The paper focuses on issues related to the monitoring of changes in land use, which is a statutory obligation of voivodeship marshals in Poland. The analysis involved responses to author’s inquiries received from 16 marshal offices. The paper analysed whether and how marshals fulfil this obligation. At the second stage, the official replies were juxtaposed with relevant information from marshal offices’...
The aim of this study is to evaluate time distribution of gaseous pollutants’ concentration levels, sulphur dioxide (SO₂, μg · m⁻³), nitrogen dioxide (NO₂, μg · m⁻³) and to characterise biothermal conditions, based on subjective temperature index (STI, °C) in Legnica, Lower Silesian Voivodeship. Assessment of the seasonal and daily SO₂ and NO₂ concentration and STI values in the studied period was...
The reservoir complex in Zesławice on the Dłubnia River belongs to the Cracow agglomeration. It is located near built-up areas, which reduces the available flood reserve capacity and at the same time protects these areas. The experience of the flood in 2010 confirmed that this level is not sufficient, though. The main objective of this study is to evaluate the flood protection effectiveness of the...
The paper presents a study on the effects of different types of cement on selected properties of C30/37 road concrete. It involved three types of cement: Portland CEM I 42,5 R cement, Portland slag CEM II/B-S 32,5 R cement and CEM III/A 42,5 N LH/HSR/NA blast cement. The composition of the concrete mixtures were designed and evaluated experimentally. Test samples were prepared in laboratory conditions...
The aim of the article is to present the Record Sheet of Animate Natural Monuments for trees, which would standardize collecting and presenting data on tree monuments. The study uses data from the Register of Natural Monuments of the Lower Silesian Voivodeship made available by the Regional Directorate for Environmental Protection (RDOŚ) in Wrocław, as well as form the existing municipal record sheets...
The variability of water runoff and fluvial transport in the upper Wieprz River catchment (300.3 km2 ) in Central Roztocze region is presented, based on results of daily measurements in Guciów from the period of 1996–2016. The study period was characterised by high variability of annual precipitation totals – from 563.2 mm (2003) to 932.9 mm (2010), with the mean annual value of 735 mm. Mean annual...
Locating monasteries in river valleys with a considerable tributary system is regarded to be one of the rules for establishing Cistercian foundations: Bernardus valles, colles Benedictus amabat, Franciscus vicos, magnas Dominicus urbes. A river valley provided opportunity for spatial development and land cultivation on fertile ground, something that Cistercian monks specialized in. In their efforts...
The paper presents the results of monitoring electrical properties of the soil of the body of the earth-fill dam of the Karolinka water reservoir in the fourth year after its reconstruction ended. Monitoring was carried out using the Z-meter device applying the electric impedance spectrometry method with the focus on seepage through the earth-fill dam of the water reservoir. Information about the...
The historic town park in Zduńska Wola in its central and northern part is a designated conservation area pending on the local spatial development plan and the Registry of Historical Monuments. The composition of the park is diversified, with the highest elevation point in its northern part, sloping to the south towards the valley of the Pichna River which feeds two park ponds, including the bigger...
The paper presents an analysis of the tests of an airlift pump that has pumped water Qw or a mixture of water with sand Qw + Qs . The research included a determination of performance and efficiency characteristics for an airlift pump with internal diameter of the discharge pipeline d = 0.04 m equipped with a PM 50 air mixer with perforated rubber diaphragm. The tests were carried out for three lifting...
Geographical Information Systems (GIS) has revolutionised the process of collecting and processing data, therefore, more and more data recorded in an analogue form are transformed into the digital format. However, the process of generating vector models poses a risk of appearing defects of different types. A methodology of correcting common geometric and topological errors that appear in the manual...
The study included water samples from 10 test points located in the northern parts of Sanok and Lesko counties. The following analytical methods have been used: AAS (FAAS, CVAAS, HGAAS), ICP-MS, ICPOES, Ion chromatography, Acid-base titration, argentometry, turbidimetry and also bacteriological tests. Two sources were identified as “natural mineral hard medium-mineralised waters” with low iron content...
River valleys, apart from their natural values, have unique visual features. The perception of landscape is mainly determined by its spatial structure. Contemporary scientific research confirms significant compliance in the terms of ecological and aesthetic evaluations. The paper presents the results of the research carried out by the authors in the Valley of Samica Kierska River in Wielkopolska which...
The aim of the paper is an analysis of low flows – a phenomenon of persistent low water levels and flows in the riverbed – of the Vistula River at the Warszawa-Nadwilanówka gauging station. The study concerned the beginning of the 21st century, against the 1951–2000 period. In order to determine the low flows on the daily flows hydrographs, they were cut-off by the threshold level method. According...
The paper presents the influence of block ramp on system and morphological riverbed. One of twentyfive block ramp structures, located in the Porębianka River and situated in the central part of the cascade, was chosen for testing. In the observed section of the river, high morphological variability of the riverbed was observed in the years 2010–2011, caused by freshets. Additionally, in one period,...
All issues related to the maintenance of mountain rivers engineering structures, especially to river banks reinforcement, are extremely important to river engineering and flood protection works. The selection of appropriate hydraulic structures depends on many factors. When designing such devices, one should take into account, among other things, the type of soil, the hydrodynamic conditions, the...
Previous studies of drought in Poland practically neglected the aspect of groundwater shortage, focusing on atmospheric, agricultural and hydrological drought. Therefore, the aim of this work was groundwater drought analysis in selected sites of South-Western Poland, based on the analytical methods used in other European countries. The intermediate objective was to assess the possibility of using...
In paper, the ability to use of the biological early warning systems, in tap water quality biomonitoring was analyzed, based on multiple-criteria decision analysis. Five groups of organisms (invertebrates, fishes, algae, fungi and bacteria) were analyzed for the sensitivity to disturbance, the area of use, the amount of detected components, the rate of reaction and the data interpretation. Both analyzes...
The paper presents the concept of soil temperature coefficient, as a ratio of soil temperature in the given point on the area of a basin and soil temperature in the basal point located within the watershed. For modelling the distribution of the soil temperature coefficient depending on selected soil and physiographic parameters, artificial neural networks (ANN) were used. ANN were taught based on...
In the paper we present the evaluation of the effectiveness of the removal of biogenic compounds and indicator bacteria from domestic sewage in a vertical flow filter with a variety of fillings. The research was carried out on expanded clay, zeolite, calcined siliceous limestone, and crushed PET flakes. Based on the study of raw and treated wastewater, the effectiveness of removal of ammonium nitrogen,...
