Abstract: Morphometric analysis is the best method to understand and determine the shape, size, and dimension of a watershed. Conducting this analysis required a wide variety of quantitative measurements and mathematical analysis presenting valuable data related to hydrological characteristics of the watershed. Using GIS technique and Digital Elevation Models (SRTM-DEM) images were extremely facilitated the method and precisely boosted the results. Morphometric parameters were utilized of the Abbasan watershed determining hydrological properties and runoff assessment. The watershed area, of Abbasan covers (878.34) km2, the calculations of dimension, shape, and compactness coefficient are done which indicated elongated shape, low runoff intensity and low erosion rates. Most of the morphometric parameters were computed and analyzed such as relief properties, stream network, and drainage pattern characteristics which is referring to (2555) m elevation, low-moderate relief, six stream orders, and three types of drainage patterns respectively. Rectangular drainage patterns occupied a large area followed by Dendritic and Trellis patterns in terms of area. This study has given a comprehensive insight into the whole morphometric aspects of the Abbasan watershed.
