Introduction
1.2 Importance of Technology
Nepal is characterised by
its hills and mountainous
topography and highly difficult
hydrogeological conditions.
Eighty three per cent of the
country’s area consists of
mountains and hills. Difficult
terrain, poor accessibility
coupled to sparse and scattered
settlements is a major hurdle
in delivery of essential services
and rural development. Up to
the late 1950s, foot and mule
trails were the only means of
transport throughout Nepal.
Since then, efforts have been
made to connect various parts
of the country by developing
road networks. The efforts
