Modelling mitigation measures for smolt migration at dammed river sections
(Journal article; Peer reviewed, 2019)There is no generic solution to establish safe passage of downstream migrating fish passed hydropower facilities and mitigation measures are species‐ and site‐specific. Development of solutions is thus often based on “trial ... -
Modelling of a Combined Infiltration and Detention Solution with Investigation of System Performance
(Master thesis, 2021)Befolkningsvekst og urbanisering i kombinasjon med global oppvarming er drivende faktorer for utviklingen av et nytt tankesett innen overvannshåndtering. De eksisterende konvensjonelle avløpssystemene strekker ikke til i ... -
Modelling of Environmental Constraints for Hydropower Optimization Problems – a Review
(Chapter, 2020)Hydropower plants and reservoirs can have negative impacts on their surrounding ecosystems. To limit such impacts, environmental regulations may be imposed. This paper provides a review of literature on the most commonly ... -
Modelling of environmental flow options for optimal Atlantic salmon, Salmo salar, embryo survival during hydropeaking
(Journal article; Peer reviewed, 2014)Recent findings on the causes of Atlantic salmon embryo mortality during winter in a hydropeaking river suggest that long duration drawdowns during very cold periods are the most likely cause of mortality in the ramping ... -
Modelling of skirted foundations for offshore wind turbines
(Doctoral theses at NTNU;2018:140, Doctoral thesis, 2018)The thesis focuses on the modelling of the response of shallow skirted foundations supporting offshore wind turbines (OWT). OWT-structures need to be optimized in design to reduce the cost of energy from offshore wind ... -
Modelling of soil-structure-interaction for flexible caissons for offshore wind turbines
(Journal article; Peer reviewed, 2018)Published foundation models and procedures for calculation of caisson foundation response typically assume a rigid caisson in deformable soil. However, recent published measurement data from a prototype suction bucket ... -
Modelling of stormwater measures and performance evaluation of underground detention basins
(Bachelor thesis, 2019)Effekten av klimaendringer, hyppigere ekstremnedbør og urbanisering, fører til utfordringer for dagens avløpsnett. For å være bedre forberedt for slike hendelser i fremtiden, har flere norske kommuner utarbeidet retningslinjer ... -
Modelling of the Interaction Between Storm and Foul Sewers in a Joint Model and Assessment of Infiltration and Inflow (I/I) A Case Study at Risvollan, Trondheim
(Master thesis, 2019)En av de største utfordringene ved forvaltning av avløpsnett i Norge er tilsig av fremmedvann. Innlekking og infiltrasjon av fremmedvann har negative konsekvenser for både kapasitet, ytelse, kostnad og pålitelighet til et ... -
Modelling of Undrained Clay Subjected to Cyclic Loading - Semi-Explicit Material Model
(Master thesis, 2016)A material model, based on total stresses, has been developed to represent the undrained cyclic behavior of clay for finite element analyses. The material be- havior is split into an average- and a cyclic part, formulated ... -
Modelling of water allocation and availability in Devoll River Basin, Albania
(Master thesis, 2015)ABSTRACT Albania is experiencing a significant increase in energy demands and insufficient generating capacities. Although Albania has a large potential for hydropower development, only 35% has been utilized so far. The ... -
Modelling Open Ocean Aquaculture Structures Using CFD and a Simulation-Based Screen Force Model
(Peer reviewed; Journal article, 2022)The numerical framework of the open source CFD solver REEF3D is utilised to study the fluid–structure interaction of an open ocean aquaculture system and waves. The presence of the net is considered in the momentum equations ... -

Modelling Runoff from Permeable Surfaces in Urban Areas
(Master thesis, 2018)Climate change and urbanization increases the pressure on combined sewer systems in urban areas resulting in increased combined sewer overflows, degraded water quality in receiving waters, and changing stream flows. Permeable ... -
Modelling Seasonal Stability of Shallow Glacial Till on Steep Rock Slopes in Southeast Norway via Finite Element Analysis - A Case Study
(Master thesis, 2018)One of the most common geohazards in the mountainous regions of Norway are debris slides in shallow glacial till horizons overlying steep valley slopes of various bedrock. The predictions pro-duced by the established ... -
Modelling stranded river ice using LiDAR and drone-based models
(Chapter, 2020)Grounded and other remnants of ice in rivers influence flow and alter instream conditions in the period the ice is left in the river channel. Modelling the flow effects of ice have been difficult in the past due to ... -
Modelling Thawing Slope Stability of Arctic Coast
(Master thesis, 2016)Through a literature study, different aspects of frozen ground, physical properties, mechanical behavior of frozen ground, the relation between permafrost and climate, and erosional processes are described. The mechanical ... -
Modelling the flow around and wake behind net panels using large eddy simulations
(Peer reviewed; Journal article, 2021)The fluid flow through a fixed net panel is investigated using large eddy simulations. Computational meshing strategies suitable for smooth and fabric twines are proposed. Numerical validations are conducted by comparing ... -
Modelling the seasonal variations of soil temperatures in the Arctic coasts
(Peer reviewed; Journal article, 2021)The soil temperature within the Arctic coasts within the continuous permafrost is not widely measured; the temporal and spatial resolutions of the measured temperature observations are relatively high. In this study, we ... -
Modelling weir adjustments in the Lærdal river
(Master thesis, 2023)In the context of regulated river management, weirs have historically been employed to counteract the consequences of reduced water flow resulting from river regulation interventions. The Laerdal River in western Norway, ... -
