Evaluation of the river system of the Odlezelské (Mladotické) Lake basin as a potential source for sediment transport
Mužák, Petr ; Kliment, Zdeněk (advisor) ; Šobr, Miroslav (referee)
The status of the river network is essential to understanding the fluvial system of the basin. Erosion and accumulation activities of the river system led to changes in the river channel which caused the increased sediment transport and contributed to the silting of the Odlezelské (Mladotické) Lake. This study aimed to evaluate the status of the river system of the Odlezelské Lake basin and to identify and characterize its erosion and accumulation of landforms. The field survey of the Odlezelské Lake basin applied the hydro morphological characteristics monitoring (HEM) method extended by the record of erosion and accumulative landforms. The Mladotický stream recorded the highest representation and area concentration of erosion landforms. The Potvorovský stream showed the highest density of accumulation of landforms. Anthropogenic activity changed the mapped part of the lake basin in 47 percent of sections which exhibited a lower degree of erosion and accumulation of landforms. Beaver population activities also significantly influence the fluvial dynamics of the river system. Keywords: river channel, fluvial dynamics, sediment transport, Odlezelské (Mladotické) Lake
