“…Mountain regions show high temporal and spatial diversification of all hydrological processes [13][14][15]. Therefore, disturbances of the hydrochemical regime in mountain rivers caused by the presence of reservoirs may bring about environmental effects that may be more unpredictable than in less diversified terrains.…”

Abstract:The aim of the analysis was to demonstrate the role of reservoirs in shaping nutrient content (nitrates NO3 -and phosphates PO4 3-as well as ammonia NH4 + ) in the waters of mountain rivers. Three Carpathian rivers with reservoirs in their courses were selected for the study: the Ropa River (Klimkowka reservoir), the Dunajec River (the Czorsztyn-Sromowce Wyzne reservoir complex) and the Raba River (Dobczyce reservoir). The basic criteria for the selection of the study objects for the investigation were: similar hydrological regime of the rivers and diverse parameters and functions of the storage reservoirs. The analysis of nutrient concentration was based on a long-term series of measurements (2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013). The reservoirs investigated generally contribute to an increase in nitrates in the rivers flowing below the reservoirs in particular months. The role of reservoirs in shaping phosphate and ammonia levels was not as evident as in the case of nitrates. The reservoirs are merely one of numerous factors that contribute to nutrient levels in the water of the mountains rivers. In the light of the analysis of nutrient concentrations in the surface water tested, it may be concluded that the reservoirs do not cause a clear and permanent deterioration of river water quality.

“…Besides the interruption to the continuity of the river caused by the reservoir, there are qualitative and quantitative changes to the natural environment of varying range and scale, which include, inter alia, transport of material, channel geomorphology, floodplains, riparian vegetation, biodiversity of riverine species and water quality (e.g. Baxter, 1977;Power et al, 1996;Kondolf, 1997;Grams and Schmidt, 2002;Magilligan et al, 2003;Hazel et al, 2006;Grams et al, 2007;Poff et al, 2007;Magilligan et al, 2008;Soja and Wiejaczka, 2014); Wiejaczka and Kijowska-Strugała, 2014). One of the fundamental effects of reservoirs are changes to the hydrologic regimes of rivers (e.g.…”

The Role of Reservoirs in Shaping The Dominant Cyclicity And Energy Of Mountain River Flows

The main objective of the paper is to determine the role of mountain reservoirs in shaping the dominant cyclicity and energy of river flows. The paper compares a large complex composed of two reservoirs (Czorsztyn–Sromowce Wyżne) with a smaller reservoir (Besko). These reservoirs are located in the Polish Carpathians and are characterised by very different parameters and functions. Moreover, they operate on rivers (the Dunajec and the Wisłok) with different hydrologic regimes. Using Fourier spectral analysis of daily inflows, outflows and water levels in reservoirs for the period 1998–2012, it has been possible to identify the dominant frequencies of the considered time series with a percentage of spectral energy for these frequencies. Moreover, for signals created by river flow rates, changes in signal energy are associated with adequate changes in river energy. Therefore, by calculating the energy of the signal in the time domain, changes in signal energy can be observed before and after the water passes through the reservoir. Data on cyclicity of water levels in these reservoirs forms the background to the analysis of reservoir‐induced changes in cyclicity of river flows. The conducted analysis revealed that reservoirs strengthen the regularity of the annual periodicity of stream flow in the studied rivers. Besides, these reservoirs significantly reduce the energy of water flowing out of them compared to the energy of inflow. Copyright © 2015 John Wiley & Sons, Ltd.

“…The River Habitat Survey (RHS) method was designed in the early 1990s by the British Environment Agency. It is the most common method applied in Europe to assess the hydromorphological state of rivers [4], [5]. Guidelines for conducting research with the RHS method are contained in studies by [1], [6].…”

The paper presents the results of studies concerning the assessment of the hydromorphological state and habitat quality of two Carpathian rivers (the Wisłok and Ropa rivers), along sections situated above and below the reservoirs operating in the course of these rivers. The investigation was carried out based on the British method called River Habitat Survey (RHS). On the basis of the data collected, for each study section, synthetic indices HQA (Habitat Quality Assessment) and HMS (Habitat Modification Score), which enable assessment of the river habitat quality, were calculated. The analysis performed indicates that the sections of the Wisłok river considered, both above and below the Besko reservoir, fall into Class 2, which points to a good hydromorphological state and habitat quality. The Ropa river is characterised by moderate hydromorphological state (Class 3) above the Klimkówka reservoir and by good state (Class 2) below its location.
