This paper presents problems related to the church and the parish house construction the Vistula escarpment zone. Foundation slabs of design buildings are located AT 4.1–8.2 m below ground surface. Subsoil of buildings to 11 m depth consists the sandy Clay in a stiff condition. Below sandy clay layer the postglacial compacted sands are distinguished. The sate factors obtained for the Vistula escarpment...
The paper presents the basic characteristic of Domaniów reservoir. There is present the impact of the reservoir on the level of ecological values of the cross-border areas of three districts, where the reservoir is located. The paper also shows the costs and benefi ts resulting from the water investment which appeared with building the water reservoir and potential costs and benefi ts being able to...
The paper presents the characteristics of the shrinkage process (shrinkage curves, vertical, horizontal, total shrinkage and shrinkage geometry factor) for lowland medium decomposed moss, sedge, reed and alder peat collected from Biebrza Valley. For all considered peat types during the drying three phases of shrinkage process: structural, normal and residual were recognised. The highest total shrinkage...
The Biebrza River valley is the most valuable wetland’s complex in Poland. The biodiversity of endangered plants and animals observed in this region is outstanding. The lower river valley is considered as one of the most natural wetland area in Europe since, only small reach of this valley was drained. The conservation of this valuable object depends also on maintaining of high soil moisture, therefore...
In this study the recharge by precipitation of the upper Narew catchment was evaluated. Data from the MARS-STAT database and from the ground net of the rain gages belonging to the Institute of Meteorology and Water Management (IMGW) were acquired for the period 1978–2002. Analysis has indicated average 5% underestimation of the mean annual precipitation estimated with the MARS- -STAT data in comparison...
Doświadczenia polowe przeprowadzono w latach 2005 i 2006 w dwóch miejscowościach: Lipniku, koło Stargardu Szczecińskiego (gleba klasy bonitacyjnej IVb, kompleks przydatności rolniczej żytni dobry), i Kruszynie Krajeńskim, koło Bydgoszczy (gleba klasy bonitacyjnej V, kompleks przydatności rolniczej żytni słaby. Doświadczenia założono w układzie zależnym „split-plot” w 3 powtórzeniach. Badano dwa czynniki:...
Meteorological data collected by the author at Arctowski station from March to December 2008 revealed 72 days with hurricane winds in the Admiralty Bay. The results were compared with synoptic maps, wind data from Ferraz station and older data from Arctowski station. Winds in September 2008 reached the highest velocities (mean 32.0 m·s–1, gusts 80 m·s–1) ever measured in Admiralty Bay. 49% events...
The paper presents results of analyses hydraulic conditions of fl ow of weir in Jaktorów storied water for intake on fi shing pond in Agricultural Institution the Experimental WULS. During the fi eld inspection was made measurements: construction elements of weir, cross section on the length of storage in downstream and upstream. Flow capacity calculation of weir has been executed for different case...
The research of the sanitary state in three waters’ reservoirs situated within the area of three municipal park of Warsaw: Glinianki Szczęśliwickie, Glinianki Moczydłowskie and Jeziorko Kamionkowskie. The selected sanitary parameters of water quality in Reservoirs (bacteriological and chemical) were analyzed in May and July 2007. There was described existenexistence of fecal indicators in bacteriological...
In this review paper an aspect of constructed wetlands influence on retention of soil particles is presented. Most of “horizontal flow” – constructed wetlands over the world have been designed to treat municipal or domestic wastewater, but they are also successfully used to treat wastewaters from agriculture and various runoff waters. It is supposed, that constructed wetlands would be a useful, ecological...
A laboratory flume experiment was carried out with use of the selected species of aquatic plants, namely elodea canadensis. The measurements were carried out taking into account the changing depths, slope and vegetation density and their influence on the velocity distributions and the channel flow capacity was analyzed.
Paper presented results of investigation of formation local scour on the model of weir. Investigations were conducted on model with overflow under closure, bottom of water basins, horizontal bed protection in downstream and washing-out area. As eroded material on model sorted sand was used with d50 = 1.1 mm. Purpose of investigation were recognition variability dimension of scour during of discharge...
The aim of this work is calibration of a 1D numerical model of river flow within the Lower Biebrza Basin. To simulate the flow in the Biebrza valley, a one-dimensional unsteady open – channel flow model UNET, which is a component of computer software HEC-RAS, was applied. The geometry of the river channel and floodplain are described by cross sections in the number of 47. The river cross sections...
This article concerns problems with the eutrophicated water treatment process. The main thread of the article is dedicated to some causes and risks which are associated especially with many organisms living in polluted reservoirs. The main threat in particular comes from the toxic substances produced by Cyanophyta that is directly connected with its living processes which complicates the whole water...
The paper presents a comparative analysis of structural-material solutions of vertical baffl es in single-family housing. The subject of fi eld investigations were modern dwelling houses localized near Kętrzyn. Basing on 9 buildings, there have been presented some constructive solutions, the materials possible to application as well as the way of construction of the baffl es in an individual type...
The paper explains the term of energy efficiency building and characterizes the energetic standards of architecture and their influence on the architectural forms, which is connected to some controversial, esthetic and formal items, a bit harder to evaluate. The architectural forms of buildings being created nowadays have been classifi ed in three main groups: the traditional and moderate forms as...
The paper presents results of laboratory research on the zeolite and zeolite-sand blends using the electrical conductivity measurements to verify the sorption capacity of materials proposed to performance of the Permeable Reactive Barriers. First part of paper contains the characteristics of mathematical models commonly used to simulate the flowing of groundwater and liquid contaminants. In the second...
This article describes basics of Critical Chain concept and Buffer Management, as well as an approach to project management that comes from the Theory of Constraints. CCPM is a method with based on this particular concept. The article points out how to define place and the size of buffers to protect the due date and the critical chain of building object while preserving their specificity. This information...
The paper presents calculations of ultimate limit states and serviceability limit states of shallow foundation based on dense sand. It refers to the set of 6 design examples provided by European Technical Committee (ETC10), which was established by the International Society of Soil Mechanics and Geotechnical Engineering. Engineers and scientists were asked to supply their own solutions of the examples...
International Society of Soil Mechanics and Geotechnical Engineering have established European Technical Committee 10 (ETC 10) which main issue is an analysis and evaluation of implementation of Eurocode 7 rules into European countries engineering practice. During the works of ETC 10 a set of design examples was worked out, which was subsequently released in internet so as wider range of geotechnical...
