Analysis of Geomorphological Slope Characteristics in the Sagrma Mountain Range

Abstract

Slope is a fundamental characteristic in geomorphology, significantly influencing a range of geomorphological factors and processes.[1] This study aims to conduct a quantitative analysis of the primary slope characteristics within the Sagrma mountain range. The study area is a rugged mountain range featuring diverse geomorphological forms, covering an area of 339.7 km² with a length of 52.7 km. It constitutes the topographical boundary between the mountainous and semi-mountainous zones, extending from Darbandi Basara to the village of Barkal. The region's topography varies in elevation from 900 to 1872 meters. The slope gradient, measured according to Young's scale, ranges from 0 to over 45.1 degrees. This topographical variance results in distinct differences in slope properties—including slope degree, aspect (direction), form (shape), and hillshade (solar illumination). Key findings from the analysis indicate that the northern slopes of the range generally possess a lower slope degree compared to the steeper southern slopes. Furthermore, a significant seasonal variation in shaded areas was identified; the area experiencing extensive shading measures 19.6 km² during the summer, increasing to 59.7 km² in the winter.
