Opis:: The necessity and purposefulness of the investments related to water retention are justified mostly due to the preservation of the environment equilibrium as well as due to its farming, anti-flood, landscape and recreation aspects. Reasonable water management where various forms of retention are used gives large chances for the mitigation of the effects of unfavorable phenomena related to its insufficient amount. The creation of plans regarding the formation of reservoirs accumulating water is not necessarily synonymous with their realization. The reason of problems connected with the implementation of plans regarding the formation of new reservoirs lies mainly in financial measures and in problems with obtaining them. Water deficit in Poland is the reason for which the principles of its national usage need to be complied with. Realization of plans at both Voivodeship and municipality level that are focused on small retention will contribute to considerable increase in the retention capacity and will enable considerable increase in available resources in hydrographic catchments of both the characterized area and the entire country. The paper presents the characteristics of the present state and assumes the perspective development of small water retention in the Podlaskie Voivodeship using the example of the Podlaskie Voivodeship.

Opis:: The study aimed at determining the changes in the trophic status of the processes associated with the risk of eutrophication in small retention reservoir in Korycin, characterized by agricultural performance of direct and indirect catchment. The study was conducted using the surface water samples that were collected systematically every month over four hydrological years (2008 to 2014) from three research points. Mean annual concentration of total phosphorus varied from 0.641 mg P/dm³ during research conducted in 2007/2008 to 0.874 mg P/dm³ in 2013/2014 showing an increasing trend from year to year. Taking into account the calculated average values, an upward trend can be seen along with particular years of the study from the annual average value of 1.44 mg N/dm³ determined in the first year to the value of 2.66 mg N/dm³ recorded in the last year of the study. It was observed during the study that in non-flowing parts of Korycin reservoir, plankton developed more abundantly than in the central fragments, where the flow of water is more intensive. A mild growth of phytoplankton in the waters of Korycin reservoir is provided by relatively low concentrations of chlorophyll “a” found during all research periods. Concentrations of chlorophyll “a” in waters of the reservoir were within the range of 4.08 to 5.21 g/dm³. At a Schindler coefficient > 2, this value, based on the Decree of the Minister of the Environment of 2011, should not exceed 7 and therefore waters of the Korycin reservoir during the research can be classified as the first class. Values of the general trophic level (Trophic State Index) during the first three years of the study ranged from 67.15 to 68.65, which enabled to count waters of the reservoir in Korycin to eutrophic ones. In the last year of the analyzes, this coefficient increased to a value of 72.43, classifying its waters as hypertrophic. The largest share in such a situation was expressed by TSI (TP), which ranged from 97.34 to 101.82, always classifying the waters to hypertrophic ones. In contrast, the indicator TSI (TN) ranged from 59.71 to 68.57 and it classified the reservoir waters to eutrophic, while TSI (Chl) to mesotrophic.

Opis:: Land consolidations represent a unique tool for managing the problems of the rural space. They help to settle the land property rights and meet the current requirements associated with the protection and formation of a stable, permanently sustainable rural landscape. In the Czech Republic, complex land consolidations have been completed in 1,965 cadastral areas out of the total 13,100, and in 2,134 more they are in the preparation phase (up to 1st September 2015). It means that about 60% of cadastral areas in CR still await land consolidation. Our study aimed to localize the priority localities (cadastral areas and regions) for preferential implementation of land consolidation. The authors selected three thematic factors to determine the risk of their occurrence in particular localities and, consequently, the need to initiate the land consolidation. The analysis is based on the assumption that the cadastral areas where land consolidations have been completed or are under way have already dealt with the above-mentioned risk factors or will do so soon. Therefore, such areas have not been included into our study. The key selected thematic factors relevant for the preferential implementation of land consolidation include: the risk of water and wind erosion in arable land, water management, and water retention in the landscape. For each of these three factors, a map of preferential localities (based on the degree of risk/suitability) was processed for initiation of land consolidation. At the same time, a simple multi-criteria analysis of the extent of the Czech Republic’s erosion (water and wind) has been prepared. The result of this analysis is the ranking of regions according to the degree of risk of erosion. The most vulnerable regions of the Czech Republic include Jihomoravský (South Moravian Region), Středočeský (Central Bohemia) and Pardubice.

Tytuł:: Water Retention Problem in the Mountain Areas: a Case of Sola River Flows, Polish Carpathians

Opis:: The paper considers mountain rivers, which usually feature high dynamics of hydrological phenomena. The variability of the Sola river flows in the Polish Carpathians is presented based on water-gauge measurements from the hydrological long-period of 1956-2015. The flows for the upper section of the river, where no storage reservoirs are found, were analysed. A broad range of flows was shown – from 0.59 to 1250 m³/s at a mean flow of 15.5 m³/s. It was also shown that within a year, the flows grow in the spring (thaw freshets) and summer periods (rainwater freshets). Mainly the summer freshets are dangerous, consisting in a sudden rise of the flow due to rains. This is shown by the high values of maximum flows in June and July. In the case of mountain rivers, such as the Sola river, it is necessary to undertake the actions stabilising the flows, which on the one hand have flood-prevention importance, and on the other hand protect the water resources in long dry periods. The actions should be concentrated on the proper arrangement of the catchment area, slowing down the rainwater outflow. Appropriate land use is especially important (distribution of forests, of arable and developed areas) depending on the land elevation above the sea level and inclination, as well as creation of small storage facilities.

Opis:: Water shortages occurring in the natural environment are the result of progressing climate changes, including the decreasing amount of atmospheric precipitation. In Poland, during the vegetation periods, droughts occur every 4-5 years, which causes losses in the field production and in forest communities. Reducing the negative effects of drought is possible by retention of water within a catchment. This method of improving the water balance has been included in the provisions of the Water Framework Directive and Water Law. On the meliorated valley objects, there are melioration devices that enable regulation of the moisture content, including irrigation during periods of drought. Drainage ditches can also retain water in the early spring periods with high flows in rivers. The studies carried out on the Lower Supraśl river site showed that about 40% of drainage devices used for water damming (dams and ramps), as well as for water distribution (feeders and detailed ditches) are not technically efficient and do not fulfil the function of moisture content regulation. Fibrous-muck soils occurring on this object, due to the lack of rainfall and irrigation, reduced the water retention capacity by approximately 30%. Modernization and reconstruction of drainage devices on valley objects will enable increasing the retention within individual catchments.

Opis:: In soils, where the water table is deeply located and has a minor impact on the moisture content of the surface layer, we are dealing with the precipitation-and-water type of water management. If underground water level is close to the surface, the top stratum of the soil, apart from precipitation, is additionally fed by water absorption from underground waters. Then we are dealing with ground-and-water type of manage-ment. We consider such types of water management of soil in the area of the left-bank valley of the Odra river, above and below the dam in Brzeg Dolny. The dominant soil types here are middle fen soils, based on middle clay and heavy clay as well as loam, which, in conditions of either excess or deficiency of moisture, are difficult to cultivate. The work compares water management of two soil profiles in vegetation periods between 2004 and 2009. The formation of underground waters, meteorologi-cal conditions and the course of the water reserves in the strata 0–50 cm and 0–100 cm were estimated with various supplying conditions of the active stratum of the soil. The volume of the supply with percolated water from underground water of the layer 50–100 cm on approximately 75–90 mm was also estimated. This value was mainly dependent on the depth of the retention of the water table of the soil profile above the level in Brzeg Dolny.

Opis:: The availability of water in adequate sufficient quantity and quality is the most important factor in maintenance of life and human activity. Surface water as easily accessible resources per citizen in Poland should not be compared to other countries of the European Union. Podlasie is a lowland region, which is dominated by vast plains occasionally varied by low hills with gentle slopes. Natural lakes occurring sparsely are heavily overgrown or completely restated as a result of moor succession. The storage of natural hollows which store water resulted in the construction of artificial dam reservoirs, allocated primarily to water accumulation. Lowland development of small retention mainly consists of increasing the retention capacity and prevention of drought and floods, while maintaining and supporting the development of the natural landscape. This article presents the characteristics of selected major small water reservoirs in Podlasie. Characterized and evaluated the susceptibility of dam reservoirs degradation: Czapielówka, Korycin, Otapy-Kiersnówek, Repczyce, Zarzeczany. To evaluate the susceptibility of degradation there was applied Schindler factor, which is the ratio of the accumulated surface water reservoir and its catchment area to the volume of the reservoir. In addition, the influence of development of catchment management and the degree of degradation has been evaluated. Realising aware of the limitations of the size of the water resources is suggested to take appropriate action to alleviate the degradation of artificial reservoirs.

Opis:: Physical and water properties of silt loam from the area of planned football field were tested and compared with analogous properties of several composites made in laboratory conditions from the collected material with a dominant sand share. The research was conducted in a view of silt loam and its composites usefulness for constructing a carrying layer of football fields. Water permeability of silt loam and composites, as well as retention abilities were tested. The created composites met the water permeability requirements specified by DIN 18035 standard for constructing carrying layer of football fields. On the other hand, silt loam without sand admixture did not meet the requirements, but revealed a high retention capacity and water availability to plants. Among the composites the best retention capacity characterised the mixtures with the biggest content of silt loam, but the best water availability was registered in composites with medium content of silt loam from the football field area. The obtained results may be useful for more precise determination of the standards for grain size distribution of the composites used for constructing the carrying layer of a football field.

Opis:: The study presents the characteristics of the Mściwojów Reservoir equipped with a unique pre-reservoir structure that supports the process of self-purification of waters. The authors present more than ten years of studies, focusing mainly on the issues of water quality and the concentration of phosphorus, which is considered as the main factor influencing water eutrophication process. Quite a high concentration of phosphates was noted in the outflow from the main reservoir, in spite of a lower concentration of these compounds in the water leaving the pre-reservoir. Basing on the conducted analyses, the catchment of the reservoir was qualified as group 4, being very prone to the movement and supply of material to the reservoir. The negative value of the retention coefficient of phosphorus obtained for the main part of the reservoir points to the existence of an internal source of phosphorus supply to the reservoir. During over 10 years of studies, new directions of the development of the rural areas were determined. Future works should be extended so as to cover all elements of the ecosystem of the reservoir. In a longer term it seems natural to extend the research works to cover the whole catchment of Wierzbiak River.
