Online symposium on Current Research in Hydropower Technologies

Ten students from NTNU/HydroCen made their presentations online when Kathmandu University decided to hold their 10th international symposium on Current Research in Hydropower Technologies (CHRT) online.

The conference was established in 2010 to be a meeting place for students, experts and researchers in hydropower technologies.

Every year a delegation from the NTNU (the Norwegian University of Science and Technology) visits the Turbine Testing Laboratory at Kathmandu University and participates at the symposium. This year, due to the situation with COVID 19 virus all the presentations and key notes are published online.

–It is an achievement to be able to hold this conference for the 10th time. It is impressive to see how the symposium has evolved and to see the that so many people are meeting and sharing information in order to build knowledge for each other, said Professor Ole Gunnar Dahlhaug.

Kathmandu University is one of the partners in HydroCen, and several HydroCen-projects are researching issues linked to hydropower in the Himalaya-region. The students presenting at the conference are also linked to these projects.

– Nepal and Norway have in common that we have tall mountains and lots of water.  I believe that hydropower could impact Nepal in a similar way that Norway has developed from hydropower, only much faster than our 100-year-story of hydropower research, said Dahlhaug.

But hydropower in the Himalayas raises many questions concerning technology, environment and sustainability.

–We would very much like to contribute, as a partner, so finding the answers to the questions that will come up in the decades to come, he said.

Here you can see Professor Dahlhaugs Key-note speech where he talks about the special relationship between NTNU and Kathmandu university, and how Nepal and Norway have hydropower in common.

Here is the entire program for the conference:
