| Abstract | ||
| This research aims to study the morphometric analysis of Al-Teeb fan in southeastern of Iraq based on visual interpretation of the enhanced Landsat TM image which is linked to digital interpretation by ArcGIS program after making georeferencing to them. Drainage network was created from 30m (DEM) result from satellite data using GIS to match the shape of the fan with its related discharge streams. ArcGIS program was used to calculate the Morphometric measurements to clarify the characteristics of (areal, sharpness and ruggedness). The only five order streams indicate that fan received more water from rainfall as surface runoff. The catchment area has been delineated by drainage pattern extracted from DEM analysis. The analyses indicate the littleness in vegetation cover and high permeability and therefore make increase the rain fall infiltration. The fan basin move away from the circular form and the proximity of the elongated shape and so the basin has shape of triangle. Also, fan basin surface has steep slope surface and gentle ruggedness terrain. Key words: Fan morphometric, Remote sensing, GIS | ||
