfeller med store nedbørsmengder i Norge i fremtiden, som øker risikoen for urban ...
