Hydroplastic response of a square plate due to impact on calm water
(Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
Hydropower
(Chapter, 2021)Hydropower has a very long tradition in many countries and was first used to provide working power for grinding corn, sawing timber and other previously manual tasks. The development of the modern turbine took a big step ... -
Hydropower Bidding in a Multi-Market Setting
(Journal article, 2018)We present a literature survey and research gap analysis of mathematical and statistical methods used in the context of optimizing bids in electricity markets. Particularly, we are interested in methods for hydropower ... -
Hydropower impacts on reservoir fish populations are modified by environmental variation
(Journal article; Peer reviewed, 2018)Global transition towards renewable energy production has increased the demand for newand more flexible hydropower operations. Beforemanagement and stakeholders can make informed choices on potential mitigations, it is ... -
Hydropower operations in groundwater-influenced rivers: implications for Atlantic salmon, Salmo salar, early life stage development and survival
(Journal article; Peer reviewed, 2016)During their early life stages (egg maturation, hatching, alevin development), between late autumn and early spring, young Atlantic salmon are exposed to surface-groundwater interactions in the hyporheic zone and may depend ... -
Hydropower Production in Future Climate Scenarios: The Case for Kwanza River, Angola
(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
(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 ... -
Hydropower Project Ventures: Testing International Waters
(Journal article; Peer reviewed, 2012)A vanguard project is an effective mechanism for testing new opportunities to deploy existing technologies into new markets in an effort to realize growth. Typically such endeavors are motivated by organizational needs to ... -

Hydropower reservoir management using multi-factor price model and correlation between price and local inflow
(Journal article, 2018)Hydropower producers with reservoir capacity have a special challenge when it comes to weighing the short-term profit from selling power in the day-ahead spot market against waiting for better electricity prices. In this ... -
Hydropower Scheduling with State-Dependent Discharge Constraints: An SDDP Approach
(Peer reviewed; Journal article, 2022)Environmental constraints in hydropower systems serve to ensure sustainable use of water resources. Through accurate treatment in hydropower scheduling, one seeks to respect such constraints in the planning phase while ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
(Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long-term impacts ... -
