In the past few years, demands on flash flood forecasting have grown. The Flash Flood Indicator (FFI) is a system used at Czech Hydrometeorological Institute for evaluation of risk possible occurrence floods over whole Republic. FFI calculation based current soil saturation, physical-geographical characteristics every considered area, and radar-based quantitative precipitation estimates (QPEs) forecasts (QPFs). For higher reliability assessment, calculations QPEs QPFs are crucial,...
Flash floods are one of the most risky natural phenomena. It is very difficult to predict exactly where they will occur and usually come quickly. When there a threat flash floods, early warning what decides on protection lives property inhabitants. For these reasons, Flood Indicator (FFI) has being developed in Czech Hydrometeorological Institute (CHMI) for long time, aiming draw attention possibility flood or local flooding. The main purpose this contribution not describe details FFI...
Hydrological methods based on the analysis of data from a large sample catchments with different characteristics (large-sample hydrology; comparative hydrology) allow comprehensive hydrological regime and thus description variability change in components water balance. These provide insight into processes shaped by environmental climatic factors more general conclusions to be drawn. However, besides climate runoff data, catchment attributes, such as geology, soils, topography vegetation, are...
Data from interpolated daily rainfall totals for the period 1961–2020 were used area analysis of 1-day annual maxima. The was performed in a regular grid square areas ranging 16 to 324 km². For each and individual year, maximum areal derived between 15 April October. Datasets 60 seasonal values created further statistically processed. results analysed GIS environment. As expected, there are noticeable differences lowlands, uplands mountain general. In addition, regional visible, e.g. greater...

Rainfall-runoff modelling is widely used in the hydrological practice of CHMI. The presented text offers an insight into work Surface Water Department. use procedures described on specific selected examples such as derivation theoretical flood waves, evaluation and verification past events or its several applications operated at Hydrological also integral part scientific research activities with a focus updating methodological harmonizing input data.
Technologie geografických informačních systémů (GIS) jsou v úseku hydrologie Českého hydrometeorologického ústavu (ČHMÚ) velmi široce používány. Zpracování geoprostorových dat, jež se hydrologii používají při analytických úlohách, a rozvoj technologií GIS posledních dvou dekádách přispěly k rozšíření praxi ČHMÚ. Využití nástrojů je ukázáno na čtyřech příkladech. První z nich zaměřen vytváření dat GIS. Druhý příklad týká přípravy vstupních podkladů pro odvození hydrologických charakteristik...
