Performance of A Two-Dimensional Hydraulic Model for the Evaluation of Stranding Areas and Characterization of Rapid Fluctuations in Hydropeaking Rivers
(Journal article; Peer reviewed, 2019)Extreme, short-duration fluctuations caused by hydropeaking occurs when hydropower is regulated to cover demand peaks in the electricity market. Such rapid dewatering processes may have a high impact on the downstream ... -
Physical model study on discharge over a dam due to landslide generatedwaves
(Peer reviewed; Journal article, 2020)Impulse waves generated by landslides falling into reservoirs may lead to overtopping of a dam and, in turn, to flooding of the downstream area. In the case of an embankment dam, the overtopping may lead to erosion of the ... -
Pilot Scale Testing of Adsorbent Amended Filters under High Hydraulic Loads for Highway Runoff in Cold Climates
(Journal article; Peer reviewed, 2017)This paper presents an estimation of the service life of three filters composed of sand and three alternative adsorbents for stormwater treatment according to Norwegian water quality standards for receiving surface waters. ... -
Placed Riprap Deformation Related to Axial Load at Toe Support: Physical Modelling
(Peer reviewed; Journal article, 2022)Rockfill dams are hydraulic structures of major importance. They can be exposed to extreme flood events, in turn leading to overtopping. These phenomena erode and affect structural and geotechnical integrity, which in turn ... -
Potential of Biofilters for Treatment of De-Icing Chemicals
(Journal article; Peer reviewed, 2018)Organic de-icing chemicals, such as propylene glycol and potassium formate, cause environmental degradation in receiving water if left untreated, due to the high organic load resulting in oxygen depletion. Biofilters are ... -
Predicting Discharges in Sewer Pipes Using an Integrated Long Short-Term Memory and Entropy A-TOPSIS Modeling Framework
(Peer reviewed; Journal article, 2022)Predicting discharges in sewage systems play an essential role in reducing sewer overflows and impacts on the environment and public health. Choosing a suitable model to predict discharges in these systems is essential to ... -
Quantification Assessment of Extraneous Water Infiltration and Inflow by Analysis of the Thermal Behavior of the Sewer Network
(Journal article; Peer reviewed, 2018)Infiltration and inflow (I/I) of unwanted water in separate urban sewer networks are critical issues for sustainable urban water management. Accurate quantification of unwanted water I/I from individual sources into a sewer ... -
Quantitative Flood Risk Assessment in Drammenselva River, Norway
(Peer reviewed; Journal article, 2023)Floods are frequent natural hazards, triggering significant negative consequences for the economy every year. Their impact is expected to increase in the near future due to socio-economic development and climate change. ... -
Rehabilitation Planning of Water Distribution Network through a Reliability – Based Risk Assessment
(Journal article; Peer reviewed, 2018)The efficient and effective management of existing water distribution systems (WDSs) faces challenges related to aging of infrastructure, population growth, extended urbanization, climate change impacts and environmental ... -
Retrofitting of pressurized sand traps in hydropower plants
(Peer reviewed; Journal article, 2021)Unlined pressure tunnels in sound rock, combined with pressurized sand traps at the downstream end, allow for low-cost construction of hydropower tunnel systems. This design concept is utilized in hydropower plants across ... -
Riprap Protection Exposed to Overtopping Phenomena: A Review of Laboratory Experimental Models
(Peer reviewed; Journal article, 2022)There are increasing demands from dam safety regulations and guidelines to upgrade the rockfill dams, especially in Norway where over 180 large rockfill dams are present. To protect the hydraulic structure against overtopping ... -
The Story of a Steep River: Causes and Effects of the Flash Flood on 24 July 2017 in Western Norway
(Peer reviewed; Journal article, 2021)Flash floods can cause great geomorphological changes in ephemeral fluvial systems and result in particularly severe damages for the unprepared population exposed to it. The flash flood in the Storelva river in Utvik ... -
Susceptibility of Hydropower Generation to Climate Change: Karun III Dam Case Study
(Journal article; Peer reviewed, 2019)Climate change can cause serious problems for future hydropower plant projects and make them less economically justified. Changing precipitation patterns, rising temperatures, and abrupt snow melting affect river stream ... -
Suspended Sediment Source and Transport Mechanisms in a Himalayan River
(Journal article; Peer reviewed, 2024)The process of estimating sediment load has been a daunting issue in hydraulics and the water resource field. Several methods exist for predicting the sediment load in a catchment or river, but the majority of these methods ... -
The acoustic properties of suspended sediment in large rivers: Consequences on ADCP methods applicability
