Anotace

Upper reaches of rivers are very important in a context of the whole river basin, because this parts represents zones of erosion. Eroded material is transported downstream the river basin. This high-gradient streams are mostly situated in the mounstains or in the forested uplands, as is the case Černá Opava. Studied area (the Černá Opava River Basin) in section from Rejvíz to Vrbno pod Pradědem in Hrubý Jeseník Mts. Was surveyed during summers 2012 and 2014. Černá Opava is the longest source of the river Opava and is characteristic by the black color due to the presence of organic substances coming from peat bogs. In the river basin I studied influence of topography, lithology and hydrologic regime to the fluvial forms. The most important part of this work is a field work including geomorphic mapping. I presented map of the geomorphic classification of the Černá Opava channel, which is one of the outputs. The most common type of channel is plane-bed, but there are also other interesting types (step-pool, colluvial, cascades,…). In this work I used classification of Montgomery, Buffington (1997, 1998) modified for local conditions. Next goal was mapping of direct anthropogenic influences in the channel. There are two main types - historical remains (flumes to the sawmills or iron mills) in the upper reaches. Recent channel regulations in the intravilan of Vrbno pod Pradědem (flood control measures after flood in 1997, straightening the river, conctering the channel,…). Second output is the map of human inpact to the channel of the Černá Opava river. In present time is the research extended about sediment flux conditions and mapping of natural and anthropogenic barriers to the movement of sediments. In this part I was inspired by the Fryirs et al. (2007), who studied (dis)continuity in sediment flux. Last map represent these specific forms affecting sediment flux.
