Erosion Intensity

This paper analyses the state of erosion intensity in the Vlasina River Basin, the right tributary of the Juzna Morava River. To determine the erosion intensity (Z) and sediment production, the Gavrilovic method was used, in combination with the bare-soil index (BSI), with the application of geographic information systems (GIS) and multispectral satellite imagery. An erosion coefficient of 0.31 has been identified in the territory of the Vlasina River Basin, which has an area of 1,061.72 km?. The prominent vertical fragmentation of the relief, large amount of precipitation in the source parts, density of the river network (1.65 km/km2), which is above the average river network density in Serbia, as well as inadequate land exploitation, are the main reasons why it is necessary to monitor the erosion intensity in the Vlasina River Basin. The annual production of the sediment is 462,496.30 m?, while the value of specific sediment production is 435,47 m?/km?/year. This study represents the attempt to apply modern technologies to d1etermine the intensity of erosion in the Vlasina River Basin, and the results obtained could be used for more adequate management of land and water resources, sustainable planning of the forest ecosystems and environmental protection.

Erosion Intensity

The aim of this research was to analyse the changes in the soil erosion intensity caused by erosion control works (ECW) in Grdelica Gorge (The South Morava River) in the period between 1953 and 2016. For the purpose of quantifying the erosion intensity changes, the erosion potential model (EPM) was used to calculate the annual gross erosion (W), sediment transport (G), and erosion coefficient (Z) in the study area. As a result of the performed technical and biotechnical erosion control works, there was a general decreasing trend in the intensity of soil erosion processes in the last 63 years. The specific annual gross erosion in Grdelica Gorge was 1920.34 m3/km−2/year−1 in 1953, while in 2016 it was 492.42 m3/km−2/year−1. The specific sediment transport was 1421.05 m3/km−2/year−1 in 1953 and 364.39 m3/km−2/year−1 in 2016. Due to the changes in the intensity of erosion processes, the specific annual gross erosion in the study area decreased by 1427.92 m3/km−2/year−1 and the specific sediment transport by 1056.66 m3/km−2/year−1. The value of the erosion coefficient was reduced from Z = 0.84 in 1953 to Z = 0.32 in 2016. The results show that there is a significant correlation between the soil erosion intensity (erosion coefficient) and ECW (biotechnical works) performed in Grdelica Gorge. The permanent control of erosion processes in Grdelica Gorge is very important for torrential flood prevention and protection of two very important traffic routes (Belgrade-Skopje-Athens railway and motorway—Corridor X), as well as settlements, local roads, and other facilities in this area. Furthermore, these results are the basis for future water mana­gement projects, soil and environmental protection, spatial planning, agriculture, and other human activities.

Erosion Intensity

The aim of this research is to determine the change in the spatial distribution of erosion intensity in the territory of the Jablanica River Basin in the period 1971–2016 caused by land use and demographic changes. The Erosion Potential Method (EPM) was used to quantify changes in erosion intensity and to estimate the total annual sediment yield. The research results show that the value of the erosion coefficient decreased from 0.432 in 1971 to 0.360 in 2016. Specific annual gross erosion in the Jablanica River Basin was 654.41 m3/km2/year in 1971, while in 2016 it was 472.03 m3/km2/year. The analysis of proportional changes was used to determine demographic changes and land use patterns in the basin area. In terms of the scale and intensity of the erosion process, three types and one sub-type of population dynamics of settlements and land use changes were distinguished, respectively: progressive, stagnant, regressive and dominant regressive. It was concluded that the results show the significance of demographic and land use changes in the control of the intensity of erosion. The Soil Erosion Map may be useful to planners and land use managers to take appropriate decisions for soil conservation in the basin.

In this paper the results are presented of estimation of T-year specific discharge of several streams in two regions in Slovakia. The Qmax time series used in the study were observed at water gauges from lowland Slovak part of the Morava River basin, and from the mountainous Belá River basin. For estimating the design values, we have studied the use of only one type of probability distribution, namely the Log-Pearson Type III Distribution (LP3 distribution). The use of only one type of distribution brings several benefits, e.g. possibility of the regionalization of the distribution parameters (in this study skew coefficient). In the first step the design values of the specific discharge series qmax (with historical data) were estimated and regional skew coefficients Gr of the LP3 distribution were computed. Regional skewness coefficient Gr was estimated to be 0.38 in the Morava River region, and 0.73 in the Belá River region. In many cases the estimate of the 1000-year specific discharge is two times higher than the value of the 100-year specific discharge. Then we have derived the empirical relations between station skew coefficient G and the elevation of the water gauge. In the second step we have derived the empirical relationships between 1000-years specific discharge q1000 and the elevation of the water gauge for both regions separately. The derived empirical regional equations can be used to estimate the 1000-years specific discharge of other streams in the region.

Researchers associate the medieval archeological artifacts of the Middle Trans-Urals, whose pottery bears cord impressions, with the Chiyalik, Molchanvo and Yudina Cultures. Despite the large number of artifacts that have been studied, many questions remain open. These include the status, chronology, and interaction of the Molchanovo and Yudina antiquities, as well as the evolution and specifics of their pottery complexes. Publication and analysis of the ceramic collections from Vak-Kur, the largest burial ground of the Yudina Culture, contribute to addressing some problems related to «the Corded Ware cultures». The Vak-Kur burial ground is dated to the 10th–11th centuries based on the assemblage of the associated goods. It is located in the south-eastern part of the Yudina Culture areal, on the right shore of the Tobol River. For all the time of excavations in the area of the ne-cropolis, 220 burials have been studied. The dead were buried in shallow pits according to the ritual of inhuma-tion, on their backs. A specific feature of the funeral ritual is breaking of a part of the accompanying equipment and use of funerary masks. Decorative and morphological features of 143 Yudina vessels have been examined. The tableware has been categorized according to four topographic groups after excavations 3 to 6. It has been noted that, despite the similar shapes of pots, and ornamental proportions and patterns, the pottery from excava-tions 3 to 6 demonstrates a different frequency in use of such elements in the décor as the cord and figured stamps. The biggest differences were detected between the ceramic artifacts found in excavations 4 and 6. It was suggested that the differences in décor between pottery from different excavations are determined not by their asynchronous nature, but by the existence of several tribal sites in the area of the Yudina necropolis. The com-parison of ceramic collections from the Vak-Kur burial ground with those from the medieval burial and settlement sites of the Yudina Culture showed that the pottery from the necropolis is most closely related to collections from the Plamya Sibiri 6 and 7, and Antonovo 1 settlements located in the Tura River basin. These sites were dated by their investigator to the earlier period (6th to 9th centuries) and attributed to the Molchanovo Culture. Based on the significant similarity between the pottery of the named sites and the dishware of the 10th to 11th centuries from excavation 4 of the Vak-Kur burial ground, a revision of the chronology and cultural attribution of these sites has been proposed.

In the Pestan River Basin, the right tributary of the Kolubara River, a complex degradation of natural conditions has been expressed over the decades. The exploitation of lignite in the Kolubara Coal Basin, which is in large part located in the territory of this basin, as well as accompanying activities related to it, are the dominant activities that lead to the degradation of soil and hydrological conditions. If other land use types are added to this, it can be concluded that the land cover in the studied territory suffered significant negative changes. The above mentioned activities have led to land loss and deterioration of its quality, and the regulation works due to dislocation of the Kolubara watercourse into the Pestan riverbed have caused numerous degradation of landscapes, reduced the basin area and shortened its watercourse, led to morphological changes of the river network and deterioration of the surface water quality. The aim of this paper is to perform a geospatial analysis of all areas in which the degradation of soil and hydrological conditions is present, in order to prevent their further degradation and proper management of these areas.

In this paper, the authors summarise the land use changes in the upper reaches of the Krupá river catchment, which is a left tributary of the Morava River. During last 70 years, the catchment was exposed to many important historical events that have been inscribed in the physique of the landscape in a very interesting way. The land use changes, which occurred during the last eight decades in the subcatchment of the Krupá river basin, have been analysed using historical maps, cadastral maps, and both historical and recent aerial photographs of the area. The next step is to estimate, through the CN method and DesQ hydrological model, how the runoff processes in the Krupá River catchment could be influenced by the land use changes.
