Project

Structure and dynamics of multi-species bed load transport above erodible plane bed in open channel (GA23-07772S)

of transport of well graded sediment through the layer in open channel with erodible bed in absence of bed forms. Across the transport layer, distribution of particles of sediment particles. The aim is to describe...

Modeling of intense transport of sediment in flood flow (GAP105/12/1082)

Flood discharges are often responsible for intense transport of sediments and mutual interaction between the flow and the conduit. A mechanism of sediment has been done, however, on an investigation of mechanisms of intense sedi...

Early diagenetic cycling of redox-sensitive geochemical proxies and palaeoclimatologic significance of continental red beds (GA22-15405S)

Continental red beds are traditionally viewed as indicating hot arid palaeoclimate. However, hematite enrichment and sediment reddening have been reported from table play a significant role in sediment reddening, which may ...

Heavy metals in small urban streams and optimal methods of sediment analysis (GP203/08/P387)

Heavy metals in urban streams represent actual problem. Their behavior during different conditions has not been very well understood yet. Moreover sediment sample extraction from sediment will be compared and conditions for applicat...

Erosion phenomena in Dyje river basin and their influence on heavy minerals contents in rush sediments of spate in August 2002 (Znojmo region) (RK04P03OMG005)

Heavy rainfalls in the river basin in August 2002 and the spate following (exceeding 500 years folw) caused an intensive erosion, transfer of old Weathered rocks and sedimentes and accumulation of the new ones. Morphology of the riverbed was...
