The watershed is a topographical and hydrological area on which the precipitation occurs and drains towards the common point and there is a harmony among the land-use, soil and geomorphology. So it is more rational to adopt the watershed as a development unit. The morphometric characteristics are commonly used to develop regional hydrological models particularly for unguaged catchment. Gagadio watershed having 521.55km2 drainge area located in Amreli district of Gujarat. Gagadio river is a major left bank tributary of Shetrunji river. Using ArcHydro tool in ArcGIS software, Gagadio watershed and its fourteen subwatersheds were delineated. The basic morphometric parameters (basin area, basin perimeter, basin length, total number and length of streams of each order) and linear morphometric parameters (bifurcation ratio, drainage density, stream frequency, texture ratio, length of overland flow) were calculated for fourteen subwatersheds. The values of mean bifurcation ratio in all subwatersheds indicates less structural disturbance in drainage pattern of subwatersheds. In all fourteen subwatersheds, observed values of drainage density and stream frequency are moderate. Values of texture ratio reflects very course drainage texture in all subwatersheds. Overland flow length in all subwatersheds are nearly 1 which are low.
