Flash floods represent one of the most significant natural hazards in headwater catchments facing the lack of systematic hydrological monitoring. This study focus on the detection of flash floods on growth disturbances detected at trees of European beech (Fagus sylvatica L.) located in the torrential channel of the Holubi Potok stream in the Jizera Mountains (North Bohemia, Czech Republic). At the injured stems, flood scars were identified and core samples dated by tree ring analysis; the intensity of the disturba...

The aim of this study is to analyse impacts of the acid atmospheric deposition and global climate change on water resource recharge and water quality in headwater catchments of the Jizera Mountains (Czech Republic). Since 1982, a long-term hydrological investigation has been conducted in the experimental basin Jizerka (100 ha, elevation: 860-980 m, clear-cut of mature spruce stands and reforestation) and forest catchments of three water reservoirs Bed?ichov, Josef?v D?l and SouпїЅ. The пїЅopen fieldпїЅ load of sul...
