Institutional projects
2024-2028 Geohazards
Johannes Amos Comenius Programme (P JAC), project No. CZ.02.01.01/00/22_008/0004605, Natural and anthropogenic georisks.
The main research objective of the Geohazards project is to understand natural and anthropogenic threats and risks in the Earth’s upper spheres, to explain their causes and to quantify their potential impacts on human society and infrastructures.
The research agenda supervised under the framework of the Geohazards programme is focused on the impact of climate change and landscape disturbance on hydrological extremes and changes in fluvial dynamics. Recent research is focused on development of riverscapes after extreme flooding and changing patterns of runoff in montane basins in response to climate change.

Czech Science Foundation (GAČR 1905011S, PI: Jakub Langhammer)
The research project examines the changing patterns of hydrometeorological extreme processes in montane areas of the Czech Republic and aims at the identification of changes in dynamics of extreme hydrometeorological processes in mountain basins, having a major effect on the Czech Republic's hydrological regime. The research fills the gaps in knowledge on changing patterns in spatial distribution, frequency, seasonality and magnitude of hydrometeorological extremes in montane catchments and their key driving forces.
2019-21 UAS monitoring of river systems response to forest disturbance
EU COST Action CA16219, LTC 19024, 2019-21 (principal investigator)
The research explores the potential of unmanned (UAS) technologies for monitoring the effects of climate change and forest disturbance on the dynamics of hydrological processes in mountain areas. The research uses the techniques of multispectral, thermal, and LiDAR UAS monitoring of landscape elements, crucial for the formation of runoff in headwater areas.
2018-19 UAV monitoring of the dynamics of the spread of bark beetle in Prague´s forests
Prague Environment grants, 2018-19 (principal investigator)
The project examines the dynamics of the bark beetle outbreak and forest disturbance in Prague´s forests. The UAV monitoring and Remote Sensing methods are applied to detect the hotspots of the forest disturbance, to monitoring of the dynamics of forest health status and to the detection of early stages of the forest disturbance.
2015-2017 Impact of landscape disturbance on the stream and basin connectivity
EU COST Action 1306, LD15130, 2015-17 (principal investigator)
The aim of the project was to assess the influence of landscape disturbance, mainly the changes in land use and land cover structure, forest disturbance, stream modifications on runoff response, flow dynamics, dynamics of fluvial processes and morphological changes in catchments, floodplains and streams.
The research will be focused on two types of environment sensible to the disturbance or long-term changes in basin and stream connectivity – the headwater areas of streams in montane regions and the catchments in rural areas. In headwater regions in montane regions the research will be focused on the changes in the dynamics of runoff response and fluvial processes in catchments and streams.In rural catchments, the research will be focused to the changes in the dynamics of erosion-sedimentation processes in river basins, to development of a floodplain and to lake basin siltation.
2012-2014 The impact of disturbance on the dynamics of fluvial processes in mountain landscapes
Czech Science Foundation GAČR P209/12/0997, 2012-14 (principal investigator)
The project examines the impact of disturbances in mountain landscapes, particularly changes in the structure, extent and health of forest vegetation as a result of different causal processes on the dynamics of fluvial processes.
The project analyzes the different types of landscape and forest disturbance, induced by different causal factors, such as the forest vegetation damage by pollution, bark beetle outbreak, wind storms or forest management, or modifications of river network, riverbed and floodplains. The effect of these changes on the dynamics of runoff and fluvial processes is analyzed using detailed monitoring of rainfall-runoff processes and field mapping of changes in morphological characteristics in channels and floodplains.
2005-2008 Long-term changes of river ecosystems in floodplains affected by extreme floods.
Czech Ministry of the Environment VaV VaV-SM/2/57/05, (principal investigator)
Research project focused on effect of extreme floods on ecosystems and morphological changes in floodplains and impact of anthropogenical changes in basins on course and consequences of the extreme floods. The solution is based on field mapping of flood consequences, analysis and geoinformatical treatment of influencing factors and scenario-based modelling the impact of measures in river basins. The project team is composed by researchers from Faculty of Science, Charles University and is completed by experts from cooperating institutions.
