Morphometrical Features of the Vis Island

Abstract

[EN]The object of this study are hillslopes of the Vis island. The slopes can be defined as relief surfaces determined by geographical position, slope inclination (related with horizontal surface) and slope aspect. Recent slope shapes can be defined as result of series of natural and anthropogenic factors during relief genesis and evolution. It is possible to correlate slope characteristics with geological structure and other natural geographic features (climate, soils, vegetation etc.) using geomorphometrical analysis. The main aims of this study are: a) analysis of morphometrical relief indicators (hypsometry, slope inclination and slope aspect), b) analysis of relationships between morphometrical indicators, and c) analysis of relatioships between morphometrical parameters, structural and lithological features, in order to gain more detailed understanding of exogeomorphological and morphostructural features of the investigated area. The final intention is to assess extent and intensity of dominant geomorphological processes. Special attention was given to detailed geomorphometrical analysis of morphostructures of Vis island in GIS environment based on DMR. Applied geomorphometrical relief analysis included use of different methods for precise calculation of numerical relief parameters of investigated area, which enabled mutual comparison of specified parameters and comparison with maps of tectonic units and lithology. The aim of this approach is more exact analysis and interpretation of morphometrical relief parameters as indicators of characteristics of endogenous and exogenous processes in the investigated area.
