2.4 Conclusion
The study area Shivkhola watershed possesses a wide range of elevation between
300 m in the south-east and 2,040 m in the north. A large part of the watershed is
lying between the altitude of 400 and 600 m. The steepness of the slope varies
signi
cantly from place to place and its characteristics mostly depend on the
drainage density. The left hand side of the river Shivkhola is less steep in
