Abstract
Morphometric analysis is one of the important study in the natural sciences in general,
and geomorphology and hydrology in particular, to describe the nature of surface
drainage networks. The study area lies in north of Iraq, in Al-sulaymaniya province. With
an area of (1545.1) Km². And the geographic coordinates of the study area is (35°.28` -
35°.52` N). (45°.20`- 46°.24` E). DEM image were used with (90 m) resolution and the
drawing tools in ARC GIS program to delineate the total basin of the study area and
watersheds. We conclude that there were 3 main watersheds in the study area and that
group of parameters were calculated such as (linear, areal and relief properties)). The
study shows that the stream density was (1.77) Km/Km2 which mean that the study area
has a bad discharge of water and sediments, the elongation in the study area is (0.55) and
that mean the study area is closer to a rectangular shape, and the relief in the study area is
(25.1) m/Km and it reflects that the study area had rich effects of erosion and weathering.
