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 to the adopted criterion, low flows are rather rare on the Vistula in Warsaw. The longest and most severe drought in terms of outflow deficit occurred in 1951. In the last years of the studied period (2003, 2012, 2015), droughts have reached a considerable sizes, but were no greater than the low flow observed in 1951. Since 1985 no winter low flows have been recorded.

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’ websites. The results suggest that not all marshals fulfil the obligation to monitor land use change. In most cases, the actions taken currently involve comparison of the current land use structure to the one of the previous year. This approach does not lead to proper conclusions from analyses and hinders taking appropriate decisions.

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 En vironmental Protection (RDOŚ) in Wrocław, as well as form the existing municipal record sheets of nature monuments and the Central Register of Forms of Nature Protection (CRFOP) facilitated by the General Di rectorate for Environmental Protection. Based on the qualitative assessment and the range of data contained in the RDOŚ and CRFOP registries and record sheets, an original proposal for a natural monument record sheet was elaborated for both individual trees and groups. The proposed consistent range of data on natural monuments will enable the use of collected data in statistical surveys, comparative analyses, and the research on species. In addition, the quality of data collection will contribute to a proper protection of trees and their surroundings.

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 to raise effectiveness of their production, they did not underestimate the importance of water, not only by developing their fishing ponds, but also making water the main driving force for water mills and fulling mills, thereby promoting modern rural ‘food’ industry such as distilleries, breweries and open-pan salt production. In today’s post-cistercian landscape, in spite of many centuries of economic landscape exploitation, we can still discover properly functioning natural systems and traces of comprehensively developed water systems. Using the solutions utilized in monasteries all around Europe, the Order managed to enrich and shape landscape in a very considerable and unique way, not only on economic and social, but ecological level, too.
将修道院建在具有相当支流系统的河谷中被认为是建立西多会基础的规则之一:Bernardus valles, colles Benedictus amabat, Franciscus vicos, magnas Dominicus urbes。河谷为空间开发和肥沃土地的耕种提供了机会，而这正是西多会僧侣所擅长的。在提高生产效益的过程中，他们没有低估水的重要性，不仅开发了鱼塘，还将水作为水磨和灌浆机的主要动力，从而促进了现代农村“食品”工业，如酿酒厂、啤酒厂和露天盐业。在今天的后蓄水池景观中，尽管经历了许多世纪的经济景观开发，我们仍然可以发现功能正常的自然系统和全面发展的水系统的痕迹。通过在欧洲各地的修道院中使用的解决方案，骑士团不仅在经济和社会层面，而且在生态层面，以一种非常可观和独特的方式丰富和塑造了景观。

Aim of paper The aim of research was to determine the sensitivity of the impedance spectrometry method (EIS) to changes in electrical resistance of soil caused by water infiltration. Materials and methods Two types of mineral soil were considered in the research: fine sand and coarse silty sand. The research was to determine basic geotechnical properties of both soils (filtration coefficient, soil-water characteristic curve) and water infiltration tests in a vertical soil column. These tests included measuring changes in electrical resistance of soil medium, which were compared with observations of the location of the wetting front and numerical calculations of water flow through the soil. Infiltration tests were run for three soil samples. The first was a sample of medium sand, the second coarse silty sand, and the third medium sand in the lower part and coarse silty sand in the upper part. Results and conclusions The results of tests of electrical resistance of soils subjected to infiltration process in vertical column confirmed the significant impact of water in soil medium on its electrical conductivity. It has been shown that a change in soil moisture from an air-dry state to full saturation leads to a reduction of soil resistance by almost three orders of magnitude.

Aim of the study In the present study, we aimed to verify empirical formulas for calculating mean low flow (MLF) with the view to evaluating available water resources for mountain catchments, located in the upper Vistula Basin. The following empirical formulas were analysed: Punzet and Stachý. Material and methods The studies were conducted in the following stages: analysis of significant trends for low flows in the analysed catchments, followed by the mean low flows determination using the analysed methods, and the determination of available water resources in relation to MLF obtained from the various analysed methods. Results and conclusions The analysis of the results showed lack of statistically significant trends in the course of low flows for the analysed catchments. Also, the analysis indicated significant differences between MLF derived from hydrological data and that derived from empirical formulas. The obtained results indicated the need to update the empirical formulas for calculating MLF, particularly regarding the determination of available water resources in ungauged catchments, in relation to mean low flows.

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 changes that occurred in the dam body before and after the implementation of the measure (the construction of a cut-off wall when the dam was reconstructed in 2013) was obtained by monitoring the changes of the electrical resistances of the soil of the dam with time.

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 one with an island, which closes a compositional axis, and the smaller one – a remnant of a long gone fire-fighting reservoir. The area holds considerable natural values, because of an old-growth forest and the described water system. Extensive research and numerous analyses were conducted in the course of the preparations for the park revalorisation. They included an assessment of the sanitary condition of the Pichna River waters, which flow through the park and feed the ponds. It turned out that the level of contamination (caused, among others, by discharges of untreated water from the nearby traffic routes) made it impossible to carry out the revalorisation, while letting for the ponds to be further fed with the river waters. In order to ensure a satisfactory level of water quality and clearness in both ponds, a decision was made to introduce complex and advanced technology to renovate the water system. The introduced solutions gained recognition from the Provincial Fund for Environmental Protection and Water Management, which granted considerable funding and an award in the contest ‘Natural treasures of the Łódzkie Voivodeship – program for the revitalisation of historical parks’.

Aim of the study Located to the south of the centre of Poznań city, Dębina is a valuable natural and landscape area, used for recreational purposes.This work’s objective is to identify natural values (assets) and landscape qualities and to establish the reasons for their transformation in the Dębina area, as well as determining the level of changes in land use and land cover, in order to capture the relationship between natural-landscape conditions and human activity. Material and methods In the course of the work, functional analysis and identification of contemporary threats for Dębina will be performed, based on the analysis of historical materials and contemporary cartographic materials using GIS tools. Results and conclusions Significant transformation of the environment in this area started with the construction of the water intake at the beginning of the twentieth century. Other investments related to the development of the city and the region also had a significant impact. The transformations that were unfavourable for natural environment and the landscape became the reason for taking corrective action, aimed at preserving and protecting natural components. Today, Dębina is an example of coexistence and interconnectedness between natural and cultural elements. As an area located in the Warta river valley, it is a part of an ecological corridor of national importance, and at the same time, it forms a part of the ECONET PL European ecological network. The results of the research – namely, determining the scale of the changes to land cover and land use in subsequent time periods – may become the basis for formulating guidelines for future management of this area, and for the protecting its natural values.
