ANALIZA OPADÓW ATMOSFERYCZNYCH W UNIEJOWIE JAKO PRETEKST DO BADAŃ KLIMATU LOKALNEGO UZDROWISKA

Author(s): Marcin Gorączko,Mateusz Cukras / Language(s): Polish Issue: 7/2018

The article presents statistical analysis of precipitation data for the period 1980–2015 collected at the Uniejów station belonging to the Institute of Meteorology and Water Management of the National Research Institute. The analysis identified rainfall characteristics in the long term and in annual, seasonal and monthly perspective. The conducted research has shown that precipitation is one of the most variable elements of local climate, not only in terms of quantity, but also periods of their occurrence and duration. Having up-to-date knowledge of seasonal and long-term cyclicality of precipitation, as well as the possibility of significant deviations from average values, seems to be particularly important for a city whose current economic development is mainly dependent on the inflow of tourists seeking recreation and open-air entertainment. Furthermore, only a proper identification of the specific characteristics of the local climate of Uniejów provides the necessary basis for its protection against the effects of anthropogenic impact on the environment in this region.

Analiza zespołów eratyków w glinach lodowcowych i ich znaczenie w rekonstrukcji zasięgu lądolodu warciańskiego w obszarze między Piotrkowem Trybunalskim, Radomskiem a Przedborzem

Author(s): Piotr Czubla / Language(s): Polish Issue: 103/2015

Petrographic studies of indicator erratics in glacial sediments revealed the existence of at least two lithotypes of glacial tills (marked S and O/W), differing in source area of moraine material. The older one (S), represented by glacial till in Mąkolice, was deposited by the last advance of South Polish Glaciation in the area. The younger lithotype (O/W) includes glacial sediments of Middle Polish Complex. Among them, two varieties (sublitothypes), probably deposited by separate ice masses (but not ice streams), can be distinguished. These sublitotyphes are clearly recognizable only in the southern part of the area under research. Their relative spatial distribution and petrographic features confirm the validity of the conclusions based on the analysis of the relief, which suggests that the ice-sheet during the Middle Polish Glaciation (Odranian/Wartanian) entered the Piotrków region from two directions.

Analysis of human thermal comfort in Central European City during summer of 2015: A case of Novi Sad (Serbia)

Author(s): Dragan Milošević,Stevan Savić,Daniela Arsenović,Zorana Lužanin,Jelena Dunjić / Language(s): English Issue: 1/2020

Urban meteorological network (UMN) was established in the Central European City of Novi Sad (Serbia) based on "local climate zones" (LCZs) system. Physiologically Equivalent Temperature (PET) index was used for the assessment of outdoor thermal comfort in the "built" and "land cover" LCZ classes of Novi Sad. The index was calculated in the RayMan software based on the meteorological, physiological as well as building and vegetation data. Temporal analysis was performed for extreme heat stress days (PETmax ≥ 41 °C), extreme heat stress hours (PETav ≥ 41 °C) and days with occurrence of "tropical nights" (Tmin > 20 °C) during exceptionally hot summer of 2015. Our results show that extreme heat stress hours are the least frequent in compact midrise LCZ 2, followed by dense trees LCZ A. On the contrary, countryside (low plants - LCZ D) showed to be the most uncomfortable area during daytime followed by compact low-rise areas (LCZ 3). Tropical nights are the most frequent in midrise LCZs 5 and 2 (40-46 nights) and decreasing towards open, sparsely built and natural LCZs (6-8 tropical nights in LCZs A and D). This is almost 800% decrease and it has implications for health and recreation of urban population and emphasizes the need for UMN development based on LCZ system.

Analysis of land surface temperatures in the "Local Climate Zones" of Novi Sad (Serbia)

Author(s): Stevan Savić,Jan Geletič,Dragan Milošević,Michal Lehnert / Language(s): English Issue: 1/2020

In this study, the Local Climate Zones (LCZs) in Novi Sad, the second largest city in Serbia, are analysed as to surface temperature differences. The LCZs were delineated on the basis of the GIS-based method created by Geletič & Lehnert (2016). Land Surface Temperatures (LSTs) were derived from the satellites Terra, sensor ASTER, and LANDSAT-8. The thermal images were provided at a similar time (at about 9.30 AM) between 2002 and 2008 (ASTER) and between 2013 and 2017 (LANDSAT-8). Statistical analyses, including the analysis of variance (ANOVA) and Tukey-HSD test, were employed to reveal LST differences between the LCZs. The results indicate that in 84% of cases there were significant differences in LST between pairs of LCZs. Temperature differences between LCZs were the most pronounced in the summer season. In general, 8 (large low-rise), 10 (heavy industry), 2 (compact midrise) and 3 (compact low-rise) LCZs had the highest surface temperatures in Novi Sad. Contrary to this, LCZs A (dense trees), B (scattered trees) G (water bodies) were the coolest zones.

ANALYSIS OF RIVER REGIME AND WATER BALANCE IN THE ĐETINJA RIVER BASIN

Author(s): Dragana Milijašević,Ana Milanović / Language(s): English Issue: 2/2010

Water regime and water balance of the Đetinja River were analysed in this paper on the basis of a thirty-year data series on water level and discharge in the period from 1978 to 2008. The analysis of the Đetinja water level showed the mean annual water level of 53 cm in the mentioned period, whereas the lowest mean monthly water levels were in August, and the maximum mean monthly water levels in March and April. The average mean annual discharge of the Đetinja near Šengolj was 5.60 m3 /s of the observation period 1978-2008. The annual value of the average discharges was similar to the annual value of the mean monthly low and high waters. It has been concluded that the Đetinja River belongs to the moderate-continental variance of the pluvial-nival regime. The results of the research have shown that about 5.60 m3 /s of water is formed in the Đetinja Basin with specific runoff of 10.95 l/s/km2. Even though precipitation is not so low and ranges around 875 mm per year, the amount of the river inflow is smaller due to high evaporation of over 60%. Considering that the Šengolj hydrological station has been situated at 8.2 km from the mouth, and the station Stapari stopped working in 2002, there is an opinion that it would be significant to put the hydrological station in the part of the river course, as well as on larger tributaries.

Analysis of the relationships between the spatial arrangement of palaeovalleys and contemporary valleys of Central Poland in the light of GIS methods

Author(s): Aleksander Szmidt / Language(s): English Issue: 15/2016

W artykule przedstawiono przykład zastosowania wybranych metod GIS w celu wykazania związków pomiędzy przebiegiem dolin kopalnych oraz współczesnych na obszarze Polski Środkowej. Analizowany obszar w warunkach lądowych kształtowany był już w paleogenie i neogenie, natomiast największy wpływ na obecną rzeźbę powierzchni odcisnęły procesy morfogenetyczne w czwartorzędzie. W opracowaniach paleogeograficznych dla analizowanego obszaru często wskazuje się na możliwe zależności pomiędzy wykształceniem rzeźby współczesnej a jej podłożem, w szczególności zaś sieci dolinnej. W celu weryfikacji tej hipotezy, na podstawie archiwalnych materiałów kartograficznych oraz Cyfrowego Modelu Wysokościowego rzeźby współczesnej, zaproponowano schemat przeprowadzenia analizy z wykorzystaniem zestawu ogólnodostępnych narzędzi GIS. Z wyników przeprowadzonej analizy można stwierdzić, że główne doli- ny rzeczne Polski Środkowej w dużej części nawiązują swoim przebiegiem do kopalnej sieci dolinnej, gdzie związki te najlepiej są widoczne w przypadku dolin największych.

ANALYSIS OF THE SHORT-TERM AND LONG-TERM IMPACTS OF THE CORONAVIRUS CRISIS ON INTERNATIONAL CLIMATE POLICY

Author(s): Zehra Aşkınsena İLKILIÇ,Manuel Knoll / Language(s): English Issue: 2/2022

The coronavirus pandemic has caused far-reaching precautionary measures around the world. Governments’ attempts to get the coronavirus under control have led to the negligence of other important policy areas. Climate policy in particular has been significantly influenced and lost importance on the political agendas of states after the outbreak. Over time, the coronavirus will either disappear or lose its initial impact due to medical measures. Two years after the outbreak of the coronavirus, this paper aims to analyse and evaluate the short-term and long-term impacts of the coronavirus crisis on international climate policy. It is important to analyse how it has shaped international climate policy and what lessons can be learned for dealing with climate change. The analysis is based on the principles and regular functioning of the International Climate Change Regime.

Anthropogenic Denudation in Mining Areas on the Example of the Wałbrzych coal mining area (Sudetes, Poland)

Author(s): Jan Wójcik / Language(s): English Issue: 153/2018

In the 20th century Wałbrzych and its surroundings was the most prominent area of coal mining in the Sudetes. Nevertheless, in 1997 the mines were closed. An intensive anthropogenic geomorphic cycle commenced there in 1865 and lasted for 130 years. The biggest transformations in landforms occurred in two basins: Wałbrzych and Kuźnice, where a complex of anthropogenic forms was created from dumps and settling ponds, as well as subsidence depression. Among the dominant geomorphic processes related to anthropopressure were anthropogenic aggradation and anthropogenic denudation. Those processes resulted in raising and lowering of the land surface. Their intensity was diverse both in time and space. The average pace of anthropogenic aggradation in the years 1865–1996 amounted to 328 mm/year and was higher in the years 1945–1996 (439 mm/year) than during the period from 1865 to 1944 (255 mm/year). In both basins: Wałbrzych and Kuźnice, there was an increase in the intensity of this process in the years 1945–1996 when compared to the period of 1865–1944. The pace of anthropogenic denudation in the Wałbrzych coal mining area was considerably lower than the intensity of anthropogenic aggradation. During the research period, the land surface lowered, on average, by 66 mm/year, whereas the pace of the process decreased from 75 mm/year in the years 1865–1944 to 57 mm/year in the period 1945–1996. A considerably higher intensity of anthropogenic denudation was noted the Wałbrzych Basin (96 mm/year) than in the Kuźnice Basin (36 mm/year). It was determined that the anthropogenic denudation balance in the in the Wałbrzych coal mining area in the years 1865–1996 was positive (+262 mm/year). When comparing the scale of anthropogenic aggradation and denudation in several coal mining areas (Wałbrzych, Upper Silesia, Ostrava-Karvina and Ruhr), it needs to be emphasized that in the research area the intensity of those processes in the period 1865–1996 was similar and, at times, higher than in the other areas, which results from the preference of cumulating of gangue on spoil tips as the cheapest way of its disposal, as well as from the dominance of caving coal extraction.

Antropocen: procesno stanje na rubu povijesti Zemlje?

Author(s): Peter Sloterdijk / Language(s): Croatian Issue: 25/2020

Kad je nizozemski atmosferski kemičar Paul J. Crutzen 2000. godine - posežući za analognim konceptom talijanskog geologa Stoppanija (1824. - 1891.) predložio izraz »antropocen«, kako bi današnje doba markirao iz prirodno-povijesne vizure, nametala se pretpostavka da će taj izraz ostati dijelom jednog hermetičkog diskursa, koji se koristi iza zatvorenih vrata instituta za analizu plina ili geofiziku. Zahvaljujući nepoznatoj seriji slučajnosti tom sintetičkom semantičkom virusu očito je uspjelo proći kroz dobro izolirana vrata laboratorija i proširiti se u općem životnom svijetu - pri čemu se stječe dojam da se posebno lako reproducira u kontekstu učenih feljtona, muzejskog pogona, makrosociologije, novih religioznih pokreta i ekološke alarmantne literature.

Antropogeniczne przekształcenie rzek na Ponidziu Pińczowskim

Author(s): Jarosław Suchożebrski / Language(s): Polish Issue: 3/2021

One of the three basic components of assessing ecological state is the determination of hydromorphological conditions occurring in river channels and valleys. In this paper an effort has been taken to check usefulness for such evaluations River Habitat Survey (RHS) – British research method, which is used in Poland for classification of ecological quality of surface waters from the view-point of their actual hydromorphological state. The possibilities of using this method in field teaching of geography students were checked. For this purpose, the RHS method was modified and adapted to the needs of field exercises. Research was conducted in Nida Riverside region, near Pińczów (świętokrzyskie voivodeship, Poland). Collected material makes it possible to calculate synthetic indicator HMS (Habitat Modification Score) which allow the hydromorphological state of a river to be presented in numerical form and assessing river modification by human activities. The research released advantages of the RHS in field teaching of students. The method can also be used in field exercises with secondary school students.

Antropogenicznie uwarunkowane przełomy Suminy i Wierzbnika jako przykład naturalizacji sztucznych koryt rzecznych (zlewnia Rudy)

Author(s): Maria Fajer / Language(s): Polish Issue: 153/2018

The article describes anthropogenic transformations of relief features associated with former economic use of rivers and the changes that occurred in individual sections of artificial canals as a result of their naturalisation. The study was carried out in two river valleys – of the Sumina and Wierzbnik Rivers, which are located in the Ruda River catchment (within the Odra River drainage basin), on the boundary of the Rybnik Plateau and the Racibórz Basin. The use of water in these rivers for the purposes of former grain mills, sawmills and other industrial facilities as well as fish ponds involved the construction of bypasses. The deep erosion gullies recorded in the relief of the Sumina and Wierzbnik River valleys are in fact transformed anthropogenic forms: artificial river channels and old bypasses. In the Wierzbnik River valley, these canals – today dead, but still visible in relief, reflect the technical solutions which were once used to protect ponds from damage during floods. The sections of old artificial canals such as the man-made channel of the Sumina River, are still subject to naturalisation processes, being were later transformed by natural fluvial processes. This is reflected in an increase in channel sinuosity and the development of meanders. It is proposed that the erosive forms described in the article be referred to as anthropogenically determined river gorges.

Application of remote sensing data for monitoring eutrophication of floodplain water bodies

Author(s): E. V. Fedonenko,O. M. Kunakh,Y. A. Chubchenko,O. V. Zhukov / Language(s): English Issue: 2/2022

The aim of this article was to investigate the influence of structural features of the floodplain water network on the spatial and temporal dynamics of chlorophyll-a concentration as an indicator of eutrophication. The research was conducted in the waters of the “Dnipro-Orilskiy” Nature Reserve. The geographic information base with polygonal objects which represented water bodies of the reserve was created on the basis of detailed geographical maps and the high resolution space images. The water bodies were characterized using such parameters as the distance of the water body centroid from the nearest shore of the Dnipro River, the area of the water body, the order of the water body and the connectivity of the water body. Chlorophyll-а concentration was estimated based on the surface algal bloom index. The information was obtained about 148 water bodies, 141 of which are water bodies in the floodplain of the Dnipro River. The area of floodplain water bodies within the reserve was 3.28 million m2. The area of floodplain water bodies ranged from 300–232,500 m2. Trophic State Index allows us to estimate the trophic level of Dnipro River waters as mesotrophic, water bodies of first and second order as eutrophic, and water bodies of third and fourth order as hypereutrophic. The dynamics of chlorophyll-a content in water followed the seasonal course of temperatures. The concentration was lowest in the cold period of the year and reached its maximum in the second half of summer. The autumn decrease occurred at the end of September. The seasonal course of air temperature was superimposed on the peculiarities of the temperature regime of a particular water body, which depended on its depth and flow rate. The time, water body area, distance from the Dnipro River channel, connectivity and order of water bodies were the statistically significant predictors of chlorophyll concentration in water and were able to explain 85% of the variation of this indicator. The increase in chlorophyll-a concentration with increasing order of a water body is due to a decrease in the intensity of water exchange and a decrease in the depth of water bodies of higher order. An increase in the order of a water body is accompanied by a branching network of water bodies, the ability of water bodies to clear sediments decreases. Sediment accumulation leads to a decrease in their depth. Warming of shallow ponds and accumulation of organic matter in them are factors of intensive growth of blue-green algae. The evacuation of surplus organic matter, which results from mass vegetation development with excessive nutrient inputs, is a key driver of the eutrophic regime of water bodies. The increasing importance of regulatory processes develops in agreement with an increase in chlorophyll-a concentration in a water body. The importance of the considered factors reaches the highest level in summer time, when simultaneous maximum warming of water bodies and minimum water level in them take place. Accordingly, the differences between deep and relatively cool water bodies and shallow water bodies that warm up quickly, which significantly stimulates the growth of organic mass, reach the greatest contrast. The spatial patterns of variation in chlorophylla concentration have a complex multiscale structure, indicating the multiple nature of the acting factors. The spatial variability was represented as a composition of broad-scale and medium-scale spatial processes. The broad-scale process is most dependent on connectivity, whereas for the medium-scale process the leading one is the effect of water body order.

Application of the Water Quality Index in the Timok River Basin (Serbia)

Author(s): Dragana Milijašević,Bojan Gavrilović,Suzana Lović Obradović / Language(s): English Issue: 3/2018

The paper presents an analysis of water pollution carried out on the basis of the combined physico-chemical Serbian Water Quality Index (WQI) in the Timok River basin. The analysis covers various parameters (oxygen saturation, Five-Day Biochemical Oxygen Demand or BOD5, ammonium ion concentration, pH value, Water Total Nitrogen or WTN, Total Suspended Solids or TSS, orthophosphate concentration, electrical conductivity, temperature and the fecal coliform bacteria parameter) the values of which were calculated for four hydrological stations within the basin. The data obtained at each measurement station were averaged using the annual arithmetic average mean. The annual WQI values were calculated for a twenty-five year period (1990–2014) and they were in the range between 12 and 92, which means that the quality of water varied, ranging from “very bad” to “excellent”. The obtained results were interpreted and the watercourse quality was assessed using the comparison of water quality indicators according to the Serbian Classification of Surface Waters and the WQI method. The worst water quality was recorded in the Borska Reka River. Certain SWQI values are the result of water quality changes caused by wastewater from human settlements, industrial facilities, agricultural sources and illegal waste disposal sites in the basin.

Are Heteroptera communities able to be bioindicators of urban environments?

Author(s): O. M. Kunakh,I. O. Fedyay / Language(s): English Issue: 2/2020

The Heteroptera is a group of animals associated with the vegetation cover. The conducted analysis indicates that groups of heteropterans in the urban environment have a pattern of reaction to the environmental factors, determined using the phytoindication method. In the study, we considered the following hypotheses: 1) phytoindicational assessments of ecological factors may explain the patterns of variation of the groups of heteropterans; 2) among Heteroptera species, comparatively homogenous ecological groups could be distinguished which are characterized by similar character of response to the effect of certain environmental factors; 3)these groups could be used for bioindication of the conditions of environment in urban ecosystems. Stationary collection of heteropterans was performed during three years from May to October of 2017–2019 on six plots in Kharkiv. The article describes factors which affect the structure of groups of Heteroptera within the ecosystem of the large city and assess the bioindication possibilities. The data presented in the article, as well as the conclusions drawn, are to a large extent associated with stenotopic species, most of which could be used as bioindicators of the condition of one or another biocenosis. According to the results of a taxonomical survey in the territory of Kharkiv, 180 species of Heteroptera were found, belonging to 120 genera and 17 families. The highest species diversity was seen for the family Miridae, accounting for 50 species (27.0% of the total number of counted species). Fewer species were identified as the representatives of families Lygaeidae – 46 species (24.9%) and Pentatomidae – 23 (12.4%). Family Rhopalidae was represented by 11 species (5.9%). Nabidae and Tingidae – 10 species each (5.4%). Families Coreidae – 8 (4.3%), Cydnidae and Scutelleridae – 4 species each (2.2%), Anthocoridae – 3 (1.6%). The families Berytidae, Piesmatidae, Pyrrhocoridae and Reduviidae were represented by only 2 species each (1.1%). Families Acanthosomatidae, Alydidae and Aradidae were represented by 1 species each, in total accounting for 1.5%. The reasonably high level of species and ecological diversities of Heteroptera in the territory of the city allows them to be used in bioindication studies. We determined comparatively homogenous ecological groups of heteropterans which have a similar pattern of response to the impact of certain environmental factors. The study demonstrates that phytoindicatory assessments of the ecological factors can explain the patterns of variation in groups of heteropterans, We determined the factors which have effects on the structure of the group of heteropterans within the metropolitan ecosystem. The level of their effect on groups of heteropterans within the city is different. The most influential were light and humidity. Comparison of potential and realized projections of ecological space allows us, to a certain extent, to generate hypotheses about the orientations of transformation of the group heteropterans.
