| Description | River landscapes represent key areas of great importance to human society as they perform many functions and provide valuable services. Traditionally, these areas have been perceived as geomorphological phenomena characterised by specific soil conditions, hydrological regimes and unique habitats. Due to the availability of detailed data, it is possible to perform a spatial delineation of river landscapes by interpreting these data using several different approaches. The results of these different approaches can vary considerably, since it is particularly challenging to define the river landscape along small watercourses for which the availability of suitable data is limited. The main aim of this study is to analyse the various methodological approaches that may be used to define the river landscapes of small streams, and to evaluate the efficiency of those approaches that can be applied in nature and landscape conservation. Two medium-sized catchments in the Czech Republic were selected as the study areas in order to ensure different natural conditions and degrees of anthropogenic pressure. As a result, an approach based on combining soil characteristics and topographic information is considered the most appropriate solution to delineate the river ecosystem. |
