In this study, remote sensing and GIS have been utilized for analyzing the morphometric characteristics of Kakan watershed. ALOS digital elevation model (DEM) of high spatial resolution (12.5 m) was used for preparation of stream network map and slope map of the study area. The Kakan watershed covers an area of around 47.44 km2 and has fifth order trunk stream were computed using Arc-Map 10.8.Totally, 131.61 km stream length has been extracted from ALOS-DEM; about 77.51 km was in first order, 25.03 km was in second order, 15.15 km was in third order, 6.58 km was in fourth order and 7.35 km was in fifth order. Results from stream number and mean stream length were in accordance with the Horton’s law of stream numbers and mean length. High drainage density (2.77 km/km2) of Kakan watershed revealed the well-defined channel network and would produce more runoff. Elongation ratio (0.783) and bifurcation ratio (0.26) of Kakan watershed shows elongated shape and youth stage of tributaries. This study would help the watershed department for planning and designing of sol water conservation measures.
