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 ... -

(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 Properties of Improved Culvert Inlets
(Master thesis, 2023)Culverts are valuable hydraulic structures necessary to safely route runoff through roadways or natural barriers. They must be correctly designed to avoid upstream flooding, sediment and debris accumulation or structural ... -
Hydraulic properties of the Excavation damage zone
(Master thesis, 2023)Denne avhandlingen undersøker de hydrauliske egenskapene i sprengningsskadesonen. Arbeidet inkluderer numeriske modelleringer av et nytt tunnelkonsept med tanke på vann og frostsikring som utføres ved Hestnes jernbanetunnel. ... -
Hydraulic resistance, shock wave attenuation and gaseous detonation extinction in granular materials
(Doktoravhandlinger ved NTNU, 1503-8181; 65, Doctoral thesis, 2002)Military and civil installations can be equipped with a granular filter, for example in air inlet systems to protect against blast waves. Granular filters also have a certain potential to replace shock valves and to work ... -
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 Pressurized Sand Traps
(Master thesis, 2024)Vannkraftverk har i flere tiår hatt store utfordringer med sedimenter. Hvis disse sedimentene kommer inn i turbinene via ulike kilder, kan det føre til alvorlige skader på turbinen. Dette kan resultere i redusert kraftproduksjon ... -
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 ... -
Hydraulics and Thermodynamics of Closed Surge Tanks for Hydropower Plants
(Doctoral thesis at NTNU;2016:20, Doctoral thesis, 2016)This work has studied the hydraulic and thermodynamics of closed surge tanks for hydropower plants. Surge tanks are applied in hydropower plants to control and reduce the acceleration forces of the water during change of ... -
