In the years 2014–2019, there was a historic drought in the Czech Republic. The Department of Hydrology and Hydrogeology of the T. G. Masaryk Water Research Institute has been carrying out long-term hydrological and hydrogeological observations in the upper Metuje basin where this drought manifested itself significantly. The upper part of the catchment area of the Metuje River is located in the Police Cretaceous basin geological formation.

Hodnocení erozní účinnosti deště je v současnosti těžištěm výzkumu v oblasti stanovení erozního ohrožení půdy. V rámci empirického modelování pomocí modelů rodiny USLE (the Universal Soil Loss Equation) je erozní účinnost deště reprezentována tzv. R faktorem, jehož hodnotu lze stanovit řadou doporučených postupů. Tento článek představuje možné alternativní způsoby určení hodnoty R faktoru na základě ročních a měsíčních sum srážkových úhrnů.
S překotným vývojem v oblasti geoinformačních a komunikačních technologií se objevují nové možnosti mapování a kvantifikace erozních procesů způsobených přívalovými srážkami. Pro získání relevantních výsledků je důležitá kvalita, hustota a rozsah vstupních dat. Rychlý a poměrně levný sběr přesných geodat umožňují bezpilotní letecké prostředky (UAV – z anglického Unmanned Aerial Vehicle). S využitím metod digitální fotogrammetrie je možné z pořízených leteckých snímků rekonstruovat morfologii terénu odpovídající času měření.
This study presents interim results of an evaluation of a potential climate change impact on the preservation of drinking water demand provided by water reservoirs in the timeframe of the year 2050. Hydrological and water sources and demands balance procedures have been applied, including modelling of the storage ability of water resources and water supply systems.
