TY - JOUR ID - TI - Analysis of Morphological Features of Sargalu Region in Sulaymaniyah Governorate, North of Iraq, by using Geographic Information System AU - Ali Abdul-Jaleel Hussain* AU - Muaid Jassim Rasheed PY - 2021 VL - 62 IS - 4 SP - 1164 EP - 1176 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - It is an ideal area of research to examine related indicators to anticipate relativetectonic activities, where there is a broad range of geological formations withelements of different sedimentary rocks. This study includes assessing andevaluating the relative tectonic activities within the Sargalu area by using amorphometric approach, which involved the use of different indices that can explainand help understanding the geometry, development level, lithology, and structuraldisturbance on a sub-basinal level. The research was accomplished by using ArcGIS10.5 hydrology tools to design the drainage system of each studied stream. TheAdvanced Spaceborne Thermal Emission Radiometer (ASTER) satellite imagerydata and the Digital Elevation Model (DEM 90m) were used. Moreover, GlobalMapper and Statistical Package for the Social Sciences (SPSS) were applied. DEMdatasets of ASTER were used for watershed delineation. Also, 14 sub-basins weredelineated in the Sargalu area. Morphometric indices used include Shape RelatedIndices, such as Rc, Bs, Rf, Ls, Re, T, and Af. Basin asymmetry factor (Af) andseveral geomorphic indices were also utilized. Based on the shape related indices(Rc, Rf, Re, Ls, and Cc), the results were found to be similar and, for most subbasins,had an elongated nature. The elongated basins are connected withtectonically active areas, while the circulated basins are connected with thetectonically undisturbed environment.
