Abstract The paper presents the classification of the hydromorphological condition of the Breń River according to the River Habitat Survey (RHS). The research of the hydromorphological assessment of the Breń River, which is a right-bank tributary of the Vistula River and almost entirely flows through the area of the Dąbrowa Tarnowska district was conducted in June 2015. The research sites were situated on the border of the Tarnów Plateau and the Vistula Lowland. The Breń River in these sections flows through rural areas used for agricultural purposes with low-density housing. The analysis of qualitative parameters describing the morphological characteristics were based on two synthetic indices of stream quality: Habitat Quality Assesment (HQA) and Habitat Modification Score (HMS). The calculated numerical values of the two indices proved that the sections of the Breń River correspond with the third and fifth class, which means a moderate (III) and very bad (V) hydromorphological condition.

River Habitat Survey

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.

One of the three basic components of assessing ecological state is the determination of hydromorphological conditions occurring in river channels and valleys. In this paper an effort has been taken to check usefulness for such evaluations River Habitat Survey (RHS) – British research method, which is used in Poland for classification of ecological quality of surface waters from the view-point of their actual hydromorphological state. The possibilities of using this method in field teaching of geography students were checked. For this purpose, the RHS method was modified and adapted to the needs of field exercises. Research was conducted in Nida Riverside region, near Pińczów (świętokrzyskie voivodeship, Poland). Collected material makes it possible to calculate synthetic indicator HMS (Habitat Modification Score) which allow the hydromorphological state of a river to be presented in numerical form and assessing river modification by human activities. The research released advantages of the RHS in field teaching of students. The method can also be used in field exercises with secondary school students.
