Abstract

Annex to the interpretation of the role of geoenvironment in the formation of extreme discharges of the Rosomacka River provides exact and empirical evidence of the significance and the need for its knowledge. For hydrologically unstudied watercourses, especially for those which do not have continuity of discharges, the knowledge of the role of geoenvironment in the emergence of their extreme discharges contributes to a more realistic response to practical water management issues, protection against adverse effects of waters, defining the ecological aspect of watercourses under the influence of various changes in the near future (climatic, anthropogenic, hydrological), preserving the quality of river water, meeting the requirements of the EU Water Framework Directive 2000. The aim of the paper is to understand better the river systems and their runoffs in the form of high and low waters or complete drying up of hydrologically unstudied but also of hydrologically studied watercourses, and through the representation of the role of geoenvironment. On the concrete example of the Rosomacka River, a hydrologically unstudied watercourse, the significance of geoenvironment in the interpretation of its extreme discharges was emphasized. The contribution of the following elements of geoenvironment of the basin area was analyzed: lithological, neotectonic, hydrogeological and morphological. The research method is based on field research, quantitative geomorphological analysis, systematization and synthesis of the obtained results, as well as the analysis of published papers. Additionally, the contribution is reflected in emphasizing the need for communication between experts of various specialties dealing with hydrographic systems.

Highlights

River waters are of great importance for the entire range of needs of a modern man, and for the protection against their adverse effects, as well as active control of discharges during periods of low water
The characteristic of the Rosomačka River is to dry up at two sections (Figure 2): the first one is in the middle course, in the area of the karstified Middle Trias limestones, while the other one is in the lower part of the course in the alluvium of the Visočica River (Figure 3)
A significant element in the formation of extreme discharges of the Rosomačka River is the geoenvironment of the basin area

Summary

Introduction

River waters are of great importance for the entire range of needs of a modern man (water supply of population and industry, irrigation, electricity production, biodiversity conservation, fishery, etc.), and for the protection against their adverse effects (torrential floods), as well as active control of discharges during periods of low water. Developed countries tend to know the regime of all watercourses, low, high, perennial and ephemeral, or all that are important for the local community or country. One of the important elements of the regime of each watercourse are its extreme discharges, that is, high and low waters. High and low waters fall into frequent natural disasters both worldwide and in this country. Their intensity and frequency of occurrence in the territory of the Republic of Serbia places them in the category of potential limiting factors in the economic and ecological sphere of further development
