Geomorphology of Adirish basin in Amadiyah, Northern Iraq, Using Remote Sensing Techniques and Geographical Information System (GIS)

River basins represent important geomorphological features. They are supplied with runoff and ground water flow. The geometric, morphological, surface and stream density characteristics of the aqueduct are main objectives of the study of river basins because of their importance in explaining the geomorphological appearance of river. The Adirish Basin was studied by using quantitative analysis remote sensing and GIS techniques using Erdas Imagine V.9.2 and GIS software V.10.1. From an analysis of river features of adirish basin through coefficient of elongation ratio, circularity ratio and basin shape parameters, it turns out that the basin far from the rectangular shape and rotation, because their values are 0.2, 0, respectively. It is approach the triangle shape because lese for the basin shape coefficients which reached 0.5217. The stream order of the study area reached five order, and the rate of bifurcation ratio was within the normal range. The stream frequency in the basin has reached an advanced stage of activity, and the drainage texture indicates that the basin is within the soft textile, it represent the prevailing drainage pattern is the type of dendritic.
