Monitoring and Evaluation of Groundwater Levels at Ladná Hydropedological Profile

Popis výsledku v původním jazyce

The planned construction of Oder-Danube canal was one of the largest projects of its kind, also giving rise to several research projects, including construction of boreholes for monitoring groundwater levels. Hydropedological profiles (HP) consist of boreholes, which are situated usually across the route of the canal and also across longitudinal axis of valleys or flat Moravian valleys. Profile Ladná is located north of Břeclav, passes through cadastral area of Charvatská Nová Ves and ends on the outskirts of the Lednice city. It is 4.98 km long and crosses the Thaya, Trkmanka and Včelínek rivers. It was built in 1948 and therefore has a 70-years long continuous monitoring data series. Over time, the location underwent several changes, most importantly the construction of the Nové Mlýny dam and modification of the Thaya riverbed. Dynamics of the groundwater level is assessed in the context of time and relationship with surface water levels, precipitation and geological profile during various reference periods. Groundwater level monitoring at hydropedological profiles is important especially because of linking the profile to a particular watercourse and duration of the continuous monitoring. It can also be used for determination of hydraulic link between surface water and groundwater. Groundwater level at boreholes is affected by river discharges and only to a very minor extent by precipitation. Given the length of the time series one can also evaluate periods. It seems that the most important period in case of most boreholes is the 12-month period, which corresponds to seasonal refill of groundwater. The occurrence of minimum groundwater levels has a period of approximately 10 years. Groundwater level in the Thaya basin decreased by about 0.5 m after the year 1972 and also the groundwater level fluctuation is smaller due to modifications of the Thaya riverbed.
