An improved framework for the assessment of water consumption from hydropower production
Bakken, Tor Haakon (Doctoral theses at NTNU;2016:340, Doctoral thesis, 2016)Climate change and the needed reductions in the use of fossil fuels call for the development of renewable energy sources. Hydropower is today the dominant renewable technology in the energy system and in some regions ... -
Are Reservoirs Water Consumers or Water Collectors? Reflections on the Water Footprint Concept Applied on Reservoirs
Bakken, Tor Haakon; Johnsen, Fredrikke; Killingtveit, Ånund; Alfredsen, Knut (Journal article; Peer reviewed, 2015)IPCC Special Report on Renewable Energy Sources (2011) revealed potentially very high water consumption rates from hydropower production compared to other renewable technologies, but suffered from few studies and methodological ... -
Assessing Climate Change Impacts on Global Hydropower
Hamududu, Byman; Killingtveit, Ånund (Journal article; Peer reviewed, 2012)Currently, hydropower accounts for close to 16% of the world’s total power supply and is the world’s most dominant (86%) source of renewable electrical energy. The key resource for hydropower generation is runoff, which ... -
Assessment of the impacts of landscape patterns on water quality in Trondheim rivers and Fjord, Norway
Chang, Tong; Nie, Linmei; Killingtveit, Ånund; Nøst, Terje; Lu, Jinmei (Peer reviewed; Journal article, 2022)Due to the impacts of hydrological and ecological processes on water quality, discharges from upstream catchments have induced significant pollution to the recipients. This study aims to investigate the possible pollution ... -
Climate Change and impact on Water Resources and Hydropower - The case of Vanatori Neamt in the Carpathian region of Romania
Killingtveit, Ånund; Adera, Abebe Girmay (Report, 2017)The project “Intelligene Energy Systems in Protected Areas” was initiated by the Technical University of Iasi (TUIASI) with two Norwegian partners, SINTEF Energy Research and Norwegian University of Science and Technology ... -
Environmental Impacts of Pumped Storage Hydro Power Plants
Patocka, Filip (Master thesis, 2014)Massive development of new renewable energy sources is taking place all over the world in 21st century and Europe is not an exception. Wind turbine parks are being planned and built on shore, in coastal zones and in the ... -
Estimating runoff from ungauged catchments using regional modelling
Lobintceva, Ekaterina (Master thesis, 2014)Establishing runoff series from ungauged catchment is a central challenge in hydrology. In Norway this is particularly evident in the design of small hydropower. The location of the power plant often is in small catchments ... -
Flood-forecasting and flood management for the Skienselva river system in Norway
Killingtveit, Ånund; Alfredsen, Knut; Rinde, Trond; Østhus, Nicolai; Røhr, Paul Christen (Peer reviewed; Journal article, 2021)Hydropower reservoirs can be useful tools for flood management in regulated rivers and can reduce or eliminate dangerous flood events by storing water during flood peaks and releasing it later in a controlled way. The ... -
Hydrological Assessment of Water Resources in Bergen - Climate Change Impacts
Riisnes, Birthe Kvale; Kristvik, Erle (Master thesis, 2015)Bergen Waterworks is reliant on steady loads of precipitation to meet the drink- ing water demand. Accordingly, the system is vulnerable to drought events and seasonal changes in inflow. Climate change impact analysis, as ... -

Hydrological data for small hydropower plants
Karlsson, Irene (Master thesis, 2014)During last years extensive development of small hydropower plants has taken place, and many of that plants are frequently located in small catchments. Mainly there is no runoff data for these small catchments, because ... -
Hydropower Production in Future Climate Scenarios: The Case for Kwanza River, Angola
Hamududu, Byman Hikanyona; Killingtveit, Ånund (Journal article; Peer reviewed, 2016)Climate change is altering hydrological processes with varying degrees in various regions of the world and remains a threat to water resources projects in southern Africa. The likely negative impacts of changes in Africa ... -
Hydropower Production in Future Climate Scenarios; the Case for the Zambezi River
Hamududu, Byman Hikanyona; Killingtveit, Ånund (Journal article; Peer reviewed, 2016)Climate change remains a threat to water resources projects in southern Africa where impacts resulting from changes in climate are projected to be negative and worse than in most other regions of the world. This work ... -
