Spatial distribution of erosion and accumulation landforms within the river channel depending on the channel course and barriers for various large river
 Marková, Jana ; Křížek, Marek (advisor) ; Hartvich, Filip (referee)
The subject of the diploma thesis is the change in the spatial distribution of erosion and sediment deposition landforms within the channel of four different-size rivers, and is based on the morphology of the river channel and presence of barriers. The objective of this thesis was to 1) map the spatial distribution of channel bars and locations of bank scour, 2) define the morphologic characteristics including the position with respect to the location of bends and obstructions in the channel of the individual river reaches, and 3) define common patterns, and explain potential differences between the patterns in the rivers of different size. For the purpose of this study a field reconnaissance was carried out on selected reaches of Sazava River, Litavka River, Kocaba River and Lodenice River. The selected sections represent relatively natural parts of river channels with similar geomorphic conditions. The field survey was carried out in two campaigns - in spring and in summer 2015. The results of the survey indicate that channel bends do not play a primary role in the position and morphology of channel bars and locations of bank scour. However, significant sediment deposition or erosion activity was identified near run-of-river dams. In the surveyed reaches of the Sazava and Litavka rivers, channel...
