The key to ecological revitalisation of river floodplains is improving the water regime, since this very important abiotic factor has undergone serious deteriorations due to anthropogenic effects. The desired improvement can be achieved by transforming the natural water conveyance infrastructure of the river-floodplain system in an appropriate manner. The proposed revitalisation has been tested on a case study problem dealing with the revitalisation of the Danube riparian Gemenc floodplain.
