6 Abstract In recent decades the field of fluvial geomorphology has moved towards the most detailed and comprehensive description of the processes in fluvial systems. The recent development of UAVs (Unmanned Aerial Vehicles) has been a major contribution in analysis of fluvial processes, it provides very detailed data for change analysis. This thesis deals with the analysis of recent fluvial dynamics using UAV. The theoretical part of the thesis summarizes the current theoretical and methodological knowledge from the study of fluvial dynamics and also presents the general principles of UAV monitoring with its use in fluvial-geomorfological research. Recent fluvial dynamics was evaluated in the stretch of Javoří brook in Šumava Mountains where the long-term research is conducted by the Department of Physical Geography and Geoecology. Causal runoff events with an impact on fluvial dynamics were identified on the basis of the analysis of hydrometeorological data covering hydrological years from 2016 to 2020. A total of fourteen events exceeded the threshold of channel-forming discharge Q = 5,041 m3 ·s−1 in the investigated period. Geometrical, morphological and volume changes were evaluated based of the photogrammetric reconstruction of the riverbed during three successive scannings (2015, 2018, 2020). The...

Humans became an important factor in the development of Holocene relief. They began to significantly influence a plant cover and retention of the landscape with the advent of agriculture. The consequences of deforestation and an economic land use on erosion and accumulation processes are evaluated by comparing case studies from areas of Germany, Czech Republic and Poland. The main erosive processes belong to the end of Eneolithic, Late Bronze Age, the end of the Roman Period, and early Middle Ages in the area of interest. On a microscale, a stronger influence of archaeological situations arisen before the start of the erosion events and a substantial reduction of artefacts stored in situ can be expected.

This bachelor thesis' s main purpose is to earmark suitable examples of road networks considering water retention and accumulation both in rural and settled zones. The background research in this thesis presents theoretical survey about road networks in the cohesion with water. This research has been composed from the open sources, most of them valid technical standards and from the recommended literature. The second part of thesis includes demonstration focused on documentation of road networks already realized in compliance with technical knowledge contained in the background research (braced field road in the cadastre land Skřípov, Prostějov county; field roads including drains in the cadastre land Chotěbudice; main drain including road drain along the filed road C5 in cadastre land Vojnice).
