Aim of the study The paper presents a study on geomorphological processes and forms in mountain streambeds, which may be attractive for tourists interested in geotourism. In such case we propose in the paper a new name of such geotourism: geofluviotourism).The authors focused on the description of river erosion and accumulation in the context of potential geosites. Fluvial processes and forms were...
Aim of the study The aim of the study was to identify the trends in changes in air and soil temperature and their relationship, as well as to investigate if short data set can be an indicator of local climate change. Material and methods The study was based on the data of air and soil temperature collected between 2009 and 2015 at Czarna gauging station. It includes calculation of the average daily,...
Aim of the study Industrial soilless cultivation of plants is associated with the formation of leachate, which may pose a threat to the environment. Their management is an important issue due to the limitation of the dissipation of ingredients in the environment, but also with the view to limiting the use of water, which in this type of cultivation is key not only in terms of quantity but also quality...
Objective of the work The objective of this publication is to evaluate the impact of forest areas and urbanized areas on process of river runoff over the years, along with an analysis of the development of hydrographs in selected catchments for the upper Vistula (Wisła) region. Material and methods For the purpose of the present analyses, the following data were used: vector data from the Computer...
Aim of the study The aim of the work is to assess the impact of pollution discharge limitation after the modernization of the ŁAM sewage treatment plant on pollutant loads in the middle section and downriver of the Ner river. In order to do this, pollutant concentrations and loads were compared in two periods: 1995–2003 and 2004–2011. Material and methods The sources of data included information obtained...
Aim of the study In this paper we attempt to determine the sediment flow conditions in the drainage system of the barrage in Łączany on the Wisła (Vistula) river. To this end, the distribution of suspended sediment concentration in the cross-sections of draining ditches was developed; the concentration profiles of suspended sediment in individual cross-sections of the main ditch were elaborated; and...
Aim of the study The aim of the paper is prepare a report on hydraulic structures on the Oława River in terms of constructing hydropower plants and assessing rivers hydropower potential. Material and methods There are no small hydropower plants (SHP) on the Oława River. The authors carried out measurements and calculations of flows and water levels for the period of 2005–2015, classified the humidity...
Aim of the study The aim of the study was to determine the parameters of the stream transport capacity using turbulent diffusion coefficients using the imaging technique and to compare them with the coefficients obtained as a result of the measurement with the ADV (acoustic Doppler velocimeter) probe in a compound channel. Materials and methods Model tests were carried out on a physical concrete model...
Aim of the paper The aim of the study was to analyse the reasons for the occurrence of intensive suspended load transport in the area of meander 1. The river load transport caused significant morphological changes in the Upper Oder River bed system. Material and methods For 16 years, the authors observed and studied the course of significant and quite intensive changes in the morphological system...
Aim of the paper The aim of the paper is to determine the hydraulic conditions in the high gradient meander-modular fish pass based on model tests in which the correct migration of aquatic organisms is ensured. Material and methods The concept of a new version of the meander fish pass was developed at the Water Laboratory at the University of Environmental and Life Sciences in Wroclaw. A characteristic...
Aim of the study The purpose of the article is to present the effects of work on developing a method for determining environmental channel flows that could be implemented as a tool for assessing the degree of possible use of water resources by humans without compromising the functioning of the broadly understood environment. Such a method is considered as an alternative to methods of minimum acceptable...
Aim of the study The aim of the article was to present the results of the analysis of puncture resistance of shielding and sealing geosynthetics. Standard qualification tests were carried out on a rigid support in accordance with PN-EN 14574: 2015-12. Four types of protective geotextiles with different thicknesses and weights as well as three types of geomembranes differing in thickness were used...
Aim of the study The aim of the paper is to assess changes in organization and supervision of bathing areas and sites occasionally used for bathing in Poland after the implementation of the Bathing Water Directive 2006/7/EC. Material and methods The study is based on the law regulation published in the Journal of Laws and Polish Monitor - Official Journals of the Republic of Poland). Also, Chief Sanitary...
Aim of the study Aim of the study is to provide a comparative assessment of event based (EBA4SUB) and continuous (COSMO4SUB) modeling approaches for rainfall-runoff modeling for small and ungauged basins, focusing on the influence of the Antecedent Moisture Condition (AMC) of the soil on the estimated design peak discharge. Material and methods The event based approach is the EBA4SUB software. It...
Aim of the study The aim of the study was to assess the degree of heavy metal pollution in bottom sediments of lakes on the basis of geochemical and ecotoxicological indicators. Material and methods The analysis was conducted for 16 lakes located in the Gniezno Lakeland in central-western Poland. The studied lakes were included in the research program obtained from the Inspector of Environmental Protection...
Aim of study The aim of the study was to assess the relationship between groundwater level, drought at aquifer, precipitation deficit and high air temperature. Materials and methods The analyses were developed on the basis of data from the Faculty of Agro- and Hydrometeorology Observatory of the Wrocław University of Environmental and Life Sciences in Wrocław-Swojec covering years 1969–2017. Data...
