Hydraulic efficiency and optimization of pipe culvert inlet edges
(Peer reviewed; Journal article, 2023) -
Hydraulic model suitability for hydrodynamic analysis based on LiDAR data of steep rivers
(Master thesis, 2020)A hydraulic model is an essential tool to estimate water depth, flow velocity, inundation extent, water surface elevation, and other hydraulic parameters. Different hydrodynamic models have been developed, and some of them ... -
Hydraulic modeling of flow ramping related to river morphology and river geometry
(Master thesis, 2021) -
Hydraulic modeling of free surface flow and scour around bridge piers
(Master thesis, 2023)Tidligere kunne kajakkpadlere surfe på en stående bølge under Sluppen bru i Nidelva i Trondheim. Imidlertid avslørte batymetrimålinger at ei erosjonsgrop hadde dannet seg nedstrøms bropilarene. Erosjonsgropa ble fylt igjen, ... -
Hydraulic modeling of the Lærdal river
(Master thesis, 2019)Hydraulic modeling is a useful tool to analyze the impacts from changes in the flow and in the morphology of a river. To achieve accurate results it is necessary to collect detailed data of the topography of the area, ... -
Hydraulic modeling using image-derived bathymetry
(Master thesis, 2022)River batheymetry is crucial for the numerical modeling of floods and other river phenomena. Airborne scanning with LiDAR provides accurate river bathymetry. However, data collection using such an instrument is costly and ... -
Hydraulic Performance of Advanced Treatment Media to Improve Quality of Stormwater from Airports Exposed to De-icing Chemicals
(Master thesis, 2016)Winter-runoff from airports contains a high fraction of contaminated stormwater. Contaminants such as de-icing chemicals propylene glycol and potassium formate, heavy metals and PAHs are often present in stormwater runoff ... -
Hydraulic physical model production with Computer Numerically Controlled (CNC) manufacturing techniques
(Journal article; Peer reviewed, 2018)Physical models are a well-accepted tool in hydraulic engineering, allowing for the detailed characterisation of flow processes and the validation of structure designs with complex boundary conditions. The methods used to ... -
Hydraulic Scale Modeling of Sediments for Pressurized Sand Traps
(Master thesis, 2018)I senere år har flere norske vannkraftverk opplevd driftsproblemer på grunn av sedimenter i turbinvannet. Dette kan føre til redusert virkningsgrad på turbin og dermed økonomiske tap. Et forskningsprosjekt på sandfang har ... -
Hydraulic scale modelling and thermodynamics of mass oscillations in closed surge tanks
(Journal article; Peer reviewed, 2015)The design and results from a hydraulic scale model of mass oscillations in a hydropower plant with a closed surge tank constructed as an underground rock cavern are presented. The results from the model test of an existing ... -
Hydraulic Scale Modelling of Flow Calming Structures for Hydropower Plants
(Master thesis, 2019)Several large hydropower plants in Norway have been upgraded with a higher installed capacity, but unfortunately, this upgrade has also brought with it operational problems because of sediments entering penstock and causing ... -
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 ... -
Hydraulic Structures- At the Heart of 21st Century Global Sustainable Development
(Journal article, 2023)For millennia, societal progress, health and prosperous economic growth has been closely linked to development of water infrastructure. Now in the 21st century, humankind faces some immense challenges including increasing ... -
Hydraulic Transient Impact on Surrounding Rock Mass of Unlined Pressure Tunnels
(Peer reviewed; Journal article, 2023)The frequent pressure pulsations due to hydraulic transients in hydropower plants induce cyclic loading on the rock mass that may contribute to increased instances of block falls and increased risk of tunnel collapse over ... -
Hydraulisk modellering av kraftverksdrift i Tokkeåi
(Master thesis, 2017)En todimensjonal hydraulisk modell har blitt konstruert i HEC-RAS 5.0 for elven Tokkeåi (5 km lang) i Telemark. Hovedformål for oppgaven er å vurdere graden av effektkjøring av kraftverk. Elven deler seg i flere løp, noe ... -
Hydraulisk utforming av nedløp fra gateavrenning
(Master thesis, 2015)I denne masteroppgaven er det sett på hvordan den hydrauliske kapasiteten til forskjellige rister varierer med hensyn på helning, vannføring i vegbanen, ristutforming og størrelse. Det er sett på hvordan kapasiteten beregnes ... -
Hydrodynamic Coupling of Viscous and Non-Viscous Numerical Wave Solutions Within the Open-Source Hydrodynamics Framework REEF3D
(Chapter, 2021)A comprehensive understanding of the marine environment in the offshore area requires phase-resolved wave information. For the far-field wave propagation, computational efficiency is crucial, as large spatial and temporal ... -
