was necessary for Nepal to establish a research centre
to study and solve the complex issues and problems
associated with hydraulics and sediment in its Himalayan
steep rivers for sustainable water resources development.
Institute of Engineering, Tribhuvan University (IOE-TU)
in mid eighties planned for a Water Resource Research
Centre in Nepal. A hydraulic laboratory was set up
with joint co-operation between Norwegian University
of Technology and IOE-TU to carry out physical hydraulic
model study of headworks of 12 MW hydropower project.
The study continued for the period from1989 to 1991.
Dagfinn K. Lysne from Norwegian University
of Science and Technology (NTNU) was instrumental
in materializing this hydraulic laboratory. Similarly,
the physical model study for the headworks of 60 MW
hydropower project was also performed in the same
laboratory in 1996 to 1997. In order to provide continuation
to this work, Hydro Lab Private Limited (Hydro Lab)
was established with the financial support from the
Norwegian Agency for Development Cooperation (Norad).
Since the establishment, Hydro Lab has cooperation
with the Norwegian University of Science and Technology
(NTNU) and International Centre for Hydropower (ICH)
Norway. NTNU and ICH has been providing scientific
and technical support to the Hydro Lab.
The utmost importance of physical hydraulic scale
model is accepted and recognized because of the fact
that empirical formula and computer simulation are
not sufficient for a reliable hydraulic design of hydraulic structures for
headworks. As every river is different from the other
in terms of hydraulic behaviour and sediment transport,
model study becomes essential to ensure the sustainability
of designed headworks in a proposed location.
resource is the most important natural heritage of
Nepal. Nepal’s economy can be uplifted only
through harnessing the abundantly flowing steep rivers
in Nepal. Rivers are exploited by building structures
in the rivers for hydropower, irrigation and drinking
water projects. For the successful growth of water
resource development projects it is important to have
a centre which can fulfil the technical need for safe
and reliable design and operation of the projects.
Hydro Lab was founded to meet this need of the hour
and the country.
It is worth mentioning that Hydro Lab is the only
and first research organisation in
Nepal which is capable of performing physical hydraulic
model studies for water resources development projects.
Besides, it has developed expertise in hydro turbine
efficiency measurement and sediment studies.
