A dynamic river network method for the prediction of floods using a parsimonious rainfall-runoff model
(Journal article; Peer reviewed, 2019)Floods are one of the major climate-related hazards and cause causalities and substantial damage. Accurate and timely flood forecasting and design flood estimation are important to protect lives and property. The Distance ... -
Applicability of urban streets as temporary open floodways
(Journal article; Peer reviewed, 2020)Climate change coupled with urbanization and its increasing impervious surfaces have caused major challenges for the water sector worldwide. In Norway, an ageing infrastructure with already insufficient drainage capacities ... -
Assessing the effects of four SUDS scenarios on combined sewer overflows in Oslo, Norway: evaluating the low-impact development module of the mike urban model
(Peer reviewed; Journal article, 2020)Paved surfaces, increased precipitation intensities in addition to limited capacity in the sewer systems, cause a higher risk of combined sewer overflows (CSOs). Sustainable drainage systems (SUDS) offer an alternative ... -
Can model-based data products replace gauge data as input to the hydrological model?
(Journal article; Peer reviewed, 2020)Hydrological models require accurate and representative meteorological inputs for better prediction of discharge and hence, the efficient management of water resources. Numerical weather prediction model-based reanalysis ... -
Comparative evaluation of performances of different conceptualisations of distributed HBV runoff response routines for prediction of hourly streamflow in boreal mountainous catchments
(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 ... -
Effect of water level regulation on gradients and levee deposits in the Lake Øyeren delta, Norway
(Journal article; Peer reviewed, 2013)Water level changes resulting from a hydropower regulation have influenced water flow, gradients and sediment processes in the Lake Øyeren delta for about 150 years. They are reflected in the morphology of the islands on ... -
Evaluating three commonly used infiltration methods for permeable surfaces in urban areas using the SWMM and STORM
(Peer reviewed; Journal article, 2021)Climate change and urbanization increase the pressure on combined sewer systems in urban areas resulting in elevated combined sewer overflows, degraded water quality in receiving waters, and changing stream flows. Permeable ... -
How extreme can unit discharge become in steep Norwegian catchments?
(Peer reviewed; Journal article, 2020)This study presents results of observations and analysis of the flood event in Utvik on 24 July 2017. Observations during and after the event, hydraulic simulations and hydrological modelling along with meteorological ... -
Hydraulic scale modelling of the rating curve for a gauging station with challenging geometry
(Peer reviewed; Journal article, 2019)Direct discharge measurements during flood events can be challenging from a technical as well as from a safety point of view. Therefore, flood discharges are often estimated by extrapolating a rating curve. Extrapolations ... -
Limitations in using runoff coefficients for green and gray roof design
(Peer reviewed; Journal article, 2020)Climate change combined with urbanization increases the performance demand on urban drainage systems. Green roofs are one of the most used green infrastructure measures to alleviate the pressure on the urban drainage system ... -
Multi-basin and regional calibration based identification of distributed precipitation–runoff models for hourly runoff simulation: calibration and transfer of full and partial parameters
(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 ... -
Nordic hydrological frontier in the 21st century
(Peer reviewed; Journal article, 2022)The 21st century has brought new challenges and opportunities and has also increased demands on the Nordic hydrological community. Our hydrological science focus and approaches need rethinking and adaptation to the changing ... -
Risk assessment for areas prone to flooding and subsidence: A case study from Bergen, Western Norway
(Peer reviewed; Journal article, 2020)Bergen city centre is prone to both subsidence and flooding. With a predicted increase in precipitation due to climate change, a higher proportion of rainfall becomes surface runoff, which results in increased peak flood ...
