Risk of the residents, infrastructure and water bodies by flash floods and sediment transport in relation to land use - assessment in the scale of the Czech Republic
Original language description
The research project is presented, where risk of residents, infrastructure and water bodies by flash floods and sediment transport is assessed for whole territory of the Czech Republic. The methodology is based on GIS approach. In the first step flow accumulation over actual DEM and landscape pattern is applied for determination of critical points, where concentrated surface runoff is accumulated and driven into sensitive areas. In the second step, WATEM/SEDEM model, based on RUSLE approach, has been implemented, to select those of critical points, characterized by high sediment transport. Then the profiles are classified, according to flood and sediment transport probability and vulnerability (the magnitude of water and sediment transport and sensitivity of structures coincided with runoff trajectories). Simple scenarios of conservation measures are then applied to analyze possible future strategies to avoid harmful effects. The presentation introduces innovative methodology, how the
