Abstract : The study area Tapi River catchment covers 63,922.91 Sq.Km comprising of 5 five Sub-catchments:
Purna river catchment (18,473.6 sq.km) Upper Tapi catchment (10,530.3 sq. km), Middle Tapi catchment (4,997.3 sq km),
Girna river catchment (10,176.9 sq.km) and lower Tapi catchment (19,282.5 sq.km.). The drainage network of 5 Sub
-catchments was delineated using remote sensing data. The morphometric analysis of 5 Sub-catchments has been
carried out using GIS softwares – ArcMap. The drainage network showed that the terrain exhibits dendritic to
sub-dendritic drainage pattern. Stream orders ranged from sixth to seventh order. Drainage density varied between
0.39 and 0.43km/ km2and had very coarse to coarse drainage texture. The relief ratio ranged from 0.003 to 0.007.
The mean bifurcation ratio varied from 4.24 to 6.10 and falls under normal basin category. The elongation ratio
showed that all catchment elongated pattern. Thus, the remote sensing techniques proved to be a competent tool in
