Abstract

DEM analysis and profile extraction being used for finding many changes and phenomena in different regions, in this study dimensionless transverse half profile in two areas with different climates, in Fars province, Iran, were analyzed and compared. DEM data from 10 m intervals for 268 profiles selected from Jooyom and Doroodzan watersheds with respective warm arid and cold semi-arid climates. Profiles were selected from along main channels in each watershed with an average distance of 100 m. Dimensionless half profiles were clustered by the Discriminate method. Results demonstrated that the dimensionless half profiles in a warm and arid climate had more fluctuations and deviations of elevations from their means along profiles compared with those in warm climate and it could be a good way for comparing regions and climate recognition. It also shows that not just even too far weather conditions can be reflected in profiles but even two different regions in a same mountain chain but different weathers can clearly create different forms of watersheds.
