The Krzywaniec reservoir is a part of Dychów complex hydraulic engineering, and it was created as a damming up water of the Bóbr river in 42+700 km to wave elevation 73.30 NN. The river valley was divided by three span gate weir and tide gate to derivation channel to ESP Dychów. The Krzywaniec reservoir is currently silted up so that the probable water surface Q1% is going to reach reservoir site...
This paper shows variability of fluvial transport of the Wieprz river. The catchment of the upper Wieprz river to profile at Guciów located in Central Roztocze Region. In Wieprz during the hydrological years 1996–2006 average annual flow is 1.32 m3⋅s–1, which correspond to the outflow – 41.5 Mm3⋅a–1. Extreme values of the flows varied from 0.5 m3⋅s–1 to 13,1 m3⋅s–1. Outflow the Wieprz river has feature...
The paper presents the research carried out in the lower basin of Biebrza River valley in order to identify interception for natural wetland plant communities. Maximum interception, i.e. the largest amount of water, expressed in millimeters, which can be captured and retained by plant canopy from rainfall is one of the key parameters of the water cycle modeling. Maximum interception was determined...
The study area is located in the southern part of the Warsaw city agglomeration, adjacent to the Chojnowski Landscape Park. The study area is situated in the boundary zone between: (1) the bottom of the river valley reach with peat cover and (2) the Pleistocene glaciofl uvial plain on its lower level. The main aim of the study is the analysis of the investment impact on hydrogeological conditions...
This paper concerns the use of Terrestrial Laser Scanning (TLS) methods and the Geographic Information Systems (GIS) analysis to determine microtopography of a natural river valley, case study of the upper Biebrza valley. The scientific problem analyzed in this paper is a morphology of the selected segments of the valley covered by sedge ecosystems which in natural stage form a characteristic tussocks...
Nutrients availability and hydrological conditions of selected wetland ecosystems in the Biebrza river valley. Paper presents results of investigation of hydrological conditions and nutrients limitation and availability for wetland vegetation in selected sites within Biebrza river valley. Analysed sites were overgrown by tall sedge Magnocaricion vegetation (Caricetum gracilis and Caricetum elatae),...
