Monitoring of soil properties and groundwater level in alluvial floodplain forest

Popis výsledku v původním jazyce

The research of alluvial soils in the alluvial basin of the rivers Dyje and Morava indicates that the sediment deposits were not formed continuously, and the inundation process was regularly interrupted by no fl ood periods. That inundations and the appropriate groundwater level are essential factors of the alluvial soil-forming process. The meandering river Dyje is the axis of the studied region. The right river bank is covered by fl oodplain forests and the left bank is covered by meadows and permanent grasslands. The exploratory area of Mendel University Brno is situated in the fl oodplain forest near the town Lednice na Moravě (Czech Republic). Long-term systematic monitoring aims to follow changes in soil properties and forest growth as aff ected by climate change. Especially, the reduction of natural inundations after hydro-technical measures of the river bed directly aff ects the soil and the whole ecosystem. Moreover, the drop in the groundwater level caused many problems with drinking water for municipalities. Monthly monitoring of groundwater level, soil chemical and physical properties, and climatic conditions, is important for fl oodplain forest management. The studied soil was classifi ed as Gleyic Fluvisol Clayic. It was found that the heterogeneity of alluvial deposits and variability of the stand composition infl uenced the uneven distribution of nutrients and organic carbon in the soil profi le. Similarly, the bulk density and porosity values display a broad fl uctuation with depth. Measured results 97 were evaluated by one-way analyses ANOVA, followed by the Fisher test (p=0.05). The software Statistica 12.0 was applied. Obtained results also showed an increase in average temperature and drought periods during 2019-2022. The drop in groundwater level was observed especially during the summer and autumn periods. Floodplain forest growth was aff ected by drought periods as well. Continual measurements are important for preparing better forest management strategies such as artifi cial fl oods and legislation for the protection of this area.
