Current Research in Hydropower Technologies, CRHT-X

April, 2020

It is our pleasure to welcome you to CRHT X’20, 10^th International Symposium on Current Research in Hydropower Technologies. The symposium aims to bring together students, researchers, professionals and experts in hydropower sector and other renewable energy fields to share their experiences and research insights. Furthermore, we are extremely delighted to be hosting this event for the 10^th time.

Unlike previous years, due to the COVID-19 pandemic this year, the conference is planned to be conducted in a web-based module. All the presenters were asked to submit their narrative presentations along with the full papers. After a thorough review by the experts in the related field, selected research and technical papers are planned to be published in Journal of Physics: Conference Series as a part of conference proceedings.
