Annually, soil erosion imposes significant hazards by raising soil fertility and filling reservoirs with sedimentation in the Rawanduz River basins, Iraq. The Rawanduz watershed consists of seven sub-basins. Therefore, it is important to consider areas in these basins that are vulnerable to soil erosion for preventive hazard action. ALOS PALSAR DEM 12.5 m-resolution data was used to analyze morphometric parameters in the study area. Linear, aerial, and relief morphometric parameters were determined using GIS techniques. A set of 15 parameters were studied, including slope (S), drainage density (Dd), texture ratio (T), relative relief (Bh), stream frequency (Fu), infiltration number (If), ruggedness number (Rn), length of overland flow (Lo), constant of channel maintenance (C), relief ratio (Rh), elongation ratio (Re), shape factor (Bs), form factor (Rf), circularity ratio (Rc), and compactness coefficient (Cc). Then, an Analytic Hierarchy Process (AHP) was used to classify sub-basins according to their susceptibility for soil erosion and important morphometric parameters that have an important influence on soil erosion. The results of the model show that erosion is highly affected by the slope and drainage density in the region of interest, mainly. The results of the AHP set model showed that sub-basin 2 was highly susceptible to soil erosion. We conclude that these results could be useful to various stakeholders such as farmers, water resource managers, conservation planners, and policymakers for better management and decision-making activities.

Deformation monitoring has conventional increasing consideration in recent years due to its great importance in modern engineering. Darbandikhan town was hit by a strong earthquake on 12th November 2017 which is the Sarpol-e Zahab earthquake. Interferometric Synthetic Aperture Radar (InSAR) technique has been used to investigate Darbandikhan town stability and the surrounding areas of the Kurdistan region in Iraq. The purpose of this research is to estimate the ground vertical displacement induced by the earthquake as well as the east-west deformation components. Moreover, previous research covered more of Iran’s side country that the earthquake had an impact on with little on Iraq’s side (Northern-eastern of Iraq), so it was worth researching on Darbandikhan town and surrounding structures to estimate the displacement on its infrastructures. For this study, two pairs of Sentinel-1 Synthetic Aperture Radar (SAR) images are used from each ascending and descending tracks over the study area to validate the work. Then, two differential interferograms are created from these images, along Darbandikhan town and the surrounding areas. These differential interferograms are then converted to line of sight (LOS) displacements using open source software (SNAP 8.0). The overall vertical displacement of the residential area of Darbandikhan was estimated from -4 to -10 cm after the earthquake, and the overall east-west displacement was ranging from 2 to 6.4 cm. The current study does not only examine the northern east of Iraq but the whole area of Iran and Iraq in general that lies within the influence of the earthquake. This research could be useful to estimate the overall deformation of Darbandikhan town in particular and the whole area in general. Therefore, the authorities and civil engineers could think of more sustainable buildings and structures before they start to plan within the area of earthquake impact.

Management of natural resources is becoming a very high demand in the future than any other times. Therefore, it is very crucial to make a deep study and analysis of the area of interest through geo morphometric study, which is a significant tool for controlling watershed natural resources. In this paper, the morphometric parameters of Rosti valley watershed are analyzed and evaluated by Horton and Strahler methods. Image processing has been done for ASTER image to create Digital Elevation Model (DEM). For morphometric interpretation with evaluation of different morphometric parameters, the Advanced Space Borne Thermal Emission and Reflection Radiometer (ASTER-DEM) image was used. The Rosti basin's geo morphometric analysis was delineated, using image processing and GIS by calculating linear, aerial and relief parameters. The Rosti watershed is stretched over an area of 201.41 km2 and the watershed slope is varying from 0% to 68.97 %. While the bifurcation ratio extends from 0.96 to 2.34 showing the geological structure's influence and the structural disturbances increased. However, the result of the form factor is 0.39 denotations that the basin shape is the total number of stream segments equal to 1424 Segments. This paper endeavours to use the effective methods, based on geomorphometric analysis along with the proper tools and software such as GIS to achieve the highest level of certainty in regard with the area of interest ''Rosti Basin''.
