A Stochastic Modelling Technique for a Multi-Component Stormwater Management Facility
Rugland, Lise Berit (Bachelor thesis, 2019)Formålet med denne oppgaven er å teste applikasjonen av en hendelses-basert stokastisk modell for et fler-komponent overvannshåndterings system i Sørvest-Norge. Området har både infiltrasjonsflater og konvensjonelle ... -
An analysis of the potential impact of climate change on the structural reliability of drinking water pipes in cold climate regions
Bruaset, Stian; Sægrov, Sveinung (Journal article; Peer reviewed, 2018)The climate is changing worldwide. For the northern hemisphere there are distinct challenges related to climate change. It is expected that temperature on a general basis will increase within the next 100 years, and that ... -
An Approach to planning Data Collection for IAM in VMW: D1-2012-27
Rokstad, Marius Møller (Master thesis, 2012)Ageing infrastructure and changing external conditions has invoked the need for performing proactive and predictive asset management (AM) in water utilities through the utilisation of AM tools. AM tools can act as decision ... -
Application of Infrastructure Asset Management in Enhancing the Performance of Sewer Networks: Assessment of Infiltration and Inflow of Extraneous Water
Beheshti, Maryam (Doctoral theses at NTNU;2019:129, Doctoral thesis, 2019)Wastewater transportation systems are one of the main city lifelines and initial prerequisites for urban areas all over the world. Sewer networks represent a high value in water infrastructure assets, and it is important ... -
Assessing the hydraulic performance of a combined sewer system under climate change using temporal downscaling
Munkerud, Malene Yttersian (Master thesis, 2018)In recent years, climate change has lead to an increasing number of high intensity rain events causing flooding in urban areas around the world. Studies of different future climate scenarios indicate that this increase ... -
Assessment and Control of Methods for Flow Measurement Systems - Master of Civil and Environmental Engineering
Nordvåg, Pauli Petter (Master thesis, 2017)This Master thesis is about the Palmer-Bowlus flume measuring open channel flow rates of waste water at Risvollan. The Department of Civil and Environmental Engineering at the University of Science and Technology (NTNU) ... -
Avrenningsmodell fra urbane felter til Stangelandsåna i Sandnes
Børtveit, Håkon; Petersen, Sigmund Wiig (Master thesis, 2017)For å imøtekomme en framtid med mer nedbør og intense regnbyger, høyere avrenningstopper og andre utfordringer knyttet til overvann, er det planlagt å bygge en ny kulvert under Sandnes sentrum. Denne skal erstatte den ... -
Bærekraftige strategier for rehabilitering av vann- og avløpsnettet
Rygg, Håkon (Master thesis, 2017)Planlegging av utskiftningsmetoder for vann og avløp bør utføres i et langt tidstidsperspektiv. Enkelte effekter kommer ikke fram i et kort tidsperspektiv, men inkluderes derimot i et langt et. Planlegging av denne ... -
Classification of wastewater manholes, procedures and opportunities by applying machine learning
Malvik, Sigurd (Master thesis, 2018)Wastewater manholes are not subject to proper condition assessments in the same manner as pipes. Although manholes have a significant impact on the performance of the wastewater system, no official procedures for how to ... -
Climate change impact on wastewater networks
Wilk, Alicja Helena (Master thesis, 2016)The main findings of this thesis are summarized below : The extrapolations from precipitation analysis are too large for long term planning to be use in design drainage system. The 10 years periods of time are too short ... -

Detection of extraneous water ingress into the sewer system using tandem methods- A case study in Trondheim city
Beheshti, Maryam; Sægrov, Sveinung (Journal article; Peer reviewed, 2019)Infiltration and inflow (I/I) of extraneous water in separate sewer systems are serious concerns in urban water management for their environmental, social and economic consequences. Effective reduction of I/I requires ... -
Deteksjon av fremmedvann i separatsystemer med isotoper
Solberg, Lars (Master thesis, 2017)Utgangspunktet for denne oppgaven er å definere egnetheten til en hittil lite utprøvd metode for lekkasjesøking i separate spillvannsledninger. Rent praktisk tar metoden utgangspunkt i å benytte stabile isotoper i ulike ... -
Drinking Water Safety in African Countries
Hylin, Frida Douglass (Master thesis, 2012)The following report is the result of a literature study of published documents presenting the current water supply situation in Sub-Saharan Africa, in combination with a field trip to the Mpagne village in Cameroon. The ... -
Dynamic metabolism modeling as a decision-support tool for urban water utilities applied to the upstream of the water system in Oslo, Norway
Govindarajan, Venkatesh; Ugarelli, Rita Maria; Sægrov, Sveinung; Brattebø, Helge (Journal article; Peer reviewed, 2014)The paper presents, first, the ‘Dynamic Metabolism Model’ (DMM), developed by the authors, followed by an application to the city of Oslo, capital city of Norway. The time period considered for the analysis is 2013-2043. ... -
Effekt av lokal overvannshåndtering i Sandnes sentrum: Resultater fra modellstudier med programmet STORM
Hamnes, Karoline (Master thesis, 2013)Eksisterende ledningsnett for overvann i nedre del av Sandnes sentrum er allerede overbelastet. Fortetting og klimaendringer forårsaker økt avrenningsintensitet, som sannsynligvis vil medføre oversvømmelser. Avrenningen ... -
