Abstract Rivers are hydromorphologically assessed in line with the Water Framework Directive. In order to assess the quality of the Parsęta River environment, the River Habitat Survey method was applied. The research studies, conducted in June 2016, provided an overview of hydromorphological issues, and also covered measurements and laboratory analyses on the quality of its waters. There were 24 measuring sections selected along the whole river. The selection of these sections took into account the representativeness of genetically various types of river valley, its size and discharge, and the variability of anthropogenic pressure. The assessment showed that the Parsęta River varies in natural quality (its HQA index ranged from 17 to 61) and that the modification of its valley is variable but generally low (its HMS index ranged from 0 to 33). Seventy-nine percent of the analysed sections were classified to the second (II) and third (III) hydromorphological classes, 8% to the first (I), and 13% to the fourth (IV). The central section of the Parsęta River has the highest degree of naturalness and the lowest degree of transformation. The river valley sections of kettle-hole origin are more transformed than those of fluvial origin. The quality of the Parsęta River waters assessed on the grounds of their physicochemical parameters indicates that the river is in good condition. The individual river water parameters are most often within the first (I) and second (II) classes. Any instances of the quality of waters being below the “good” level are due to phosphate concentrations exceeding the second (II) class and are contained within a 15-km stretch of the river below Białogard. A river section with a high degree of hydromorphological naturalness has the worst quality of waters.

Abstract Using the River Habitat Survey method in forecasting effects of river restoration. Research presents usability of the River Habitat Survey (RHS) evaluation method in forecasting effects of the Zielawa River restoration, performed in selected section between 18 + 960 km and 19 + 460 km. The EU so-called Water Framework Directive signalizes necessity of achieving a good ecological status of European rivers in the immediate future. Accordingly, river restoration is the main tool for already technically regulated rivers’ quality upgrading. Present research contains a collation of four proposed restoration works variants and the ecological evaluation of chosen river reach before and after initiating restoration works in accordance to various variants, using the RHS method. The conclusion is fact, that in dependence of established variant it is possible to receive improvement of ecological class from present Class V to Class IV (variants 1 and 2) or Class III (variants 3 and 4)

The aim of this study was to recognize the relationships between the physical characteristics of river reaches and the supported macrophyte assemblage, using the newly developed RHS (River Habitat Survey) method and dataset, and to test the following specific hypotheses: (i) whether there are correlations between the abundance of macrophyte groups and the physical environment variables, and (ii) whether these relationships vary between macrophyte groups with different morphology types. The Tamis river possesses a highly diverse habitat potential, while high values of HMS capture obviously to significantly modified habitat classes, significantly distinguishing the R1 and L1 spot-check as a hot spot along the area studied.

Latem 2014 roku zbadano przy wykorzystaniu metody River Habitat Survey (RHS) stan hydromorfologiczny górnego odcinka rzeki Ner. Posługiwanie się wymienioną metodą polega na przeprowadzeniu badań terenowych na wytypowanych odcinkach rzek. Podczas badań terenowych w specjalnych formularzach zbiera się kilkaset jakościowych i ilościowych parametrów dotyczących zarówno koryta rzecznego, jak i dna dolinnego, a także roślinności, użytkowania ziemi, budowli hydrotechnicznych itp. Zebrane dane pozwalają obliczyć dwa syntetyczne wskaźniki hydromorfologiczne, na podstawie których określa się klasę stanu hydromorfologicznego badanego odcinak rzeki. Do badań wybrano trzy odcinki: najwyższy odcinek Huta Wiskicka (I), następnie leżący niżej odcinek Gadka Stara (II) i odcinek najniższy – Lublinek (III). Odcinki badawcze I i II były położone poza granicami administracyjnymi Łodzi, natomiast odcinek III znajdował się w granicach miasta. Uzyskano umiarkowane i stosunkowo słabe oceny stanu hydromorfologicznego górnego odcinka Neru: odcinek najwyższy cechował stan słaby (klasa IV), odcinek środkowy miał stan umiarkowany (klasa III), a odcinek najniższy – stan zły (klasa V).

Abstract The aim of the study was a hydromorphological valorisation of the river valley in the Roztocze region using the British method - River Habitat Survey (RHS). As a result of field research two numerical indicators HMS (Habitat Modification Score) and HQA (Habitat Quality Assessment) were identified and purity water classes were defined. The river did not fulfil the requirements of the Water Framework Directive, because its state was defined as poor and moderate. On the base of physical and chemical parameters, in the majority of water studied the watercourses were classified to the first class of purity. Only in one segment waters were below the first class, or even out of class.
