FLOODPLAIN FORESTS IN SOUTHERN MORAVIA AND FLAP WEIR POHANSKO – A CHANCE TO SECURE WATER FOR FLOODPLAIN FORESTS AT THE CONFLUENCE OF THE MORAVA AND DYJE RIVERS
Alluvial forests in the lower floodplains of the Morava and Dyje rivers to their confluence are dependent on sufficient water from the rivers. Especially in the second half of the 20th century, there were big changes in the water regime of these forests related to construction improvements on these rivers. In the 1990s, measures were taken by local foresters to ensure sufficient water for floodplain forests. Currently, the state enterprise Lesy České republiky is preparing a new water project. The main goal of this project is the construction of a transverse weir in Dyje river, which will enable a better supply of water to the forests in the Soutok forest area below the town of Břeclav. The flap weir will enable the efficient use of water from the Dyje river and the inflow of water into the Soutok polder and the supply of water to the floodplain forest complex. The aim of these measures is to replace the natural water regime of floods, on which the biodiversity of the Special Areas of Conservation – SAC Soutok - Podluží depends.
