After finishing our bachelor studies in industrial engineering, both took the path of renewable
energies as specialization. Therefore, the opportunity of working in a project which sought the
resolution of an ecological problem involving hydropower dams has been really valuable for us, not
only for the technical knowledge acquired but also for the experience as a whole.
The project was supervised partially by Vattenfall, an international energy company that works
towards a fossil-free future. Although the project was originally proposed by Fiskvägsteknik AB,
Vattenfall served as intermediary between this company and us. In particular, we would like to
thank Bengt Hemström and Mats Billstein for the great opportunity and for all the help provided in
the process. They have been important pillars in the progress of the report.
The other part responsible for the supervision was the University of Gävle. Taghi Karimipanah and
Abolfazl Hayati have worked hard to provide us with enough resources for the competition of the
tasks, including interesting papers and computer processors for the simulations, as well as helping
us with all the administrative procedure needed for a master thesis. For all the effort made, we
wanted to thank them thoroughly.
The support of our family and friends has also been important for the development of this project.
Finally, we would like to thank each other for the hard work put throughout these past months and
the comradeship shown in the development of the thesis. From this experience we learnt to work
and solve the problems found in the way as a team, helping one another should the situation
require it.
