A cost-effective approach to predict dynamic variation of mesohabitats at the river scale in Norwegian systems
(Journal article; Peer reviewed, 2014)This paper presents a cost-effective approach to predict dynamic variation of mesohabitat classes or hydromorphological units (HMUs) in the context of a peaking scenario. Predicting dynamic mesohabitats has been a challenge ... -
A coupled modeling of design and investment parameters for optimal operation of methane bioreactors: Attainable region concept approach
(Journal article; Peer reviewed, 2020)Current practice to design methane bioreactors does not consider all degrees of freedom simultaneously, which raises question of global optimality. This study presents a model-based design framework, which simultaneously ... -
A dataset of wind-driven rain measurements on a low-rise test building in Norway
(Journal article; Peer reviewed, 2007)Semi-empirical models and especially numerical simulation models based on Computational Fluid Dynamics (CFD) are increasingly being used to calculate wind-driven rain (WDR) on building facades. The development, verification ... -
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 ... -
A First-Principles Study of the Al (001)/Fe(0-11) Interface
