Nils Rüther
About
I have over 15 years of experience in the field hydraulic and sediment transport engineering in rivers as well as hydro power reservoirs. My research activity is focused on the 3D numerical modelling of hydraulics and sediment transport in fluvial environment. I have also been contributing to advancements in measurement technology for sediment transport quantification in fluvial environment. I have been studying sediment transport processes from a basic research perspective and applying the knowledge to engineering projects related to river engineering and hydro power design. Recently i have been involved in project for sediment management at hydro power plants.
I have experience in leadership which i gained during my time as the Head of the Hydraulic Engineering research group at the department of Hydraulic and Environmental Engineering in 2011-2016. In addition i was leading and involved in strategic research planning groups at NTNU. During my academic career I have been supervising (and co-supervising) 1 post doctoral student 10 PhD students, 4 of them have successfully finished, and over 35 MSc and BSc students.
The outcome of my work was published in over 14 peer-reviewed journal publications and over 25 conference papers. He has been reviewer for journals like JHE, JHR, AWR, WWR, Flow measurement and instrumentation, Geomorphology, IJSR, JoH, and many more. He has also been in the local organizing committee of 2 conferences and several workshops, as well as in the scientific committee of 3 conferences.
I am responsible for 2 Master level courses, Hydraulic design of Hydro power plants as well as headworks and sedimentation engineering in the Hydro power development course at our department.
