covers the large part of all the sub-watershed in Shivkhola. Generally mid-section
of sub-watersheds are attributed with the 2nd and 3rd order streams where the
drainage concentration and maximum number of stream confluence points pro-
motes the channel to flow with high discharge and so high rate of erosion is found
in this section.
