vers). And LP is the overall length of the reach.
For calculation of river sinuosity Index river is divided into four
segment as A, B, C and D (Fig. 3) and polygons convert into the
polylines and the field geometry is calculated to know the river
length and Measure Tool is used to measure the shortest length
and Field Calculator are used to calculate the sinuosity index in
ArcGIS environment in Table 1 (Morisawa, 1985).
Some GCP (Ground Control Point) has selected on the left bank
of 1972 river course and based on the measured direction distance
between GCP and river course is measured during study and it has
been estimated that how much river in which direction is shifted
during study duration.
