Abstract

Pera Magroon anticline is located within the northeastern of Iraq, covering area estimated by 958 Km2. The Landsat ETM+ false color composite imagery was produced by assigning [741] bands. It is used to distinguish alluvial fans in the southwestern limb of Pera Magroon anticline. Digital elevation models (DEM) were used for describing topographic features related to the alluvial fans, as well as, three dominations model (3D) was created from (DEM) and the Landsat ETM+ image.

 Arc GIS, hydro tool set was used to draw the drainage patterns, the area of study was covered by dendritic and parallel patterns. Contour lines across the fans form segments of ellipses reveal the pattern of tectonic activity at near a mountain front. The slope map depends on ITC system explaining the alluvial fans slope range between almost flat to gently sloping.
