Slope Classification and Its Impact on Human Activities in the Jumana District – Erbil Governorate

Abstract

The study dealt with the geomorphological analysis of the ground slopes in the district of Juman, which amounted to 1065 km 2, and the study aims to identify the natural characteristics that drew the features of the terrain and to know the regressive characteristics prevailing in the region, and the study showed that the largest area represented by areas of extreme shade as it amounted to (640.14 km2) of the total area of the study area, while the category of medium shadow areas occupied the least area, amounting to (173.04 km2) of the total area of the study area, and this indicates that the region is a shadow area and receives Small amounts of solar radiation and this leads to an increase in the activity of weathering and erosion processes due to increased humidity rates, this category is clearly spread in the northern part and the southwestern part of the study area with a northwest - southwest orientation, and through the classification of slopes and matching them with the zinc classification, it was found that the classification of Yonk is the most appropriate slope classifications with the topography of the study area, as it formed the highest areas within the slope category (18-30) within the steep lands, and the lowest category Within the flat lands with a slope angle (0 – 2) and this indicates that the majority of the areas of the study area are.
