Assessing Stability of Coastal Bluffs Due to Combined Actions of Waves and Changing Ambient Temperatures in the Arctic
(Master thesis, 2017)The Arctic coastal zone is characterized by high erosion rates, which are on average 0,5 m/year but can reach up locally to 25 m/year and therefore endanger coastal infrastructure. Additionally, the global warming takes ... -
Development of methods to combine social network analysis and institutional logics applied to research projects in the urban water sector
(Master thesis, 2018)Nowadays, a paradigm shift in the urban water sector is observable: while hierarchical governance structures were present in the past, many currently relevant challenges are characterized by a higher complexity, requiring ... -
Energy potentiality assessment by mean of intelligent pressure management in the hydraulic network of Trondheim
(Master thesis, 2018)The aim of the thesis was to study the electrical producibility of the trondheim water network after having adequately modeled the losses. PAts (Pump As Turbines) have been considered as an alternative to the classic turbines. -
Evaluation of a new natural coagulant for removal of color by coagulation/ceramic membrane filtration
(Master thesis, 2016)This master thesis is based on experiments on a pilot plant at the department of Hydraulic and Environmental Engineering at NTNU. The master thesis is written for the Norwegian company INRIGO AS. The purpose of this master ... -
Filtralite Mono-Multi Fine as an Alternative to Anthracite/Sand Used in the Molde Process
(Master thesis, 2016)The objective of this Master thesis was to find out if a new filter combination called Filtralite Mono-Multi Fine (FMMF) could be used as an alternative to the conventional media combination anthracite and sand. The FMMF ... -
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 ... -
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 ... -
Hydrological Modelling of the Ilabekken Catchment, and Flood Simulations of Ilabekken using HEC-HMS and HEC-RAS
(Master thesis, 2015)As the global climate is changing, the local climate in Trøndelag is expected to be wetter and more extreme in the future. Flooding and erosion are huge challenges in Norway, leading to severe damages each year which lead ... -
Infiltrasjonssandfang - Dimensjoneringskriterier og kapasitetsmåling
(Master thesis, 2017)Denne masteroppgaven omhandler infiltrasjonsbaserte kumløsninger, og fokuserer på en typisk «standardisert» løsning, IFS-kum (infiltrasjonssandfangskum). Kummen er utviklet av StormAqua i Sandnes. Oppgaven er også et ... -
Kombinert hydrologisk - hydraulisk modell for urbane nedbørsfelt
(Master thesis, 2018)Overvannsflom er et økende problem og økt urbanisering og klimaendringer pekes på som hovedårsaker. Foreløpige analyser antyder at nedbøren vil øke både i mengde og intensitet fremover. Ekstreme nedbørshendelser vil kunne ... -
The Melamchi-project as a Multi-Purpose project; water supply and hydropower development
(Master thesis, 2017)Nepal s largest natural resource is the potential for hydropower (HP) development. The potential for HP could help to solve the poor economic situation in Nepal. The main purpose of this master thesis is to ... -
Modeling Water Distribution Systems - Integration Between SCADA Systems and Hydraulic Network Simulation Models
(Master thesis, 2016)The water distribution system conveys water from the water treatment plant (WTP) to the user. A significant amount of the water is lost in the transit. The International Water Supply Association (IWSA) claims that the ... -
Modelling flood events in the Arno River and the interaction with the infrastructures in the city of Florence using REEF3D
(Master thesis, 2018)The first part of this work provides the numerical model overview including the governing equations, the turbulence model and the discretization methods. The second part describes the geographical position of Florence, its ... -
Numerical simulation of sediment flushing in reservoirs
(Master thesis, 2018)As we saw, sediment can be a major factor in decreasing the lifespan, efficiency and profit of a hydropower plant. Countries and companies have to have countermeasures against the sedimentation, where high yields are ... -
Overtopping of embankment dams from landslide generated waves
(Master thesis, 2017)A landslide entering a reservoir transforms its kinetic energy into an impulse wave. This wave propagates across the basin, runs up the shores and may overtop the dam. The consequences of such event are damages to nature ... -
Performance assessment of the semi-distributed hydrological model HYPE for central Norway
(Master thesis, 2017)Norway s water authorities need a comprehensive tool to generate hydrological infor- mation for all water bodies to implement the European water framework directive. The precipitation-runoff model HYPE was developed by the ... -
Performance of Organic Solvent Nanofiltration Membrane for Purification of Omega-3
(Master thesis, 2017)In this master thesis, the performance of organic solvent nanofiltration membrane for purification of Omega-3 is studied. The aim was to contribute to the improvement of the production process of a Norwegian company producing ... -
