Abstrakt
The aim of the research emerged from necessity of gaining the long-term objective knowledge about salvage clear-cut area waterlogging and its changes due to impact of young plantation development in combination with hydroameliorative treatment. Investigation was done in a forested catchment on a waterlogged shoulder of the Orlické hory Mts. The paper deals with changing groundwater level of the first aquifer in a range from 0 to 0.9 m below ground, which was examined within a waterlogged part of the catchment. The changes are related to precipitation, streamflow discharge, run-off, influence of drainage treatment and growth of young forest stands. In the period of 2004 – 2008, the similar relationships were examined also for the second aquifer situated between 9 – 12 m below ground. For revealing relationships and proving significance, the Spearman’s coefficient of rank correlation was used. It can be concluded that changes of shallower aquifer does not respond to both precipitation and runoff so closely. The change of deeper groundwater table is perceptible only during long-term periods of rain or drought. Correlation between changes of groundwater level of both aquifers was not found.
