Abstract

Introduction and Background Geomorphic quantitative indices are useful for identifying specific features of a particular region, especially in tectonic studies. One of these indicators is the hypsometric curves (hypersometry) and the hypersonic integral which is used to indicate the potential of the regions in terms of tectonic activity in order to assess the areas under Erosion and sedimentation of drainage areas. Aims The aim of this study investigates the physical characteristics of the catchment areas of the Makran coastline in terms of their Erosion characteristics and sedimentation using non-dimensional hypsometric curves. Methodology In this study, for extraction of the network of streams and their ranking, a digital elevation model of the region with Resolution of 10 meters was ranked according to the Australian method. In the Python programming environment, it was coded to calculate the values of tables and plot the dimensionless hypersonic curves for analyzing the Erosion state And sedimen-tation in the entire surface of the watershed of Makran coastal areas as well as drainage basins. Conclusion Measuring the Hypsometric Curve Index shows that they are balanced in the main basin of geomorphologic processes. Considering the values of the table and drawing of the hypsometric curve of the whole area of the region, it shows a balanced expansion of plain and altitude. But calculating the hypsometric curve and integral in the sub-basins of the study area shows that the northern part of the sub-basins, tectonic processes are superior to Erosion processes. If in the southern sub-basins, Erosion processes take precedence over tectonic processes or geomorphologic processes act in a bal-anced manner. With the influence of geological parameters and the creation of tectonic anomalies, the land will be changed and Erosion in the basins will be changed. The total thickness of the drainage basin is 20%.
