ABSTRACT
The volume of transport and sedimentation of solid particles is important, among others, for water quality changes in the capacity of water reservoirs, work of water intakes for agricultural or water supply systems, shipping etc. This article concerns the process of transport and sedimentation of raised sediment and morphological changes in the bed and valley system caused by these processes. The authors observed for 16 years the course of such changes on the Polish-Czech border section of the Mountain Odra in the area of the village of Chałupki - Bohumin. The authors attempted to characterize the variability of the volume of transported sediment as discharge function and to assess the volume of transported load of sediment that caused such a rapid morphological change in the Odra riverbed. The analysis used measurement data from the water gauge section in Chałupki from 1969–2002, published in Hydrological Annals (1969–1983) and measurement data obtained from the Provincial Inspectorate for Environmental Protection in Katowice (1984–2002). The preliminary analysis of the volume of sediment transported as a function of flow showed significant variability, which made it impossible to clearly determine the functional relation. It was found that in the flow range up to about 250m3/s, the intensity of transported sediment increased. After exceeding the flow value of 250m3/s, the course of the phenomenon is disturbed which indicates the possibility that the amount of sediment eroded from the bottom of the river on the analyzed section is limited.
