Morfometrijske značajke šireg područja Duvanjskog polja, Bosna i Hercegovina

Abstract

The objects of this study are the hillslopes in the broader area of Duvanjsko polje (Bosnia and Herzegovina). Slopes can be defined as relief surfaces determined by geographical position, slope inclination (related with horizontal surface), aspect, and degree of curvature (profile and planar).Recent slope shapes can be defined as results 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 morphometric relief indicators, b) analysis of relationships between morphometric indicators, structural and lithological features, and c) synthesis of all analyzed indicators in order to better understand exogeomorphological and morphostructural features of the investigated area. The final intention is to assess the extent and intensity of the dominant geomorphologic processes. Special attention was given to the detailed geomorphometrical analysis of morphostructures in the broader area of Duvanjsko polje in GIS environment based on DMR. The applied geomorphometrical relief analysis included the use of different methods for precise calculation of the investigated area’s numerical relief parameters, which enabled a mutual comparison of specified parameters and comparison with tectonic units and lithology maps. The aim of this approach is a more exact analysis and interpretation of morphometric relief parameters as indicators of the investigated area’s endogenous and exogenous processes’ characteristics.

Quantitative morphometric analysis of a river basin using GIS techniques: Case study of Miljacka River, Bosnia and Herzegovina

“…Methods and algorithms integrated into the ArcInfo program were used to calculate the slope of the terrain. The software program determines the values for each pixel (square area), in a way that it calculates the maximum rate of value change from that pixel to the neighboring ones that surround it Radoš, et al [2]. Slopes were determined by calculating the first-order derivatives of the values within a 3x3 square [24].…”

“…The analysis of the spatial distribution and coverage of certain categories of slope grade is important , considering their significance as indicators for the extent and intensity of morphostructural and exogeomorphological (denudation and accumulation) processes that influenced the genesis of slopes during the paleogeomorphological period, and are also an indicator of future impacts of the afore mentioned processes on their mutual relations [2]. The represented categories of slopes are presented with regard to the dominant morphological processes, and correspond to the classification accepted by the International Geographical Union.…”

“…The branch of geomorphology, based on an analytical-cartographic approach and quantitative characteristics of the Earth, is geomorphometry. It is an interdisciplinary field whose scientific and methodological basis is in mathematics, natural sciences and informatics [2]. Morphometry as such includes methods that are basically geomorphological, based on the principles of computer analysis of the G eographical Information System (GIS).…”

“…Considering the above, this tool encompasses a significant number of scientific disciplines, and in addition to being successfully used in scientific research, it is an indispensable part of work processes in the field of resource management, property management, development and spatial planning, cartography and infrastructure planning [1]. An indispensable part of modern geomorphometric analysis, which uses the wide possibilities of the geographic information system, is the digital elevation model of the terrain [2]. A digital elevation model represents a special type of geodata, in the form of a digital statistical terrain model with a series of known three coordinates [4,5].…”

“…The exposure of slopes in geomorphological processes is very significant, given that differently exposed slopes receive different amounts of short-wave radiation, in accordance with the apparent movement of the Sun, which affects the characteristics of climatic elements, and thus exo-geomorphological processes. Very warm exposures are south-facing slopes [2]. Figure 9 shows the distribution of exposures in the area of the Miljacka basin.…”
