  • Anthropogenic waste products utilization for old landfills rehabilitation

    • Abstract: The paper presents remedial problems of old large sanitary landfills, particularly of embankments type. One of the main problems on a such kind landfills is to secure slope stability. The stability reinforcement methods consist of retaining walls, berms (constructed with selected waste materials), geogrids and mattress constructed of scraped tires. Metallurgical slag backfill material can be used for filters protection of leachate drainage and for technological roads construction on the landfill. The applied slope reinforcements and assurance of the proper performance of the leachate drainage in the landfill are of the greatest importance for the landfill slope stability and further use of landfill areas. Above mentioned aspects are described on the example of large landfill, localized nearby Warsaw. Radiowo landfill was founded in 1962, and now is at the end of the period of its operating and therefore remedial works have been undertaken there. In the future Radiowo landfill area will be adopted for recreation and sports purposes (view points, skiing, cycle roads etc.).

  • A study of application of chalcedonite as a manganese dioxide carrier

    • Abstract: Chalcedonite is a sedimentary siliceous rock, which occurs at four deposits in Poland and is included into a group of unique rocks. Chalcedonite is utilized in water treatment technology, mostly as an effective filtration material due to its mesoporous structure and extended outer surface of the grains. This paper presents three different methods of impregnation of the mineral material (MDMC-1, MDMC-2, MDMC-3) by manganese dioxide. As an oxide carrier chalcedonite was used. The results of the chalcedonite surface modification with SEM-EDS technique were presented. It was found that the chalcedonite is a very good manganese dioxide carrier and the modification of the chalcedonite surface changes its chemical composition, structure and value of the specific surface area.

  • Application of the Bayesian Belief Nets in dam safety monitoring

    • Abstract: The systems for earth dam monitoring should enable measurements of basic physical parameters describing the behavior of the structure, including: soil water pressure, soil stress, displacements, leaks, and drainage discharges. In the case of earth dam safety assessment, the monitoring data are used to detect any anomalies in dam behavior. In this paper, the dam safety has been analyzed using the Bayesian Nets. Two types of information: water pressure measurements and drainage discharge measurements are used in analyses. The seepage anomalies in the Klimkówka Dam were considered in demonstrate the practical advantages of using the Bayesian Nets for monitoring data interpretation. Presented examples of the Bayesian Nets applications (forward and backward propagation) in analysis of seepage through earth dams show that this method can be an effective tool supporting an assessment of dams technical condition and monitoring of the dam safety.

  • Optimization of water management system operation while quality and
           quantity of water determined

    • Abstract: In this work the optimal operation of the water management system is analysed. The fundamental technical elements of the system are the water reservoirs and the network of the pipelines among the water reservoirs and between the water reservoirs and the water purification plants (WPPs). While the simulations of the optimal system operation, the vectors of the optimal flows are calculated, so that the total costs of the system operation determined by the quality factor F are minimal. The analytical solution for the dynamic optimization problem is the result of the application of the Pontryagin's maximum principle. The simulation models of the optimal operation of the water management system were created in Matlab/Simulink. While the analyses of the results, the optimal control of some actual water management systems may by studied.In this work the optimal operation of the water management system is analysed.

  • Comparison of precipitation totals measured by the automatic
           telepluviometer and the Hellmann rain gauge at the Warsaw Ursynów
           station in 2000-2010

    • Abstract: Popularization of automatic methods of measuring meteorological elements and substituting manual methods creates a problem of maintaining homogeneity of measurement series. In such situations it is necessary to conduct measurements simultaneously, i.e. using a method being introduced and a former method. The analysis of measurement series carried out simultaneously enables comparing and relating measurements made by a new apparatus to already existing results.The present paper includes the results of the analysis of differences between daily, monthly and seasonal atmospheric precipitation values coming from a 11-year series of simultaneous measurements with a telepluviometer and the Hellmann rain gauge.

  • Linkage of "Lakes Zwenkau-Cospuden" as one of the elements of land
           reclamation after the open-cast mines and its future importance for the
           development of the region

    • Abstract: The open-cast mine "Böhlen", closed in 1921, in 1969 was transformed into "Zwenkau"("Zw") open-cast mine. In the seventies, together with its smaller neighbouring mine "Cospuden"("Cs"), became one of the greatest enterprises of the Central German lignite mining area. In the last centuries Zw and Cs mines had an significant influence on the economic, technical and scientific progress of this region. Although the mines were in separate mining areas, very close relations of proximity existed between them, particularly in the superposition of the lowering ground water areas. Thus, the total mass of the mine tailings "Cospuden" in the mining sector "Zwenkau" was flattened and designed for land reclamation. Since the cessation of lignite mining in the area Böhlen/Zwenkau/Cospuden the south region from Leipzig has been changed fundamentally. The remaining holes, which mines left behind, became lakes. Along the lakes raised beaches, ports and holiday houses. Lusatia and Central German Mining Administration Company (LMBV), which is now responsible for the reclamation and rehabilitation of disused mines, proposed a new perspective of this region, perceived as a part of nature and human-being. The main emphasis has been placed on the development of created lakes, flow-up phase and good water quality assurance. Some of the new lakes are connected together with artificial canals and locks. This also relates to "Zwenkau-Cospuden Lakes" (LMBV 2009). In this article the methods of management former mining areas in the South from Leipzig, with the great accent put on the linkage of "Lakes Zwenkau-Cospuden", are described. Necessary test on the soil samples from this field are explained. Finally, the influence of the restoration of the area on the development of the region is shown.

  • Occurrence of nitrogen cycle bacteria in the Biebrza River

    • Abstract: This paper of the selected groups of nitrogen cycle bacteria in the Biebrza River was analysed. In the water samples the quantity of ammonifying bacteria, nitrifying bacteria, proteolitic bacteria was estimated and also selected water quality indicators were analysed. Large quantities of proteolitic bacteria and ammonifying bacteria were found while the quantity of nitrifying bacteria was very small. Water quality analyses proved high TOC concentrations and low nitrate as well as nitrite concentrations. It was found, that the mineral forms of nitrogen being the intensive product of organic matter degradation is not released (low concentrations of ammonia), but it is accumulated in microorganisms cells. Low concentrations of ammonia are limiting for the number of nitrifying bacteria. The seasonal character of the occurrence of all analysed bacteria groups was as well found. The analytical procedure used was adjusted for bacteriological research on rivers of low anthropopressure.

  • Mapping of Spatial Distribution of Soil Salinity and Alkalinity in a
           Semi-arid Region

    • Abstract: Spatial variability of salinity and alkalinity is important for site-specific management since they are the most important factors influencing soil quality and agricultural production. Geostatistical methods provide a means to study the heterogeneous nature of spatial distributions of soil salinity and alkalinity. The present study was carried out to evaluate the accuracy of different spatial interpolation methods including kriging, cokriging and IDW methods for prediction of spatial distribution of salinity (EC) and sodium adsorption ratio (SAR) in soils of Ziaran region in Qazvin province, Iran. The tracking of the soil profiles was done using a Garmin eTrex-H model global positioning system (GPS) receiver. Sampling was done with stratified random method and sixty soil samples from 0 to 15 cm depth were collected. After data normalization, the variograms were developed. For selecting the best model for competing on experimental variograms, the lower RSS value was used. Experimental variograms were fitted to spherical and exponential models. The best model for interpretative was selected by means of cross validation and error evaluation methods, such as RMSE method. The sum of Ca2+ + Mg2+ and Na+ concentration which were highly correlated with soil salinity and sodium adsorption ratio, respectively, are used as auxiliary parameters in this study. The results showed that kriging and cokriging methods were better than IDW method for prediction of EC and SAR. Finally, the soil EC and SAR maps were prepared, using different spatial interpolation methods in GIS environment.

  • A stress history and strain dependent stiffness of overconsolidated
           cohesive soil

    • Abstract: In the last three decades an interest has grown in prediction of soil stiffness. This is mainly due to enlightened nonlinearity of constitutive characteristic in small and intermediate range of strain. In the last decade this interest has been extended on natural undisturbed soil. The paper undertakes this subject with an attention focused on Quaternary heavy overconsoldated stiff sandy clay. Series of triaxial tests on reconstituted and natural material were carried out which provided data for setting up formula for calculation Young's modulus in a wide range of strain 10-2÷1.0%, representative for working ranges in engineering applications. Stress history, in the form of yielding stress, is also accounted for.

  • Turbulent kinetic energy of water in a compound channel

    • Abstract: The aim of the experimental research was the determination of water turbulent kinetic energy changes in a compound channel without and with rigid, emergent, vegetation existing on floodplains. Two tests for two various roughness of floodplains were realized. In the first test the surface of the main channel bed was smooth and made of concrete whereas the floodplains and sloping banks were covered by cement mortar composed with terrazzo. In the second test the covering of the floodplains was left as in the first test but additionally emergent vegetation (trees) growing on the floodplains were modeled by aluminium pipes. Instantaneous velocities were measured with use of a three-component acoustic Doppler velocity meter (ADV). The influence of trees, located on floodplains, on the distributions of turbulent kinetic energy in the main channel and on the floodplains were presented. The distributions of turbulent kinetic energy at different water depths were described by regression equations. Vertical distributions of turbulent kinetic energy on the floodplains and over the banks of the main channel were divided into three zones. Over the bottom of the main channel, four zones were determined, containing the middle zone of the flow field divided into two zones of different trends.

  • Analysis of the connections between hydromorphological conditions and
           biocenotic diversity on the example of the Zwoleńka River

    • Abstract: The paper presents the evaluation of ecological status of two hydromorphologically diverse stream reaches of the Zwoleńka River. The studied sections of 500 m length are localized in a natural river-bed (Siekierka) and river-bed transformed due to a regulation (Zwoleń). The hydromorphological assessment of the stream has been performed by means of River Habitat Survey method (RHS). Level of habitat transformation has been determined with a help of numerical indices of the method: HMS and HQA; their naturalness has been also evaluated. Biotic conditions have been evaluated on a base of macrophyte river assessment and benthos macroinvertebrates. Macroinvertebrates have been determined to the level of family and following water quality indices have been also calculated: BMWP-Pl, ASPT, and EPT%. Value of BMWP-Pl has revealed that waters within the natural section of the stream could be qualified to the II grade of quality, while those in transformed section - to III grade. Moreover, it has been found that EPT% indicator has been much higher in non-transformed section. Evaluation of examined stream sections on a basis of Macrophyte Index for Rivers (MIR) has revealed that the numerical value of the indicator has been almost unaffected by the river-bed transformation degree. In both cases, examined fragments of the stream have been qualified as the II grade. In addition, physicochemical determinations of water have been carried out. However, no substantial differences of water quality, that could influence on biocenotic diversity of those habitats, between analyzed stream sections, have been recorded. Content of organic particles in sediments as well as granulation characteristics have been determined as well.Therefore, the present research has allowed to learn some relationships between abiotic and biotic elements of a small lowland river, which can be an initial point for further studies.

  • Assessment of permeability and pore water pressure in Warsaw clays based
           on in situ measurements

    • Abstract: The paper presents the results of groundwater monitoring program executed for the water intake at Stegny test site and for the deep foundation of the hotel building. It has been observed that during the excavation of massive in the Warsaw clays, the hydrostatic distribution of the pore water pressure do not remain constant, but changes into a new equilibrium groundwater flow regime. Negative pore water pressure (due to unloading) results in the increasing of effective stress within the clay subsoil for the short time conditions. Nevertheless observations and measurements confirmed the hydrostatic distribution of the pore water pressure for the long term conditions. This fact has to be taken into account for the estimation of the geotechnical parameters for the long term stability of the structure and the general safety.

  • Technical and functional aspects of enforcement of natural fertilizer
           warehouses in respect of environmental protection

    • Abstract: The article raises issues related to the implementation and use of manure storage facilities in aspect of environmental protection.
      Authors take into account two main factors affecting the proper functioning of the manure storage facilities: technical and functional ones. In case of the technical aspects of implementation and use of manure storage facilities it is essential to respect the principles of BAT. However, in the case of the functional aspects the main factor is compliance with Polish and European Union regulations.

  • Modelling equilibrium data for manganese(II) sorption onto manganese
           dioxide modified chalcedonite using the non-linear regression method

    • Abstract: Manganese dioxide is characterized by the acidic type of surface and high value of negative surface charge. It shows sorption and oxidation properties to such pollutants as heavy metals, radionuclides, arsenate(III), iodide. In the water conditioning technology it is used to modify various materials, including chalcedonite, which was the subject of the research presented in this paper. The manganese(II) equilibrium sorption was modeled using the non-linear regression method and basing on the Langmuir, Freundlich, Redlich-Peterson as well as pseudo-Langmuir isotherm equations. The determination of the isotherm equations parameters was run in two ways: by the minimization of the sum of the squared errors (SSE) as well as the minimization of the average relative error (ARE). The experimental data was best described in the Langmuir's isotherm equation, with the determination coefficient r2 = 0.916. The calculated parameters of the equation equaled: qm = 1.07 mg/g and b = 1.55 L//mg. The three-parameter equations of Redlich-Peterson and pseudo-Langmuir, assuming the possibility of multilayer sorption, came down to the Langmuir's equation. It serves as proof of monolayer sorption of manganese(II) onto manganese dioxide modified chalcedonite.

  • Temporal variability of the selected flood parameters in the Biebrza River
           valley

    • Abstract: The paper presents the application of the hydrodynamic one-dimensional model of river flow based on St Venant equations for calculation of annual floods characteristics in the Lower Biebrza River Basin situated in the Northeast of Poland. This model was combined with the Digital Elevation Model (DEM) for determining of area of flooding, its mean depth and flood volume. The model was calibrated using measurements of flood extent and verified comparing calculated flood extent to satellite images. The water level values calculated with the numerical model of flood-flow for cross-sections were next used to determine the digital model of the floodwater table in the valley. Then, inundation extent maps and water depth maps were calculated for whole area of the valley by overlaying the DEM and water table layers. This procedure, flood simulations with the hydrodynamic model and GIS analysis for determinations of inundation extent, was repeated for each day of the analyzed period of 1966-2000. A set of each year maximum calculated areas of flooding with related mean water depths and flood volumes was created and it was submitted to the trend analysis in order to determine possible change tendencies. Statistical analysis of three above described time series of annual flood characteristics was conducted with the use of moving average technique and linear regression method. Moving averages were calculate in two variants: with time step of 5 years and of 10 years. Next, linear trends were calculated by linear regression method. The results indicate that the developed hydrodynamic model of river flow combined with the DEM was useful for the calculation of annual maximum floods in the Lower Biebrza Valley and their parameters. Analysis of calculated flood parameters variability within the analyzed time period of 1961-2000 show decreasing trends for investigated area. This means that results of climate changes are perceptible in investigated area and they form serious danger to riparian wetlands.

  • BOD measuring and modelling methods - review

    • Abstract: The article presents the method of measuring BOD in wastewater and characteristic different models which can by used for describing changes of BOD in next days. In the paper described eight models: Moore et al. (1950), Thomas (1950), Navone (1960), Fujimoto (1964), Hewitt et al. (1979), Adrian and Sanders (1992-1993) as well as Young and Clark (1965) used by Adrian and Sanders (1998), Borsuk and Stow (2000) and Manson et al. (2006). Comparison the models suggests that changing of BOD during the time are better describes by models second order or double exponential model (Manson et al. 2006) than models the first order.

  • Determination of plant characteristics used in discharge capacity
           

    • Abstract: Riparian vegetation type, composition, structure, and its abundance on floodplains exert a strong influence on riparian surface and subsurface hydrology and discharges of rivers and streams. The conditions of flood waters flow in such valley types are shaped by the existing vegetation cover. In this study, on the basis of vegetation inventory in four selected and representative basins, the substitute geometrical parameters of the medium and tall vegetation were determined and friction coefficients for low vegetation. These parameters were determined for 72 km2 forested watershed draining a 3rd order stream as affected by floodplain riparian vegetation on the Atlantic Coastal Plain in South Carolina, USA. The vegetation parameters, determined directly from the measurements, were verified against the rating curve, that was achieved from discharge measurements as well as from discharge capacity calculations of the valley cross-section. In discharge capacity calculation, the Pasche method was used to calculate the total Darcy-Weisbach friction factor for each cross section according to the type of vegetation and flow interaction between the main channel and vegetated areas. In this approach friction caused by interaction between the main channel and vegetated areas are taken into account. The calculations performed on the basis of determined geometrical parameters of tall vegetation, show good agreement between the model and the measurements.

  • Slope erosion control with the use of fly-ash and sewage sludge

    • Abstract: The paper presents alternative methods of the earth slopes reinforcement. The techniques proposed utilise recycled materials such as fly-ash and sewage sludge. It is described how implementation of fly-ash made capping materials and hydroseeding method (with the use of the sewage sludge) can effectively control high earth slopes erosion, based on the example of embankment type landfill where remedial works were proceeded. Moreover, it is assessed how the influence of the vegetation cover on engineered landfills, can significantly increase the safety factor of slopes.

  • Settlement evaluation of spread foundations on heavily preconsolidated
           cohesive soils

    • Abstract: The paper presents the results of field and laboratory tests performed on the heavily preconsolidated boulder clays which prevail on the campus of the Warsaw University of Life Sciences - SGGW as foundation layers. Based on the results of field and laboratory tests a problem of spatial variability assessment of the thickness of foundation layers and the soil parameters is discussed. Special attention is drawn to the selection of the design values of oedometer moduli and the suitability of calculation methods for settlement evaluation. Calculated settlements were approved by the field measurements performed during building construction.

  • Evaluation methods of agricultural potential in rural areas including
           environmental function

    • Abstract: The study focuses on the environmental evaluation of land in the territory of interest by means of assessing the non-production functions. This topic is currently becoming one of the crucial moments in agriculture, water management as well as nature and landscape conservation. The soil represents an important component of the environment and influences both the quality and the quantity of produced foodstuffs due to the fact that being an abiotic factor, the soil is a part of many different natural and artificial ecosystems, affecting thus the hydrosphere, atmosphere and biosphere. The soil provides nutrients for plant growth, necessary for animal as well as human nutrition. It plays an important part in recycling and detoxification of organic materials and in the cycles of many elements. The proposed solution consists in the evaluation of the non-production soil functions in a particular territory according to chosen, usually unchangeable, soil properties on the basis of the proposed method of rating. The method is based on creating evaluation classes comprising the individual categories of soil properties. The rating expressing particular categories indicates the range of the non-production functions within the soil-ecological units in the territory of interest. The research was carried out in a territory only moderately impacted by human industrial activities. The results of the evaluation of chosen soil functions can be used in the studies focused on landscape and soil protection or in the proposals of environment-friendly management models in accordance with the rules of agricultural policy included in appropriate regulations aimed at the protection of varied environmental components.
