Opis:
Water erosion in mountainous areas is a major problem, especially on steep slopes exposed to intense precipitation. This paper presents the analysis of the topsoil loss using the SWAT (Soil and Water Assessment Tool) model. The SWAT model is a deterministic catchment model with a daily time step. It was designed to anticipate changes taking place in the catchment area, such as climate change and changes in land use and development, including the quantity and quality of water resources, soil erosion and agricultural production. In addition to hydrological and environmental aspects, the SWAT model is used to address socio-economic and demographic issues, such as water supply and food production. This program is integrated with QGIS software. The results were evaluated using the following statistical coefficients: determination (R2), Nash-Sutcliff model efficiency (NS), and percentage deviation index (PBIAS). An assessment of modelling results was made in terms of their variation according to different land cover scenarios. In the case of the scenario with no change in use, the average annual loss of topsoil (average upland sediment yield) was found to be 14.3 Mg∙ha-1. The maximum upland sediment yield was 94.6 Mg∙ha-1. On the other hand, there is an accumulation of soil material in the lower part of the catchment (in-stream sediment change), on average 13.27 Mg∙ha-1 per year.

Opis:
Agrophysics is a science dealing with physical properties and processes affecting plant production. The main topics of agrophysical investigations are mass ( water, air, plant nutrients) and energy (light, heat) exchange in the soil-plant-atmosphere continuum and way their regulation to reach biomass of high quantity and quality. Agrophisical investigations can be presented in the form of a tree - parameter system of classification. the term "Agrophysics" similarly to "Agrochemistry" "Agrobiology" "Agromelioration""Agroclimatology" or "Agroecology" has been fully accepted as an agricultural specialization. Agrophysics research are developed by meny scientific institutes but only the Instituí of Agrophysics in Lublin (Poland) is the strongest unit for a complex investigations in the field of agrophysics.AC The Institute of Agrophysics (IA PAN) is one of the institutes of the Polish Academy of Sciences, It was founded by Professor Bohdan Dobrzański in 1968 in Lublin who was the first and long-term director of the Institute (till 1980). The staff of the Institute consists of 100 workers including 68 scientific representing various specializations: physics, physicochemistry, soil science, agricultural engineering, mechanics, mathematics, electronics, geography and biology. These scientists have ery high qualifications achieved during long trainings in domestic and foreign centres. They were employed as postgraduate students and got their scientific degree on agrophysics. The Institute uses it's own building covering a surface of about 5 000 m2 situated in Lublin-Felin. The scientific structure of the Institute consists of six departments: 1. Hydrolherrnophysics of Soil Hnvironment and Agricultural Materials. 2. Aeration and Gas Exchange of Soil Environment and Agricultural Materials. 3. Mechanics of Agricultural Materials. 4. Physicochemistry of Agricultural Materials. 5. Agrophysical Bases of Soil Environment Management. 6. Physical Bases of the Evaluation and Improvement of Plant Materials, The Institute is a coordinator of agrophysical investigations in Poland and cooperates with meny scientific institutions over the world. The agrophysicial investigations carried out by the Institute and under its coordination allow us to deepen our fundamental knowledge about the physical and physicochemical properties and processes concerning agricultural materials. They also have introduced new elements to environmental protection which are significant to the economy. The results from these investigations may be used to: decrease soil physical degradation caused by erosion, soil crusting, sealing, compaction and structure destruction; increase the efficiency of water and fertilizer use; improve the technology of harvesting, storing and processing of plant materials to decrease quantitative ad qualitative losses of these materials; improve plant breading through formulation of physical properties of plants. The development of a theoretical basis in the field of agrophysics is of great importance for many agricultural specialization, e.g., soil science, soil technology, land reclamation, agricultural engineering, agroclimatology, agrochemistry, plant breeding and plant technology.

Opis:
Results of 10-years runoff plot experiments carried out on two sites of the Lublin Upland were presented. Despite similar soils and climatic conditions, studies showed large differences in annual soil erodibility (K factor of the USLE) between both sites. Experimentally derived values of the factor were dependent on tillage direction and time of maintaining runoff-plots in fallow conditions. On a site cultivated in contour direction, 4-year period was insufficient to achieve K values similar to the predicted values from the USLE. In contrast to this, on a site cultivated up-down slope, similar experimental and predicted K values were obtained after 2 years and remained at the same level during next 4 years. Results enabled to identify limitations of the USLE application for erosion prediction in Poland. Studies proved that soil erodibility could be used for prediction of erosion risk for silt loam developed from loess. However, application of soil erodibility approach to the event–base models is questionable for variation of K factor in the initial years. As far, the factors affecting soil erodibility changes are not recognized and need further research.
Koncepcja podatności gleby na erozję, zaproponowana w modelu USLE i wiążąca zespół parametrów glebowych z czynnikiem erozyjności opadu i spływu powierzchniowego, znajduje zastosowanie w wielu modelach prognozujących erozję wodną. W pracy przedstawiono wyniki 10-letnich badań poletkowych prowadzonych na dwóch obiektach Wyżyny Lubelskiej. Pomimo podobnych warunków klimatycznych, badania wykazały duże zróżnicowanie podatności lessowej gleby pyłowej na erozję (czynnika K modelu USLE). Stwierdzono, że różnice te były związane z kierunkiem uprawy roli oraz czasem utrzymywania poletek w stanie czarnego ugoru. Na obiekcie z uprawą w poprzek spadku zbocza, 4-letni okres utrzymywania w czarnym ugorze poletek okazał się niewystarczający do osiągnięcia wartości K zbliżonych do wartości prognozowanych z USLE. Na obiekcie z uprawą wzdłuż spadku zbocza, wartości eksperymentalne zbliżone do prognozowanych uzyskano po dwóch latach i utrzymywały się one na podobnym poziomie przez następne 4 lata. Uzyskane wyniki dowiodły, że podatność gleby na erozję może być wykorzystana do wyznaczenia obszarów potencjalnego zagrożenia erozją wodną w Polsce, które odzwierciedlałyby rzeczywisty stan zagrożenia gleb pozostających w słabej kulturze rolnej. Brak rozpoznania przyczyn zróżnicowania podatności gleby na erozję w okresie do osiągnięcia jej stabilizacji ogranicza możliwość wykorzystania czynnika K w modelach symulujących pojedyncze zdarzenia erozyjne. Nieuwzględnienie w tych modelach aktualnej wartości podatności gleby na erozję prowadzi do przeszacowania prognozowanych wielkości erozji. Określenie czynników warunkujących zróżnicowanie podatności gleby na erozję wymaga dalszych badań.

Opis:
Soil erosion is one of the most important phenomena affecting land composition and settlement. Among all natural causes of soil erosion such as rainfall intensity, temperature and wind, the human activity; massive deforestation and intensive agriculture, including the latest climate changes are considered as very important factors, especially nowadays. Thus, calculating the soil erosion coefficient appears very important in order to prevent the phenomena. Many methods are used to calculate such coefficient but in the presented research, the Erosion Potential Method was chosen. In this study, eight watersheds in southeastern Albania were evaluated. Results show that erosion is present in all considered watersheds. In one case (Panariti watershed) the erosion coefficient was very high; excessive, while in others it varies from heavy to very slight erosion. In conclusion, it can be stated that the Erosion Potential Method can be applied in the Albanian contest, same as in other neighbor countries. The results from Panariti, Roshani and Gianci should be further investigated due to the high quantity of soil eroded.

Opis:
This study aims to estimating annual soil erosion rate and its spatial distribution in the Bou Namoussa watershed located in the North-East of Algeria by applying the revised universal soil loss equation (RUSLE) within a Geographical Information System environment (GIS). The application of the RUSLE model in different natural environments and on every scale takes into account five key factors namely: the rainfall erosivity, the soil erodibility, the steepness and length of slopes, the vegetation cover and the conservation support practices. Each of these factors was generated in GIS as a raster layer, their combination, resulted in the development of a soil loss map indicating an average erosion rate of 7.8 t·ha–1·y–1. The obtained soil loss map was classified into four erosion severity classes; low, moderate, high and very high severity representing respectively 40, 30.48, 22.59 and 6.89% of the total surface. The areas, showing moderate, high and very high erosion rates which represent more than half of the basin area were found generally located in regions having high erodibility soils, steep slopes and low vegetation cover. These areas should be considered as priorities in future erosion control programs in order to decrease the siltation rate in the Cheffia reservoir.
Badania miały na celu oszacowanie rocznego tempa erozji gleb i jego przestrzennego zróżnicowania w zlewni Bou Namoussa w północnowschodniej Algierii z użyciem równania strat glebowych (RUSLE) w ramach systemu GIS. Aplikacja modelu RUSLE w różnych środowiskach naturalnych i w dowolnej skali uwzględnia 5 kluczowych czynników: zdolność erozyjną opadów, podatność gleb na erozję, nachylenie i długość stoków, pokrycie roślinnością i działania ochronne. Każdy z tych czynników został utworzony w GIS w formie warstwy rastrowej. Kombinacja tych warstw umożliwiła opracowanie mapy strat glebowych wskazującej średnie tempo strat równe 7,8 Mg·ha–1·rok–1. Wydzielono 4 klasy natężenia erozji: niskie, umiarkowane, wysokie i bardzo wysokie, reprezentowane odpowiednio na 40, 30,48, 22,59 i 6,89% całkowitej powierzchni. Obszary o umiarkowanym, wysokim i bardzo wysokim tempie erozji gleb pokrywające ponad połowę powierzchni zlewni były zlokalizowane głównie na glebach o wysokiej podatności na erozję, na stromych stokach i na terenach o ubogiej pokrywie roślinnej. Te obszary powinny być traktowane jako priorytetowe w trakcie konstruowania przyszłych programów ochrony przed erozją w celu zmniejszenia tempa zamulania zbiornika Cheffia.

Opis:
The control of water erosion is an important economic and societal challenge. Reduction of the agronomic potential of the parcels, muddy flows, siltation of dams are harmful consequences that mobilize farmers, water managers, local authorities and scientific researchers. This study focuses on mapping and quantifying seasonal soil losses in the territory of the former Nord-Pas-de-Calais administrative region, using the Revised Universal Soil Loss Equation (RUSLE) which incorporates five factors: rainfall erosivity, soil erodibility, topography, land use and erosion control practices. The seasonal (3-months) time scale is chosen to better account for the parameters governing the soil water erosion, especially rainfall and vegetation cover, that show great asynchronous intra-annual variability. Also, high resolution data concerning agricultural plots allows to evaluate which type of culture are the more subject to soil losses. In Nord-Pas-de-Calais, water erosion occurs almost ubiquitously, but the areas characterized by steep slopes are the most at risk (Artois Hills and Flanders), with loss rates up to 54 t∙ha-1∙y-1. The majority of erosion occurs during fall (46% of the computed annual losses of 1.69∙Mt), on plots left bare after harvest (especially corn and beets crops). The study also demonstrates that extending the intercrop technique over the region, and therefore maintaining a fall and winter cover, could reduce the soil losses by 37%.

Soil erosion is an important factor that should be considered when planning renewable natural resource projects, effects of which can be measured by modelling techniques. Therefore, disintegration models determine soil loss intensity and support soil conservation practices. This study estimates soil loss rates by water erosion using the Erosion Potential Method (EPM) in the Kebir Rhumel Watershed located in Northeast Algeria. The area is north to south sub-humid to semi-arid, receives irregular rainfall, and has steep slopes and low vegetation cover which makes it very vulnerable to erosion. The main factors in the EPM (soil erodibility, soil protection, slope, temperature, and rainfall) were evaluated using the Geographical Information System (GIS) and data provided by remote sensing technologies. The erosion intensity coefficient Z was 0.60, which indicates medium erosion intensity. While the results showed the average annual soil erosion of 17.92 Mg∙ha-1∙y -1, maximum and minimum losses are 190.50 Mg∙ha-1∙y-1 and 0.21 Mg∙ha-1∙y-1, respectively. The EPM model shows satisfactory results compared to some studies done in the basin, where the obtained results can be used for more appropriate management of land and water resources, sustainable planning, and environmental protection.

Opis:
Ekosystems which include all organisms living on a given area, together with physical environment, are connected between each other with processes of energy flow and matter circulation. The factors which condition existing of these processes in ecosystems are green plants, animals as well as funga and bacteria. These groups constitute trophic structure in the form of food chains. The general principle of ecosystem reduces to the fact that one organism is a source of food for the other, the latter for the next and so on. Tacing into account diversity of ecosystems, reflecting a series of elements of geographical environment, we deal with thermal diversity of the ground, which in turn, decides about absorption, dissipation or reflection of thermal energy reaching the surface of the Earth. These phenomena, recorded by thermovision systems can be located on thermogrammes. The problem to be discussed is determination of borders between ecosystem groups on the basis of superficial distribution of temperatures on thermogrammes recorded from a plane.

Opis:
Sediments are the major source of pollution in surface waters of the Pacific Northwest Region of the USA. The purpose of this study is to evaluate the relationship between SMI water quality scores at 76 sampling sites in eight watersheds and the observed soil erosion rates on adjacent landscapes. The water quality SMI scores in streams were obtained using stream macro invertebrates as an indicator of water quality, while soil erosion rates were determined by observation on adjoining landscapes during periods of maximum precipitation. Soil erosion rates of <2, 2–5, 5–15, 15–25 and >25 mt/ha/yr were observed at 9, 20, 45, 14 and 12% of the sampling sites, respectively. Landscapes with erosion rates of less than 5 mt/ha/yr generally resulted in good water quality in adjacent streams; however, when soil erosion rates on adjacent landscapes exceeded 5 mt/ha/yr SMI water quality scores were less than good 86% of the time. Strong signifi cant relationships were observed between SMI water quality rating and observed soil erosion rates. Consequently, land management or rehabilitation practices that reduce soil erosion rates to levels below 5 mt/ha/ /yr should improve stream water quality.
Rumowisko rzeczne stanowi główne źródło zanieczyszczenia wód powierzchniowych w zlewniach Pacyfiku w północno-zachodnim regionie USA. W pracy przedstawiono wyniki badań prowadzonych w ośmiu zlewniach w celu określenia zależności między indeksem jakości wody SMI w 76 przekrojach kontrolnych a wartościami wskaźnika erozji gleb na przyległych obszarach. Jako wskaźnik jakości wody do określenia wartość SMI wykorzystano badania makro bezkręgowców wodnych, natomiast wskaźnik erozji gleb określano na podstawie obserwacji terenu w okresach maksymalnych opadów deszczu. Uzyskano silną zależność między wartościami SMI a wartościami wskaźnika erozji gleb. Stwierdzono, że gdy wskaźnik erozji gleb przekraczał wartość 5 mt/ha/rok wówczas w 86% okresu obserwacji jakość wody była gorsza od dobrej, tj. słaba, zła lub bardzo zła. Zagospodarowanie terenu oraz działania w celu redukcji wartości wskaźnika erozji gleb poniżej 5 mt/ha/rok powinno poprawić jakość wody w ciekach.

Opis:
Soil microrelief is one of the factors affecting wind and water erosion process. Spatial variability of soil surface (microrelief) influences initiation of the surface runoff and water flow mainly through depressions, where the runoff is delayed and infiltration increases owing to the interception of the flowing water. The research was conducted to assess the changes of relief of two soils (sandy loam and fine sand) under the influence of rainfall in a model experiment. The soil microrelief was determined by means of a contactless 3D scanner using the effect of line distortion as light beam illuminating the object surface (so called Moire pattern). On the basis of obtained results, maps of the differences in the scanned surface elevations were plotted in ArcGIS programme and the soil losses volume was computed. RR indicator calculated for sandy loam was decreasing with increasing depth of simulated rainfall. No such dependence was observed for loose sand.

In the present paper, on the basis of altitude measurements, changes of topographic profiles of a chosen dried valley in Elizowkaon the arable land were presented. Intensity of water erosion was also studied on the unprotected loess terrain for 40 years.On the average, 22 cm of mud deposited on the tested section of the valley bottom (total area of 1.28 ha) along 500 m of the water race line, with the average width of 25.ʹ6 m. In consequence, the local erosion basis was raised and the average inclination decreased slightly. Physico-chemical properties did not significantly change within 40 years and these factors are typical of deluvial soils with unshaped profile. Their partial improvement points to reduction and stabilisation of erosion processes. That phenomenon is associated with slight thaw water run-off and the lack of larger storm precipitation.

Opis:
The subjects of this study were uncultivated mining waste heaps which are remnants of the territories abandoned after the exploration of iron ore. The aim of this analysis was the assessment of the influence of these objects on the soil located in the nearest surroundings, as well as estimation of the level of their degradation. It was ascertained that direct geomechanical degradation exists in the examined object, which is connected with soil profile destruction in consequence of transformation of hitherto existing geomorphological conditions, deformation of natural shape of territory, density of soil levels and deformation of the spatial layout. As a result of the examination, it was pointed out that chemical degradation as well as degradation of ecological structure occur on the analyzed territory. Progressing processes of water erosion on the side of waste heap are the consequence of improperly profiled, steep slopes causing the uncontrolled flow of rainwater, lack of flora and dense, micrograiny structure of soils which prevents the effective infiltration of water. Penetration of water into the ground causes the creation of channels which, in dry periods, can become additional pathways for the possible landslides.
