Hydropower can be a source of sustainable energy, provided environmental considerations are taken into account and economic aspects of hydropower design are appropriately addressed. Using concrete-lined pressure tunnels instead of steel pipes may be economically attractive but may also have limitations due to the low tensile strength of concrete. Cracking in concrete tunnel linings can lead... Read more

Biography

Yos Simanjuntak (1978,Pangkalan Susu, Indonesia) obtained his BSc (Cum Laude) in Civil Engineering from the Institut Teknologi Medan in Indonesia (2002), where he was later on appointed as an Assistant Lecturer. From May to July 2005, he worked as a Program Assistant for the United Nations WHO on the small island of Nias in Sumatra, which, as so many other communities surrounding the Indian Ocean, had suffered dearly from the devastating Tsunami during Christmas 2004. In 2007, he received a MSc (with Distinction) in Hydraulic Engineering at UNESCO-IHE in Delft, The Netherlands. In November 2010, he started his PhD research at UNESCO-IHE/TU Delft focusing on the design of prestressed concrete-lined pressure tunnels. He has guided several MSc students and given lectures on the topic of the Design of Settling Basins for the short course Small Hydropower Developments at UNESCO-IHE until 2014.
Currently, he works at Plaxis B.V in Delft as a Sales Support Engineer, in which his responsibilities are, among others, providing advice to new and existing customers worldwide on the various Plaxis software products. As the name suggests, PLAXIS provides solutions based on the finite element method dedicated to civil as well as geotechnical engineering.
