Abstract
Longitudinal profile of a river provides the idea about tectonic activity and
local terrain condition through which the river is flowing. It provides the
information about the change in slope, natural breaks, and knick points in
river course and also provides vivid idea about the cycle of development of
the river. To understand minutely the local geomorphic condition, the
longitudinal profiles of other major tributaries of Sanka River has been
considered. By comparing the linear, logarithmic, exponential, and power
regression models with distance against elevation data and geologic
structure, it has been possible to understand the shape of lengthy profiles.
The best fit model has been decided on the basis of derived R2 or Coefficient
of Determination and the model which provides minimum sum of square of
residuals and standard deviation have been considered as best fit model. It
has observed that longitudinal profile majority of the streams fits with
exponential model except Sanka River and Srigi Nala fits with power
regression model and Dhudi Jhor fits with linear regression.
